Top 15 Email Marketing Tools for Online Stores
Email marketing is one of the most useful digital marketing channels for online stores. It enables ecommerce businesses to communicate directly with customers, promote products, recover abandoned shopping carts, announce new arrivals, recommend relevant items, and encourage repeat purchases. Unlike social media campaigns that depend heavily on platform algorithms, email marketing gives businesses a direct way to reach people who have agreed to receive their messages.
However, successful ecommerce email marketing requires more than sending promotional newsletters. Online stores need tools that can connect with their ecommerce platforms, collect customer information, segment subscribers, automate messages, track sales, and measure campaign performance.
The right email marketing platform depends on the size of the store, the number of subscribers, the products being sold, the available marketing budget, and the complexity of the customer journey. A new store may need a simple, affordable tool, while an established ecommerce brand may require advanced segmentation, predictive analytics, SMS marketing, and sophisticated customer lifecycle automation.
This guide examines 15 email marketing tools for online stores, explaining their key features, advantages, limitations, and the types of ecommerce businesses that may benefit most from each platform.
1. Klaviyo
Klaviyo is an ecommerce-focused marketing platform designed to help online retailers turn customer data into personalized marketing campaigns. It is particularly popular with Shopify merchants and businesses that want to build sophisticated email and SMS marketing strategies around customer behavior.
One of Klaviyo’s major strengths is its ability to use ecommerce events, such as product views, purchases, checkout activity, and order history, to trigger relevant communications. Instead of sending the same message to every subscriber, a store can tailor emails according to what individual customers have browsed, purchased, or shown interest in.
Key Features
Klaviyo supports customer segmentation, automated email flows, abandoned-cart reminders, post-purchase follow-ups, product recommendations, and customer win-back campaigns. Depending on the configuration and available plan, businesses can also use predictive analytics to identify potential high-value customers or estimate purchasing behavior.
Its reporting tools help marketers evaluate revenue attributed to campaigns and automated flows. This can help retailers understand which messages influence purchases and where marketing improvements may be worthwhile.
For example, a skincare store could create separate segments for customers who purchase moisturizers, customers who buy sunscreen, and customers who have not purchased in several months. Each segment could receive product education, replenishment reminders, or relevant offers.
Advantages
Klaviyo is well suited to businesses that depend on customer data and repeat purchasing. Its ecommerce integrations and segmentation capabilities make it possible to develop detailed customer journeys without relying entirely on manual campaign scheduling.
Limitations
The platform can become expensive as a contact database grows. Its extensive functionality may also require time to configure properly. Stores with small customer lists and simple marketing requirements may not need all its advanced features.
Best for: Shopify stores, growing direct-to-consumer brands, and established retailers that want advanced ecommerce automation and revenue reporting.
2. Omnisend
Omnisend is an email marketing and automation platform developed specifically for ecommerce businesses. It combines email marketing with SMS and, where supported, web push notifications, allowing retailers to coordinate several communication channels within a marketing workflow.
The platform is designed to help online stores automate important stages of the customer journey. These include welcoming new subscribers, recovering abandoned carts, encouraging a second purchase, promoting special offers, and reconnecting with inactive customers.
Key Features
Omnisend offers campaign templates, audience segmentation, signup forms, promotional automation, product-focused messages, and ecommerce integrations. Its workflow builder allows marketers to combine email with other supported communication channels.
An online fashion retailer, for instance, could send a welcome email when someone subscribes, follow up with a personalized product selection, and send an abandoned-cart reminder if the shopper leaves without completing an order.
The business can also develop post-purchase workflows that provide order-related information, request product reviews, or recommend complementary products.
Advantages
Omnisend is useful for retailers that want ecommerce-focused automation without managing several separate marketing systems. Its templates and workflow tools can help smaller teams establish a consistent marketing process.
Limitations
Businesses should confirm that the integrations, messaging channels, and advanced reporting features they need are included in their chosen plan. SMS availability and costs may vary by destination and usage.
Best for: Small and medium-sized ecommerce businesses that want email, SMS, and automated customer journeys in one platform.
3. Mailchimp
Mailchimp is a widely used email marketing platform that supports newsletters, promotional campaigns, audience management, and marketing automation. Although it serves many types of businesses, it can also support online stores that want to manage customer communications from a relatively familiar interface.
Mailchimp is particularly useful for retailers that combine ecommerce with broader marketing activities, such as content publishing, events, lead generation, or customer surveys.
Key Features
Depending on the plan and connected store, Mailchimp provides email templates, audience segmentation, campaign analytics, signup forms, customer journeys, and ecommerce-related integrations.
A homeware store could use Mailchimp to announce a new product collection, send seasonal promotions, and follow up with subscribers who have shown interest in particular product categories.
The business might also create different campaigns for new customers, regular buyers, and subscribers who have not purchased recently.
Advantages
Mailchimp offers a broad marketing toolkit and a large ecosystem of integrations. Its campaign editor and templates can help businesses produce professional-looking emails without requiring advanced design skills.
It may also suit businesses that want email marketing to support activities beyond their online shop.
Limitations
Retailers seeking highly advanced ecommerce segmentation and predictive customer analytics should compare its capabilities with platforms designed primarily for online stores. Costs and feature availability can change as contact lists grow or more advanced automation becomes necessary.
Best for: Small online stores that want a general-purpose marketing platform for campaigns, newsletters, and customer engagement.
4. Brevo
Brevo combines email marketing, marketing automation, contact management, and additional communication tools. Its pricing model has traditionally emphasized email sending volume rather than charging solely according to the number of contacts stored, although the details depend on the current plan.
This approach can be attractive to stores with substantial contact databases that send campaigns periodically rather than emailing their entire audience every day.
Key Features
Brevo supports email campaign creation, subscriber segmentation, automated workflows, signup forms, and transactional email capabilities. Depending on the plan, retailers can also access SMS marketing, customer relationship management features, and other communication options.
For example, an online electronics retailer could maintain a large subscriber list while sending targeted campaigns only when new products arrive or relevant promotions become available.
The store could also separate promotional messages from essential transactional communications, helping it organize customer messaging more effectively.
Advantages
Brevo can offer flexibility for businesses that want marketing and transactional communications within a broader platform. Its combination of email, automation, and contact management may reduce the need to maintain several disconnected systems.
Limitations
The depth of ecommerce-specific analytics and store-event automation may differ from platforms built around detailed retail customer data. Businesses should check the available integrations and confirm whether their required workflows are supported on their intended plan.
