How to Use ChatGPT to Write Email Campaigns in Mailchimp: A Complete Step-by-Step Guide

Email marketing remains one of the most effective ways for businesses to communicate with customers, promote products, generate leads, and build long-term relationships. Whether you operate an online store, digital marketing agency, consulting business, educational institution, or software company, well-written email campaigns can help you reach your audience directly.

However, creating effective email campaigns takes time. Marketers must research topics, develop subject lines, write engaging messages, organize promotional content, create calls to action, and prepare follow-up emails. Managing these activities can become challenging when a business needs to send campaigns regularly.

This is where ChatGPT and Mailchimp can work together.

ChatGPT can help marketers brainstorm campaign ideas, write email copy, generate subject lines, improve existing messages, and develop complete email sequences. Mailchimp provides the tools to organize subscribers, design emails, schedule campaigns, automate communication, and measure results.

Although these platforms perform different functions, combining them creates a practical email marketing workflow. ChatGPT helps prepare the content, while Mailchimp helps manage and deliver the campaign.

This guide explains how to use ChatGPT to write email campaigns in Mailchimp, from preparing your marketing strategy to publishing, testing, and improving your emails.

Understanding How ChatGPT and Mailchimp Work Together

Before creating a campaign, it is important to understand the role of each platform.

ChatGPT is an AI assistant that can generate and improve written content based on instructions provided by the user. You can use it to develop campaign strategies, write promotional messages, create newsletters, suggest subject lines, and prepare follow-up sequences.

Mailchimp is an email marketing platform that helps businesses manage subscribers and distribute marketing messages.

A typical workflow looks like this:

1. Define your marketing objective.

2. Provide ChatGPT with information about your business and target audience.

3. Ask ChatGPT to generate the email campaign.

4. Review and edit the generated content.

5. Copy the approved content into Mailchimp.

6. Design the email using Mailchimp’s editor.

7. Select the appropriate subscriber audience.

8. Test the email before sending.

9. Schedule or send the campaign.

10. Review the results and improve future campaigns.

This approach reduces the amount of manual writing required while allowing marketers to retain control over campaign quality and delivery.

What Can ChatGPT Do for Mailchimp Email Campaigns?

ChatGPT can assist with several stages of email marketing. You do not need to use it only for writing the main email body.

1. Generate Email Campaign Ideas

One of the first challenges in email marketing is deciding what to communicate.

A business may have hundreds of subscribers but struggle to identify interesting topics for its next newsletter.

ChatGPT can help generate campaign ideas based on your industry, products, audience, and marketing objectives.

For example, an online clothing store might request ideas for:

• New product announcements.

• Seasonal clothing collections.

• Customer appreciation campaigns.

• Holiday promotions.

• Discount offers.

• Product-care advice.

• Style recommendations.

• Abandoned-cart reminders.

A software company might request ideas for product tutorials, feature announcements, customer onboarding, and educational newsletters.

2. Write Email Subject Lines

The subject line is one of the first things recipients see when an email arrives.

ChatGPT can generate multiple subject lines for the same campaign, allowing you to compare different approaches.

For example, if your business is promoting an email marketing service, ChatGPT might suggest:

• Improve Your Email Marketing Results With Smarter Tools

• Ready to Build a More Engaged Email List?

• Discover a Better Way to Manage Email Campaigns

• Make Your Next Email Campaign More Effective

You can then select the most relevant option or test different versions.

Avoid subject lines that make exaggerated promises or misrepresent the actual email content.

3. Write Complete Marketing Emails

ChatGPT can create the complete body of an email campaign, including the introduction, main message, product benefits, supporting information, and call to action.

You can specify the preferred length, tone, audience, and purpose.

For example, a business launching a new product could request a short promotional email that introduces the product, explains its main benefits, and invites subscribers to visit the website.

4. Rewrite and Improve Existing Emails

You may already have an email draft but need to improve its clarity, structure, or persuasive value.

ChatGPT can help you:

• Correct grammar and spelling.

• Remove unnecessary sentences.

• Simplify complicated explanations.

• Make the message more conversational.

• Improve the introduction.

• Strengthen the call to action.

• Adapt the content for different audiences.

This is useful when a marketing team wants to improve existing material without completely changing its message.

5. Create Email Sequences

ChatGPT can also prepare multiple emails that work together as part of a marketing sequence.

For example, a business could develop a five-message welcome series for new subscribers.

Each email would have a different purpose, such as introducing the company, providing useful information, explaining products, sharing customer experiences, and encouraging the subscriber to take the next step.

This content can then be configured as an automated journey in Mailchimp.

Step-by-Step: Writing an Email Campaign With ChatGPT and Publishing It in Mailchimp

The following example uses a fictional online business called BrightHome, which sells home office furniture in the United States. The company wants to promote a new collection of ergonomic office chairs to existing subscribers.

You can follow the same process for almost any business.

Step 1: Give ChatGPT Background Information About Your Business

Start by explaining what your company does, who your customers are, and what you want the campaign to achieve.

Do not simply ask ChatGPT to write an email without providing context. The quality of the output depends partly on the quality of the instructions.

For example, use this prompt:

ChatGPT can use this background to generate more relevant content than it would from a generic request.

You can reuse the business description in future conversations and update it whenever your products, audience, or marketing objectives change.

Step 2: Ask ChatGPT to Generate Campaign Subject Lines

Once ChatGPT understands your business, request several subject lines.

Use this prompt:

ChatGPT might suggest options such as:

1. Make Your Home Office More Comfortable

2. Discover Our New Ergonomic Chair Collection

3. A Better Seating Experience for Your Workday

4. New Office Chairs Designed for Everyday Comfort

5. Refresh Your Workspace With BrightHome

You can choose one for the first campaign and reserve other options for future testing.

Important: A subject line should describe what the subscriber will actually find inside the email. Avoid using false scarcity or claiming that a product is discounted when it is not.

Step 3: Ask ChatGPT to Write the Complete Email

Now request the main email content.

A possible result might look like this:

The draft is now ready for editing. Replace the fictional company details with your real business information and verify all product descriptions before publication.

Step 4: Improve the Email With Follow-Up Prompts

The first draft does not have to be the final version.

You can ask ChatGPT to revise specific sections without rewriting the entire email.

For example:

• “Make the introduction more engaging without increasing the length.”

• “Rewrite the second paragraph in simpler language.”

• “Make the call to action more specific.”

• “Reduce the promotional tone and make the message sound more natural.”

• “Create a shorter version suitable for mobile readers.”

• “Write three alternative closing paragraphs.”

This iterative approach allows you to refine the email until it matches your business’s communication style.

You can also ask ChatGPT to check the message for unsupported claims, confusing statements, and unnecessary repetition.

Step 5: Copy the Approved Content Into Mailchimp

Once you are satisfied with the email, open your Mailchimp account.

The standard workflow is:

1. Go to the Campaigns area.

2. Select the option to create an email campaign.

3. Choose the regular email campaign type.

4. Enter an internal campaign name.

5. Select the appropriate audience or subscriber segment.

6. Enter your sender name and verified sender email address.

7. Add the subject line and preview text generated with ChatGPT.

8. Open the email designer.

9. Choose a suitable template or layout.

10. Add the headline, body text, images, and call-to-action button.

Mailchimp’s campaign creation workflow includes recipient selection, sender details, subject information, email design, and a final review before sending. The exact interface can change as the platform updates its email builder.

An important distinction: In this basic workflow, you are copying approved content from ChatGPT into Mailchimp. You do not need a direct ChatGPT-to-Mailchimp integration to do this. If a supported integration is available on your account, it may provide additional ways to work across the services, but the copy-and-paste method is straightforward and works independently.

Step 6: Use ChatGPT to Prepare the Email Design

ChatGPT can also help you plan the structure of the email, even though the actual design and delivery happen in Mailchimp.

For example, ask:

“Suggest a clean Mailchimp email layout for a promotional campaign announcing a new collection of ergonomic office chairs. Include the order of the headline, hero image, introduction, product benefits, call-to-action button, and footer.”

A possible structure is:

In Mailchimp, recreate this structure using the available content blocks. Keep the design simple and make the main call to action easy to find.

Step 7: Add Images and Call-to-Action Buttons

An email campaign does not need to consist entirely of text.

Product images, banners, illustrations, and other relevant visual elements can help communicate the message.

For example, a clothing store could include product photographs, while a training institution might use an image illustrating its latest online course.

ChatGPT can help suggest suitable image concepts and write image descriptions, but you should use genuine product images or properly licensed visuals where appropriate.

The call-to-action button should tell recipients what to do next.

Examples include:

• Shop Now.

• Explore the Collection.

• Read the Full Guide.

• Register Today.

• View Available Courses.

• Book a Consultation.

Avoid using multiple competing buttons. One primary action is usually easier for subscribers to understand.

Step 8: Personalize the Email

ChatGPT can help you develop different versions of a campaign for different subscriber groups.