Best for: Budget-conscious online retailers, stores with larger contact lists, and businesses that need both marketing and transactional email capabilities.
5. MailerLite
MailerLite is an email marketing platform known for its straightforward campaign creation and accessible interface. It is particularly suitable for smaller businesses that want to develop an email list and run regular promotions without managing a complicated marketing system.
For an online store, MailerLite can support newsletters, product announcements, educational content, and basic customer nurturing.
Key Features
MailerLite includes email design tools, signup forms, landing pages, subscriber groups, automation workflows, and campaign reporting. Ecommerce-related functionality depends on the connected platform and subscription plan.
A small business selling handmade candles, for example, could create a signup form offering customers a discount on their first order. New subscribers could then receive a welcome email, product-care information, and updates about seasonal collections.
The store could also send newsletters featuring gift recommendations and recently released products.
Advantages
MailerLite is generally approachable for business owners who are learning email marketing. Its visual editor and audience management features can help a small team establish consistent communication with customers.
The platform can also support content-driven marketing, making it useful for stores that publish buying guides, product tutorials, or other educational material.
Limitations
Stores requiring highly detailed purchase-based segmentation, predictive analytics, or advanced ecommerce reporting may eventually need a more specialized solution. Businesses should confirm which ecommerce automations are available on the plan they intend to use.
Best for: Startups, independent retailers, handmade-product businesses, and small stores with straightforward email marketing requirements.
6. ActiveCampaign
ActiveCampaign combines email marketing, customer relationship management, and automation. It is particularly useful for businesses that need to coordinate customer communications across multiple stages of a longer purchasing journey.
Although it is not exclusively an ecommerce platform, its automation capabilities can support retailers with complex customer relationships, repeat-purchase programs, and additional sales processes.
Key Features
The platform provides automated email sequences, segmentation, behavioral triggers, contact scoring, and CRM functionality. Integrations can connect ecommerce activity with customer records and marketing workflows.
Consider a store selling premium coffee equipment. Customers who purchase an espresso machine could receive setup guidance, maintenance advice, and later recommendations for compatible accessories.
The store could use different follow-up sequences for customers who purchase entry-level products and those who purchase higher-value equipment.
Advantages
ActiveCampaign is useful when a retailer wants to coordinate customer data, marketing automation, and sales follow-up. Its workflow capabilities can support detailed communication strategies based on customer actions.
Limitations
Its range of features may be excessive for a store that only needs to send occasional promotional newsletters. Implementation can also require planning, especially when several integrations and automated journeys are involved.
Best for: Growing ecommerce businesses that need sophisticated automation, customer lifecycle management, and CRM functionality.
7. Drip
Drip is an ecommerce-oriented email marketing platform designed to help online retailers personalize campaigns and automate communications using customer behavior.
It focuses on using store activity to develop relevant customer journeys rather than treating every subscriber as part of a single undifferentiated mailing list.
Key Features
Drip supports ecommerce integrations, automated email workflows, customer segmentation, campaign reporting, and behavior-based marketing. Depending on the connected store and configuration, marketers can create journeys around purchases, browsing activity, and other customer events.
For example, a beauty retailer could segment customers according to the types of products they buy. Customers who purchase cleansers might receive skincare routines and recommendations for compatible moisturizers, while makeup buyers receive updates about new colors and product collections.
Drip can also help stores develop win-back campaigns for customers who have not purchased recently.
Advantages
Its ecommerce orientation makes it useful for retailers that want to connect customer behavior with targeted marketing. Segmentation and automation can help businesses reduce repetitive manual campaign work.
Limitations
The platform may not be the best choice for businesses seeking an extensive all-in-one CRM or a large suite of unrelated marketing tools. Retailers should compare current pricing, integration support, and reporting features before committing.
Best for: Ecommerce brands that want behavior-based email campaigns and automated customer lifecycle marketing.
8. GetResponse
GetResponse is a marketing platform that combines email marketing with automation, landing pages, audience management, and additional tools for digital campaigns. It can support online retailers that want to promote products while also attracting visitors through educational content, lead magnets, or online events.
Its broader marketing functionality makes it relevant to businesses that sell both physical products and digital offerings.
Key Features
GetResponse provides email templates, campaign reporting, automation workflows, landing pages, forms, and ecommerce-related integrations. Available features vary by plan.
A retailer selling fitness equipment could publish a downloadable home-workout guide to attract subscribers. After registration, subscribers could receive a welcome sequence, practical fitness advice, and product recommendations based on their interests.
The store could then send promotional campaigns for exercise equipment, accessories, or seasonal offers.
Advantages
GetResponse can combine subscriber acquisition with ongoing email communication. Businesses that rely on landing pages and content-led marketing may appreciate having these tools within the same ecosystem.
Limitations
Retailers should verify that the platform supports their particular ecommerce system and required purchase-triggered workflows. Stores with highly specialized product recommendation or revenue-attribution requirements may prefer a more ecommerce-focused service.
Best for: Online stores that combine product sales with content marketing, lead generation, or digital products.
9. AWeber
AWeber is an established email marketing platform that helps businesses build subscriber lists, send campaigns, and automate customer communications. It can suit smaller retailers that want a dependable foundation for newsletters and promotional emails.
The platform is also relevant to entrepreneurs who sell physical products alongside educational content, guides, or digital downloads.
Key Features
AWeber offers email templates, subscriber management, signup forms, automation, and campaign reporting. Integration options can connect it to ecommerce platforms and other business applications.
A small gardening store, for example, could encourage website visitors to subscribe to a newsletter containing seasonal planting tips. Subscribers could then receive product recommendations for seeds, tools, and gardening supplies relevant to the season.
The business could also use newsletters to announce restocked products and limited-time offers.
Advantages
AWeber provides a relatively accessible approach to email marketing and can help small teams establish regular communication with subscribers.
Its content-oriented approach can be useful for stores that want to build trust by educating customers rather than relying exclusively on discounts.
Limitations
Retailers should compare its ecommerce automation and behavioral segmentation features with more specialized platforms before choosing it for a complex online store.
Best for: Small retailers, independent entrepreneurs, and stores that rely on newsletters and educational content to attract repeat customers.
10. Constant Contact
Constant Contact is an email marketing platform designed to help small businesses manage campaigns, customer communications, and promotional activities. It can be a practical option for retailers that combine online sales with local events, physical locations, or community-focused marketing.
For businesses that want to communicate with both online and offline customers, this broader small-business orientation can be useful.
Key Features
The platform provides email campaign creation, contact management, templates, marketing reporting, and tools for promoting events or offers. Ecommerce functionality depends on the integrations and plan selected.
A local gift shop with an online store could use Constant Contact to announce seasonal collections, promote holiday gift bundles, and invite customers to in-store events.
It could also send separate campaigns to subscribers interested in different product categories.
Advantages
Constant Contact can support retailers that want to coordinate email promotions with wider business activities. Its templates and campaign tools can help small teams produce consistent marketing communications.
Limitations
Stores that need highly granular ecommerce data, complex purchase-triggered journeys, or extensive predictive analytics should compare it with more specialized alternatives.
Best for: Small retailers with online and offline sales, local customer communities, and event-based promotional activities.
11. HubSpot Marketing Hub
HubSpot Marketing Hub combines marketing automation with contact management and CRM data. It is particularly relevant to ecommerce businesses that want to understand customers across several touchpoints rather than managing email activity in isolation.
It may be valuable for retailers with high-value products, wholesale customers, subscription services, or sales processes that involve personal follow-up.
Key Features
HubSpot offers email marketing, automation workflows, forms, contact segmentation, reporting, and CRM integration. The available features depend on the selected subscription and connected ecommerce applications.
For example, a business selling office furniture to both consumers and companies could use customer records to distinguish individual shoppers from corporate buyers.
The retailer could send product education to new leads, follow up with customers who request quotations, and provide relevant updates to previous buyers.
Advantages
HubSpot can connect marketing communications with a broader view of customer relationships. This is especially useful when a store has sales representatives, customer service teams, or several channels for generating leads.
Limitations
Costs and implementation complexity can increase as a business adopts more advanced features. A small store that only needs basic newsletters and abandoned-cart reminders may find the platform unnecessarily extensive.
Best for: Larger ecommerce businesses, B2B retailers, and stores with complex CRM and customer relationship requirements.
12. Shopify Email
Shopify Email is Shopify’s built-in email marketing solution. It is designed to help merchants create and send campaigns from within the Shopify ecosystem, making it a convenient starting point for stores that already use the platform.
Because it is closely connected to the Shopify administration environment, merchants can manage many email activities without adopting a separate marketing platform immediately.
Key Features
Shopify Email supports email campaign creation, templates, audience targeting, and campaign reporting. Its integration with Shopify allows merchants to use store information when preparing relevant marketing communications.
A small apparel store could send announcements about new collections, promote seasonal sales, and highlight products from its catalog.
The merchant can also use customer information available in Shopify to organize marketing audiences and improve campaign relevance.
Advantages
The biggest advantage is convenience. Shopify merchants can manage email campaigns alongside products, orders, and other store operations. This can reduce the number of systems a small business must learn.
It may be sufficient for stores that are building their first subscriber list and do not yet need complex workflows.
Limitations
Retailers with advanced segmentation, sophisticated customer lifecycle automation, or complex multichannel marketing requirements may eventually need a dedicated ecommerce marketing platform.
Availability, sending allowances, and charges should be checked against Shopify’s current terms.
Best for: New and small Shopify stores that want a simple way to start email marketing.
13. Sender
Sender is an email marketing and automation platform that can appeal to smaller businesses looking for accessible campaign creation and subscriber management.
For online stores, it can support promotional newsletters, new-product announcements, subscriber acquisition, and automated follow-up campaigns, subject to the integrations and features available on the selected plan.
Key Features
Sender offers email design tools, list management, segmentation, automation workflows, signup forms, and campaign analytics. Ecommerce integrations can help retailers connect marketing activity with their online shops.
A small store selling home accessories could use a signup form to collect subscribers and send a welcome sequence introducing its product range. The store could later distribute seasonal offers and product-care tips to relevant audiences.
Advantages
Sender can be attractive to businesses that want to begin email marketing without adopting an extensive enterprise marketing suite. Its campaign and automation tools can help small teams maintain regular communication with customers.
Limitations
The depth of store-specific automation, integrations, and reporting should be evaluated carefully. Retailers should test whether the platform can access the purchase and browsing events needed for their marketing strategy.
Best for: Budget-conscious startups and small ecommerce businesses that need practical email campaigns and basic automation.
14. Moosend
Moosend is an email marketing and automation platform designed to help businesses create campaigns, segment subscribers, and develop automated customer journeys. It can serve ecommerce businesses that want to improve customer engagement without implementing a large marketing technology stack.
Its automation features can help stores send messages based on subscriber activity and other supported events.
Key Features
Moosend offers email templates, campaign analytics, audience segmentation, marketing automation, and ecommerce-related functionality through supported integrations and plans.
For example, a pet supplies retailer could create a sequence for customers who purchase particular products. Buyers of pet food might receive feeding guidance and replenishment reminders, while customers who purchase toys could receive recommendations for related accessories.
The store could also send re-engagement messages to subscribers who have stopped interacting with its campaigns.
Advantages
Moosend can help small and medium-sized retailers build repeatable marketing workflows. Its automation capabilities may reduce the amount of manual work involved in delivering relevant communications.
Limitations
The suitability of its ecommerce integrations should be checked before implementation. Retailers that require advanced predictive customer analytics or extensive multichannel functionality may need a more specialized platform.
Best for: Small and medium-sized online stores that want email automation, segmentation, and campaign reporting.
15. Omnisend’s Shopify Alternative: Seguno
Seguno is a Shopify-focused email marketing application designed for merchants who prefer to manage campaigns from within the Shopify environment.
Rather than adopting a broad marketing suite, a retailer can use a Shopify-oriented application to manage promotional emails and selected automated communications close to its product catalog and store administration.
Key Features
Seguno provides Shopify-centered email marketing features, campaign templates, and automation options designed for merchants using that ecommerce platform. Exact capabilities depend on the current app version and subscription.
A small Shopify store selling handmade jewelry could use the application to announce new collections, highlight seasonal products, and communicate with customers about relevant offers.
The merchant may find this approach convenient because much of the marketing process remains within the Shopify workflow.
Advantages
Seguno is useful for merchants who value a close connection with Shopify and want to keep their marketing setup relatively simple. A store with straightforward promotional needs may not require the advanced analytics and multichannel features of a larger platform.
Limitations
Its Shopify focus means that it is not the natural choice for retailers operating primarily on WooCommerce, BigCommerce, or a custom ecommerce system. Businesses should compare its automation depth and reporting with other Shopify-compatible platforms as their requirements grow.
Best for: Shopify merchants who prefer an integrated, Shopify-centered approach to email marketing.
How to Choose the Best Email Marketing Tool for Your Online Store
Selecting an email marketing platform should begin with the needs of the business rather than the number of features advertised by a software provider. A tool that works well for a small store may not suit a retailer managing thousands of products and a large customer database.
1. Consider Your Ecommerce Platform
First, check whether the email marketing tool integrates with the platform powering your store. Shopify merchants can consider Shopify Email, Seguno, Klaviyo, Omnisend, and other compatible applications. WooCommerce retailers should confirm that their chosen platform can synchronize customer, order, and product information appropriately.
A connection that only transfers email addresses may be insufficient if the store intends to automate campaigns according to purchases, abandoned carts, or product views.
2. Evaluate Automation Features
Automation is one of the most important considerations for online stores. Instead of manually preparing every campaign, retailers can create workflows that respond to customer behavior.
Useful automations include welcome emails, abandoned-cart reminders, post-purchase follow-ups, review requests, product recommendations, replenishment reminders, and win-back campaigns.
A store does not need to launch every workflow immediately. It can begin with a welcome sequence and abandoned-cart recovery, then add more advanced journeys after reviewing customer behavior and campaign results.
3. Compare Pricing Structures
Email marketing providers use different pricing models. Some charge according to the number of contacts, while others emphasize monthly email volume or combine several limits.
A store should calculate its likely costs based on its active subscriber count, monthly sending requirements, automation needs, and any additional SMS usage. It should also examine whether unsubscribed contacts count toward billing and whether prices change significantly as the audience grows.
The lowest advertised starting price is not necessarily the least expensive option for a growing business.
4. Examine Segmentation and Personalization
Segmentation allows retailers to send different messages to customers with different interests and purchasing histories.
For example, a sports equipment store could separate customers interested in running, cycling, and strength training. Each group could receive product recommendations and educational content relevant to its interests.
Useful segmentation criteria include purchase history, product category, order value, engagement, location where appropriate, and time since the last purchase.
Personalization should be helpful rather than intrusive. Retailers should use customer data responsibly and provide clear ways for subscribers to manage their preferences.
5. Check Analytics and Revenue Attribution
A good email marketing tool should help the business understand how campaigns perform. Important measurements include delivery rate, bounce rate, click-through rate, conversion rate, unsubscribe rate, and revenue associated with campaigns or automated flows.
Revenue attribution should be interpreted carefully because a purchase may involve several marketing touchpoints. A campaign receiving credit for a sale does not necessarily mean it was the only factor that influenced the customer’s decision.
Retailers should combine platform reporting with ecommerce analytics and controlled experiments where possible.
6. Protect Email Deliverability
Even a well-designed campaign is ineffective if it does not reach subscribers’ inboxes. Stores should authenticate their sending domains using the appropriate SPF, DKIM, and DMARC configuration, maintain clean subscriber lists, and avoid sending unsolicited messages.
New subscribers should understand what they are signing up to receive. Retailers should also remove invalid addresses, honor unsubscribe requests promptly, and monitor bounce and complaint rates.
A legitimate, permission-based list is generally more valuable than a large database of contacts who have never agreed to receive marketing messages.
7. Plan for Future Growth
The platform should support the store’s expected development over the next year or two. A new retailer might begin with basic newsletters, but later require advanced segmentation, SMS, loyalty integration, subscription marketing, or deeper customer analytics.
Choosing a platform that can accommodate realistic growth may reduce the need for a disruptive migration. However, paying for enterprise-level functionality long before it is needed can waste limited marketing resources.
Email Marketing Strategies Every Online Store Should Use
Choosing the right tool is only the beginning. Results depend on the relevance of the messages, the quality of the subscriber list, and the way campaigns are organized.
Welcome Email Series
A welcome series introduces new subscribers to the store. It can explain what makes the business different, highlight popular products, answer common questions, and provide a first-purchase incentive when appropriate.
Rather than sending a long sequence of generic promotions, retailers should make each message useful and give subscribers a clear reason to explore the store.
Abandoned-Cart Recovery
Some shoppers add products to their carts but leave before completing their purchases. A carefully designed recovery sequence can remind them about the products and help resolve common concerns.
The message might summarize the cart, link back to checkout, and provide support information. Discounts should be tested rather than offered automatically to every shopper, since repeated incentives can reduce margins and train customers to wait for sales.
Post-Purchase Follow-Up
The relationship should not end when a customer completes an order. Post-purchase emails can provide product instructions, explain care requirements, request feedback, or recommend complementary products.
For example, a customer who buys a digital camera might benefit from a guide to memory cards, lenses, and camera maintenance. Recommendations should be relevant and should not interfere with essential order communications.
Customer Win-Back Campaigns
Retailers can identify customers who have not purchased for a defined period and send appropriate re-engagement messages. The timing should reflect the product’s normal buying cycle. A grocery or personal-care store may have a shorter replenishment window than a furniture retailer.
A win-back campaign could include new product announcements, helpful content, or a relevant incentive. Customers who remain inactive should not receive unlimited repetitive messages.
Seasonal and Promotional Campaigns
Seasonal promotions can help stores connect products with occasions such as holidays, back-to-school periods, summer activities, or end-of-season sales.
Campaigns should be planned around customer needs and inventory rather than simply increasing sending frequency. Clear subject lines, accurate offers, mobile-friendly design, and straightforward calls to action help customers understand the message.
Common Mistakes to Avoid
Online stores sometimes focus too heavily on subscriber growth while neglecting list quality and customer experience. Purchasing email lists, sending messages without appropriate permission, and ignoring unsubscribe requests can damage deliverability and create legal or compliance risks.
Another mistake is sending every campaign to the entire database. Customers have different interests, purchasing histories, and engagement levels. Thoughtful segmentation can make messages more relevant and reduce unnecessary sending.
Retailers should also avoid measuring success through open rates alone. Privacy protections and automated email activity can make open-rate figures less reliable. Clicks, conversions, orders, revenue, unsubscribes, and profit provide a broader picture of performance.
Finally, businesses should not assume that automation guarantees sales. A poorly timed message, irrelevant product recommendation, or excessive sequence can frustrate customers. Every workflow should be tested and reviewed regularly.
Frequently Asked Questions
What is the best email marketing tool for online stores?
Klaviyo is a strong option for retailers that need advanced ecommerce segmentation and customer behavior analysis. Omnisend is worth considering for stores that want email and SMS automation together. Shopify Email and Seguno are convenient options for Shopify merchants with simpler requirements, while Brevo may appeal to businesses comparing sending-based pricing.
The best choice depends on the store’s ecommerce platform, budget, list size, and automation needs.
Which email marketing tool is best for beginners?
MailerLite, Shopify Email, Mailchimp, and Sender are worth evaluating for beginners. Their campaign creation and subscriber management features can help a new retailer establish an email marketing routine without implementing an overly complex system.
A beginner should prioritize ease of use, reliable integrations, list management, and the ability to create a welcome sequence.
Can email marketing recover abandoned carts?
Yes. Many ecommerce email marketing platforms support abandoned-cart workflows when connected to a compatible store. These workflows can remind shoppers about products left in their carts and direct them back to checkout.
Results vary according to the product, price, customer intent, timing, and quality of the message. Recovery emails should comply with applicable privacy, marketing, and consent requirements.
How often should an online store send marketing emails?
There is no universal ideal frequency. A store may send weekly newsletters, occasional product announcements, and automated messages triggered by customer activity. The appropriate schedule depends on the buying cycle, subscriber expectations, and the value of each message.
Retailers should monitor engagement, complaints, and unsubscribes and allow customers to manage their preferences.
Is email marketing still worthwhile for ecommerce?
Email marketing remains useful because it provides a direct communication channel for customer education, repeat purchases, product launches, and customer retention. Its value depends on the quality of the subscriber list, the relevance of the campaigns, and the store’s ability to measure business outcomes.
Email works best as part of a broader strategy that includes product quality, customer service, website usability, search visibility, and other suitable marketing channels.
Conclusion
The best email marketing tools for online stores help retailers build relationships with customers, automate repetitive tasks, and communicate with subscribers at relevant moments in the buying journey.
Klaviyo and Omnisend are strong candidates for ecommerce-focused automation. Mailchimp and Brevo provide broader marketing options, while MailerLite, Sender, and AWeber can suit smaller businesses with simpler requirements. ActiveCampaign and HubSpot may be more appropriate when customer relationship management and advanced workflows are central to the business. Shopify Email and Seguno are especially relevant to merchants operating within Shopify.
Before choosing a platform, confirm its integration with your store, compare the full cost of the plan you need, and evaluate the automations and reporting features that matter most. Start with a few high-value workflows, measure the results, and improve them over time.
A successful ecommerce email strategy is not about sending the greatest number of messages. It is about delivering useful, relevant communication that helps customers make informed purchases and gives them good reasons to return.
Top 15 Email Marketing Tools for Online Stores: Case Studies and Comments
Email marketing can help online stores attract new customers, recover abandoned shopping carts, increase repeat purchases, and build long-term customer relationships. However, the results depend on more than the email marketing platform itself. Businesses must choose the right tool, connect it properly to their ecommerce store, develop relevant campaigns, and measure whether those campaigns contribute to profitable sales.
The following case studies and comments examine 15 email marketing tools commonly considered by ecommerce businesses. The examples explain how each platform could be used in a practical retail situation, what benefits a store might expect, and what limitations business owners should consider.
Case study note: The scenarios below are illustrative examples created to demonstrate possible strategies. They are not presented as verified customer testimonials or guaranteed performance results. Any numerical targets are planning examples rather than reported outcomes.
1. Klaviyo: Improving Customer Segmentation and Repeat Purchases
Case Study: A Fashion Store Personalizes Its Marketing
Imagine an online fashion retailer selling shoes, dresses, handbags, and accessories. The business has developed a sizable subscriber list, but its marketing team sends almost every promotion to the same audience. Customers receive irrelevant product recommendations, and many stop engaging with the emails.
The retailer introduces Klaviyo and connects it to its ecommerce store. It begins segmenting customers according to purchase history, browsing activity, product preferences, and engagement.
Customers who purchase shoes receive recommendations for complementary accessories. Shoppers who browse dresses but do not buy can receive relevant product highlights. Previous customers who have not returned for several months enter a re-engagement sequence.
The store also establishes welcome emails and abandoned-cart reminders. Rather than relying exclusively on discounts, it tests product education, customer reviews, and styling suggestions.
Over time, the marketing team compares the performance of segmented campaigns with its previous general promotions. It evaluates completed purchases, revenue, unsubscribe rates, and the profitability of incentives.
Results the Store Should Measure
The retailer should look for improvements in campaign relevance, repeat purchase rates, abandoned-cart recovery, and revenue per recipient. It should also measure the additional costs of the platform and any promotional discounts.
Comment
Klaviyo is particularly suitable for retailers that want to use detailed customer data to personalize marketing. Its strengths become more valuable when the store has enough customer activity to support meaningful segmentation.
However, advanced features do not automatically produce better results. Poorly configured integrations, inaccurate product data, and excessive messaging can undermine performance. Smaller stores should determine whether the additional functionality justifies the cost before adopting a complex setup.
2. Omnisend: Combining Email and SMS Campaigns
Case Study: A Beauty Store Builds an Abandoned-Cart Strategy
Consider an online beauty retailer that sells skincare products, cleansers, moisturizers, and cosmetic accessories. The store receives regular traffic, but a significant number of visitors leave without completing checkout.
The business uses Omnisend to establish an automated abandoned-cart workflow. A shopper who abandons a cart may receive an email reminding them of the selected products. A later message can answer common purchasing questions or highlight useful product information.
Where the shopper has separately provided appropriate consent and the store’s messaging practices comply with applicable requirements, the retailer can also test SMS reminders.
The business separates new subscribers from returning customers and uses different messages for each group. New subscribers receive an introduction to the brand, while returning customers may receive relevant product suggestions.
Results the Store Should Measure
The retailer tracks recovered orders, completed checkouts, email and SMS costs, unsubscribe rates, and customer complaints. It also compares email-only campaigns with coordinated email and SMS workflows.
The purpose is to determine whether the additional channel produces enough incremental value to justify its cost.
Comment
Omnisend is a useful option for online stores that want ecommerce-focused automation across email and other supported channels. It can simplify campaign management for teams that would otherwise maintain separate systems.
Nevertheless, using more channels is not automatically better. Retailers should reserve SMS for situations where immediacy adds value and should avoid sending repeated reminders that make customers feel pressured.
3. Mailchimp: Organizing Promotions and Customer Newsletters
Case Study: A Home Decor Store Creates a Consistent Newsletter
An online home decor business sells cushions, lamps, wall art, furniture accessories, and decorative products. Its marketing activities are irregular. The store sends emails mainly during major sales events and misses opportunities to educate subscribers about its products.
The retailer adopts Mailchimp to establish a consistent newsletter schedule. Each month, it plans campaigns featuring new arrivals, room-design ideas, seasonal collections, and selected promotions.
The business organizes subscribers into groups based on their interests and previous purchases, using the information available through its ecommerce integration. Customers interested in bedroom accessories receive different recommendations from those interested in living-room decor.
The retailer also tests subject lines, calls to action, and product layouts to discover which formats encourage meaningful engagement.
Results the Store Should Measure
The business reviews click-through rates, sales generated by campaigns, repeat purchases, unsubscribe rates, and the performance of different product categories.
It also evaluates whether a consistent schedule produces stronger engagement than occasional promotional messages.
Comment
Mailchimp can work well for stores that need email marketing alongside broader marketing activities, including content distribution and audience development.
Its usefulness depends on the ecommerce integration and features available under the chosen plan. Businesses that require advanced purchase-based automation should compare its capabilities with dedicated ecommerce marketing platforms before making a long-term decision.
4. Brevo: Managing Marketing Within a Controlled Budget
Case Study: A Small Electronics Store Improves Customer Communication
A small online electronics retailer sells headphones, keyboards, charging accessories, and computer peripherals. The business has collected a large number of customer email addresses, but its marketing budget is limited.
Instead of investing immediately in an extensive ecommerce marketing suite, the retailer evaluates Brevo’s pricing model and email sending allowances. It uses the platform to distribute product announcements, promotional newsletters, and educational content.
The store also examines whether its integration supports the customer events needed for automated purchase follow-ups and abandoned-cart reminders.
Transactional messages, such as order confirmations and delivery notifications, are organized separately from promotional campaigns so that essential customer communications remain clear.
Results the Store Should Measure
The retailer monitors total email marketing expenditure, campaign engagement, sales attributed to promotions, delivery performance, and the time spent managing its campaigns.
It compares these costs with the value generated by the email channel rather than judging success solely by subscriber growth.

Brevo may appeal to businesses that want email marketing, automation, and additional communication capabilities within one broader platform. Its pricing structure can be attractive to some businesses with large contact lists.
However, the store should calculate its actual costs using expected sending volume, plan limits, and any additional services. It should also confirm that the required ecommerce triggers and reporting functions are available.
5. MailerLite: Building a Subscriber List for a Handmade Products Store
Case Study: A Handmade Candle Business Develops Email Marketing
A small business sells handmade candles, gift boxes, and home fragrance products. Most of its customers discover the store through social media, but many visitors leave the website without purchasing.
The owner uses MailerLite to create a signup form offering subscribers a helpful candle-care guide. The form explains what subscribers can expect from the newsletter and allows them to sign up voluntarily.
New subscribers receive a welcome series introducing the brand, explaining its ingredients, and highlighting popular products. Later newsletters feature seasonal scents, gift recommendations, and product-care advice.
The owner monitors which topics attract clicks and uses those findings to improve future campaigns.
Results the Store Should Measure
The business tracks new subscribers, first purchases from email subscribers, repeat orders, newsletter engagement, and the cost of any incentives.
It also evaluates whether the signup form attracts people who are genuinely interested in its products.
Comment
MailerLite can be an accessible starting point for small retailers that need newsletters, signup forms, and straightforward automation. It is particularly useful when a store wants to combine product promotion with educational content.
A business with more sophisticated purchase-based segmentation may eventually require a different platform. Before choosing a plan, the owner should confirm the ecommerce integration and automation capabilities needed for the store’s strategy.
6. ActiveCampaign: Automating a Complex Customer Journey
Case Study: A Premium Coffee Equipment Retailer Encourages Repeat Sales
An online store sells espresso machines, grinders, coffee scales, filters, and maintenance accessories. Some customers make a single purchase, while others gradually build a collection of related products.
The retailer uses ActiveCampaign to create customer journeys based on purchase history and engagement. A customer who buys an espresso machine receives setup guidance and maintenance information. After an appropriate interval, the store can recommend compatible accessories.
Customers who purchase grinders receive different educational content from customers who buy coffee-making accessories.
If the business also operates a sales team or handles high-value commercial orders, its CRM features may help coordinate follow-ups with potential buyers.
Results the Store Should Measure
The retailer evaluates repeat purchase rates, accessory sales, engagement with educational content, customer retention, and the additional cost of maintaining its automation system.
It also checks whether automated messages generate useful sales without overwhelming customers with recommendations.
Comment
ActiveCampaign is worth considering when an online store needs detailed automation and customer relationship management. It can be especially useful for products with longer consideration periods or multiple opportunities for follow-up sales.
For a small shop that only sends weekly promotions, its wider feature set may be unnecessary. Implementation should begin with a few well-defined customer journeys rather than a large number of complicated workflows.
7. Drip: Creating Behavior-Based Customer Campaigns
Case Study: A Direct-to-Consumer Pet Supplies Brand Builds Retention
A pet supplies retailer sells food, toys, grooming products, and accessories. The company wants to encourage repeat purchases without sending every customer the same offers.
The business uses Drip to develop customer segments based on supported ecommerce events and purchase information. Customers who purchase a particular category receive relevant product education and recommendations.
For products with predictable replenishment cycles, the store tests reminder emails timed around the customer’s likely need to reorder. Buyers of toys and accessories receive a different type of follow-up.
The marketing team also identifies inactive customers and develops re-engagement campaigns featuring useful information or relevant new products.
Results the Store Should Measure
The business monitors repeat orders, time between purchases, revenue per customer, unsubscribe rates, and the performance of replenishment reminders.
It should compare customers who receive the automated messages with an appropriate comparison group where practical, helping determine whether the campaigns influence additional purchases.
Comment
Drip is relevant to ecommerce brands that want behavior-based marketing and customer lifecycle automation. It can help retailers create more targeted campaigns than a basic newsletter system.
The platform’s value depends on how well its integrations capture relevant customer activity. Retailers should also avoid assuming that every product has a predictable reorder cycle; reminder timing should reflect actual customer behavior.
8. GetResponse: Combining Product Sales With Educational Marketing
Case Study: A Fitness Equipment Store Uses a Lead Magnet
An online fitness retailer sells resistance bands, yoga mats, adjustable weights, and home workout accessories. The business wants to attract subscribers who are interested in fitness but may not be ready to purchase immediately.
The store creates a beginner’s home-workout guide and promotes it through its website. Visitors can subscribe to receive the guide and additional fitness content.
GetResponse supports the business’s signup process and email sequence. New subscribers receive useful workout advice, followed by product recommendations related to the equipment discussed in the content.
The retailer tests different calls to action and ensures that promotional messages remain relevant to subscribers’ stated interests.
Results the Store Should Measure
The business evaluates subscriber acquisition costs, guide downloads, email engagement, product page visits, and purchases generated by the sequence.
It also measures whether subscribers acquired through educational content become repeat customers over time.
Comment
GetResponse can be a good fit for retailers that combine ecommerce with landing pages, lead generation, and content marketing.
However, stores should verify the platform’s compatibility with their ecommerce systems and the specific purchase-triggered workflows they require. A lead-generation tool is not automatically the best option for every advanced retail automation need.
9. AWeber: Supporting a Specialty Gardening Store
Case Study: A Gardening Retailer Builds Seasonal Campaigns
An online gardening store sells seeds, planters, soil products, gardening tools, and plant-care accessories. Its sales fluctuate throughout the year, and customers often need advice about what to buy during different growing seasons.
The retailer uses AWeber to maintain a newsletter featuring seasonal planting tips, gardening advice, product announcements, and promotional offers.
Subscribers receive information relevant to the season and the store’s product range. The business also creates targeted messages for customers who express interest in indoor plants, vegetable gardens, or outdoor landscaping.
Results the Store Should Measure
The retailer tracks newsletter engagement, product clicks, seasonal revenue, subscriber growth, and repeat purchases.
It can also compare the performance of educational newsletters with campaigns focused primarily on discounts.
Comment
AWeber can suit small stores that value newsletters, subscriber management, and straightforward email communication.
Its suitability for more advanced ecommerce workflows depends on the available integrations and plan features. Retailers should assess whether it can access enough purchase data to support their intended personalization strategy.
10. Constant Contact: Connecting Online Sales With Local Retail Activities
Case Study: A Gift Shop Coordinates Online and In-Store Promotions
A gift shop sells products through an ecommerce website and a physical retail location. The business organizes seasonal displays, local events, and holiday promotions, but its online and offline marketing activities are often disconnected.
The retailer uses Constant Contact to plan newsletters that announce new gift collections, promote upcoming events, and highlight seasonal products.
Customers can receive information relevant to their interests, while local subscribers may receive invitations to events when they have agreed to receive those communications.
The store also tests whether event-related emails lead to online purchases, in-store visits, or both.
Results the Store Should Measure
The business evaluates campaign clicks, online orders, event registrations, redemption of promotional offers, and repeat customer activity.
It should use suitable tracking methods to distinguish online sales from in-store results wherever possible.
Comment
Constant Contact can be useful for smaller retailers that combine online selling with local events and community marketing.
Businesses requiring detailed purchase-event automation or sophisticated ecommerce analytics should compare it with platforms built specifically around online retail. The most suitable tool is the one that supports the store’s actual sales model.
11. HubSpot Marketing Hub: Managing High-Value Customer Relationships
Case Study: A Commercial Furniture Store Nurtures Business Buyers
An online furniture retailer sells desks, office chairs, meeting tables, and storage products to individuals and organizations. Some customers purchase immediately, while corporate buyers may request quotations and require several conversations before placing an order.
The business uses HubSpot Marketing Hub to coordinate marketing communications with customer records. Potential business buyers receive relevant product information, buying guides, and updates related to their interests.
The CRM can help the sales team understand previous interactions and coordinate follow-ups. Existing customers may receive information about complementary products or future office requirements.
Results the Store Should Measure
The retailer monitors qualified leads, quotation requests, sales conversions, order value, customer retention, and the cost of managing its marketing and CRM systems.
It should distinguish between email activity that supports a sale and activity that directly generates a measurable conversion.
Comment
HubSpot Marketing Hub is worth evaluating when customer relationship management is as important as promotional email. It can be useful for retailers with complex sales processes, wholesale customers, or several teams interacting with the same buyers.
For a small business with straightforward online checkout, the platform’s broader capabilities may introduce unnecessary expense and complexity.
12. Shopify Email: Starting With Built-In Ecommerce Marketing
Case Study: A New Shopify Store Launches Its First Campaigns
A new Shopify store sells clothing and accessories. The owner is learning ecommerce operations and does not yet have a large marketing budget.
Instead of immediately adopting a separate advanced marketing platform, the owner evaluates Shopify Email and begins with a basic newsletter strategy.
The store collects subscriber consent through its website and sends a welcome message, announcements about new products, and occasional promotional campaigns. The owner also reviews Shopify’s available customer information to organize audiences appropriately.
As the store grows, the owner assesses whether more advanced automation and segmentation are necessary.
Results the Store Should Measure
The business tracks email subscribers, campaign clicks, orders associated with campaigns, repeat purchases, and the time needed to manage marketing.
It also reviews whether its initial setup is sufficient for its current size before committing to additional software.
Comment
Shopify Email is a sensible starting point for many merchants already using Shopify. Keeping campaigns close to the store’s administration can reduce the learning curve and simplify day-to-day operations.
However, retailers should not assume that a built-in tool will satisfy every future requirement. If the store develops complex customer journeys or needs deeper behavioral reporting, it can compare specialist platforms as its needs evolve.
13. Sender: Running Affordable Promotional Campaigns
Case Study: A Small Home Accessories Store Improves Its Newsletter Process
A small ecommerce business sells storage baskets, kitchen accessories, decorative items, and practical household products. The owner currently prepares promotional emails manually and has difficulty maintaining a consistent schedule.
The business evaluates Sender for campaign design, subscriber management, and automation. It develops a monthly calendar with product highlights, seasonal buying ideas, and occasional special offers.
The owner organizes subscribers into relevant groups when sufficient preference or purchase information is available. Rather than sending every promotion to everyone, the store prioritizes products likely to interest each audience.
Results the Store Should Measure
The business monitors campaign engagement, sales generated by email, unsubscribe rates, sending costs, and the time saved through reusable templates and automation.
The owner also checks whether the platform’s ecommerce integration provides the information required for more targeted campaigns.
Comment
Sender can be worth considering for budget-conscious retailers that need practical email campaigns without adopting a large marketing suite.
Before choosing it, businesses should confirm current plan limits, ecommerce compatibility, automation options, and reporting depth. The platform should fit the store’s needs today while leaving room for reasonable growth.
14. Moosend: Improving Product Recommendations and Re-Engagement
Case Study: A Specialty Food Store Encourages Repeat Orders
An online specialty food store sells gift hampers, sauces, snacks, and regional products. Some customers place one order for a special occasion, while others return throughout the year.
The retailer uses Moosend and its supported integrations to organize subscribers and develop automated communications. Customers receive product updates based on their interests and purchasing history where that data is available.
The store also creates seasonal campaigns featuring gift hampers and special collections. Inactive customers may receive a carefully timed message highlighting new products or offering helpful suggestions.
Results the Store Should Measure
The retailer reviews repeat purchase rates, campaign-attributed sales, customer engagement, and the performance of different product categories.
It should also measure the margin earned from additional orders rather than assuming that higher sales volume necessarily means greater profit.
Comment
Moosend can be suitable for businesses seeking email automation, segmentation, and campaign analytics in one platform.
Its suitability depends on the ecommerce integration and the sophistication of the workflows required. Stores with highly specialized predictive analytics or multichannel needs should compare it against more ecommerce-focused alternatives.
15. Seguno: Keeping Shopify Email Marketing Close to the Store
Case Study: A Jewelry Brand Promotes New Collections
A small Shopify jewelry store sells necklaces, bracelets, earrings, and personalized gifts. New collections are released several times each year, and the owner wants to promote them without building an overly complicated marketing system.
The store evaluates Seguno, a Shopify-focused email marketing application. It uses supported campaign tools to announce new products, highlight gift collections, and communicate with subscribers.
The owner also reviews the available automation features for welcoming subscribers and following up with customers. The campaigns are planned around product launches and seasonal buying periods rather than sending messages without a clear purpose.
Results the Store Should Measure
The retailer evaluates campaign engagement, product clicks, purchases following launches, repeat orders, and the time spent managing email promotions.
It also compares the cost and functionality of Seguno with other Shopify-compatible platforms as the customer database expands.
Comment
Seguno can be attractive to Shopify merchants who prefer a store-centered marketing workflow. Its Shopify focus may help keep routine campaign tasks relatively straightforward.
Retailers using other ecommerce platforms should investigate alternatives. Shopify merchants should also compare the application’s current automation, reporting, and pricing with their projected requirements before choosing it for the long term.
Comparative Lessons From the 15 Case Studies
The examples demonstrate that email marketing platforms solve different problems. Some emphasize detailed ecommerce customer data, others prioritize multichannel communication, and some offer simpler campaign tools for businesses with limited resources.
| Business requirement | Tools worth evaluating | Main consideration |
|---|---|---|
| Advanced ecommerce segmentation | Klaviyo, Drip | Purchase data and behavioral triggers |
| Email combined with SMS | Omnisend, Brevo | Channel costs and customer consent |
| General newsletters and promotions | Mailchimp, MailerLite, AWeber | Ease of use and audience management |
| CRM and complex customer journeys | ActiveCampaign, HubSpot Marketing Hub | Workflow complexity and total cost |
| Landing pages and lead generation | GetResponse, MailerLite | Subscriber acquisition and conversion |
| Shopify-centered email campaigns | Shopify Email, Seguno | Integration and future scalability |
| Budget-conscious campaigns | Brevo, Sender, Moosend | Sending limits and available automation |
| Online and local retail promotion | Constant Contact | Coordination of digital and physical activities |
These categories are starting points rather than strict rankings. A platform may support several of these requirements, and the best fit depends on the specific plan and integrations available.
Practical Recommendations for Online Store Owners
Start With Three Essential Automations
Many stores benefit from beginning with a welcome sequence, abandoned-cart reminders, and post-purchase follow-ups. These workflows address important moments in the customer journey and provide a manageable starting point for a small marketing team.
After measuring their performance, the business can add win-back campaigns, replenishment reminders, and product recommendations where appropriate.
Measure Profitability, Not Just Email Revenue
A campaign may generate orders but still be unprofitable if it depends on excessive discounts or expensive customer acquisition. Store owners should consider product margins, promotional costs, software fees, and other relevant expenses.
Revenue attribution should also be interpreted carefully. An email may contribute to a purchase without being the only reason it happened. Comparing campaign performance over time and using controlled tests where practical can improve decision-making.
Maintain a Healthy Subscriber List
Stores should collect email addresses transparently and use them according to the consent and marketing rules that apply to their customers. They should remove invalid addresses, honor unsubscribe requests, and avoid purchasing lists.
A smaller list of engaged subscribers can be more valuable than a much larger list of people who do not expect or want the messages.
Test Before Scaling
Businesses should test email rendering on mobile devices, verify links, check product availability, confirm discount conditions, and review automated workflows before launching them widely.
Subject lines, calls to action, sending times, and offers can be tested systematically. Changes should be based on measured results rather than assumptions about what customers prefer.
Final Comments
Email marketing is most effective when it supports a clear business objective. A store seeking to increase repeat purchases needs different workflows from a store focused on attracting first-time buyers. Likewise, a retailer with a small subscriber list may not benefit from the same level of automation as a brand managing a large volume of customer activity.
Klaviyo and Drip are worth considering for behavior-based ecommerce marketing. Omnisend can suit retailers that want to coordinate email and SMS, while Brevo may appeal to businesses balancing marketing needs with a limited budget. Mailchimp, MailerLite, Sender, AWeber, and Moosend can be useful for a range of campaign and automation requirements. ActiveCampaign and HubSpot Marketing Hub are relevant when customer relationship management is a priority. GetResponse supports broader lead-generation strategies, while Constant Contact can help businesses that combine online and offline retail. Shopify Email and Seguno offer Shopify-focused alternatives.
The most important decision is not simply which platform has the longest feature list. It is which tool connects reliably to the store, supports the customer journeys the business needs, fits its budget, and provides enough reporting to guide improvements.
Online retailers should start with a manageable strategy, measure the results, and expand automation as their customer base and marketing requirements grow. Consistent, relevant, permission-based communication is more valuable than sending large volumes of generic promotional emails.