For example, a furniture retailer might want to send one message to customers who have purchased office desks and another to subscribers who have only browsed office chairs.

You can ask ChatGPT:

“Rewrite this promotional email for customers who previously purchased office desks. Explain how an ergonomic chair could complement their existing workspace. Keep the message helpful rather than overly promotional.”

Mailchimp can then use its audience and segmentation features to distribute the appropriate version to the relevant group.

You can also use Mailchimp merge tags to insert subscriber information, such as a first name, into an email. Test these fields carefully before sending because personalization errors can make a campaign look unprofessional.

Step 9: Ask ChatGPT to Create Follow-Up Emails

A single promotional email may not be enough to support a complete marketing campaign.

You can use ChatGPT to prepare a follow-up sequence.

For example:

These are suggested timings, not universal rules. Your actual schedule should reflect the campaign, audience expectations, and business results.

You can ask ChatGPT to write each email separately, ensuring that the messages do not simply repeat the same promotional content.

Mailchimp’s automation flows can be used to configure eligible customer journeys, triggers, delays, and follow-up messages.

How to Test and Improve Your ChatGPT-Written Campaign in Mailchimp

Creating an email is only part of the process. You also need to make sure that the message looks professional, reaches the intended audience, and encourages the desired action.

1. Send a Test Email

Before sending your campaign to subscribers, use Mailchimp’s test email option.

Send the message to yourself and, where appropriate, a colleague who can review it.

Check:

• Whether the subject line is correct.

• Whether the preview text displays properly.

• Whether the images load.

• Whether the buttons work.

• Whether the links lead to the correct pages.

• Whether the email displays properly on mobile devices.

• Whether the unsubscribe link and footer are present.

Pay particular attention to personalization fields. Some merge tags may not display correctly in ordinary test emails, so use Mailchimp’s preview options to inspect how they will appear for actual contacts.

2. Use ChatGPT to Generate A/B Testing Ideas

A/B testing involves comparing different versions of an email to determine which performs better.

ChatGPT can generate alternative versions of subject lines, introductions, calls to action, and email content.

For example, you could ask:

“Create two different subject lines for our BrightHome ergonomic office chair campaign. Version A should focus on workspace comfort, while Version B should focus on refreshing a home office. Keep both subject lines natural and concise.”

You might receive:

• Version A: Make Your Home Office More Comfortable

• Version B: Give Your Workspace a Fresh New Look

You can enter the alternatives into Mailchimp’s A/B testing workflow.

Mailchimp supports testing variables such as subject lines, sender names, email content, and sending times, subject to plan availability. Its documentation also explains how to choose the winning version based on campaign results.

A good starting point is to test one major variable at a time. This makes it easier to understand which change influenced the result.

3. Analyze the Campaign Results With ChatGPT

After the campaign has been sent, review its Mailchimp report.

You can use the results to understand:

• How many emails were delivered.

• How many messages bounced.

• How many subscribers clicked links.

• How many recipients unsubscribed.

• How many sales or registrations resulted from the campaign, if conversion tracking is configured.

You can then ask ChatGPT to help interpret the figures.

For example:

ChatGPT can calculate the rates and suggest areas to investigate. For example, it might recommend improving the landing page, reviewing the product offer, or making the call to action more prominent.

However, do not assume that a campaign report proves why someone did or did not purchase. Use the figures as evidence for further investigation.

Also remember that open rates can be affected by email privacy protections and automated activity. Clicks, conversions, and actual business outcomes often provide more useful performance information.

10 Useful ChatGPT Prompts for Writing Mailchimp Email Campaigns

You can save the following prompts and reuse them whenever you need to create a new campaign.

The prompts become more effective when you include your business name, audience, product information, campaign objective, and preferred tone.

Best Practices for Using ChatGPT With Mailchimp

1. Give ChatGPT Accurate Business Information

Do not expect AI to know the latest details about your products, prices, services, or promotional offers.

Provide verified information before requesting content.

For example, if you are advertising a product with a specific price, include that price in your prompt rather than expecting ChatGPT to invent or retrieve it.

2. Maintain a Consistent Brand Voice

Your subscribers should recognize your business through the way you communicate.

If your company uses a friendly and professional tone, maintain that style across newsletters, promotions, and follow-up messages.

You can ask ChatGPT to use your preferred writing style in every campaign.

3. Avoid Excessive Promotional Language

Not every email needs to sound like a sales advertisement.

Educational content, useful advice, product information, and customer updates can provide value without constantly asking subscribers to make a purchase.

A balanced email marketing strategy is generally more sustainable than sending repeated sales messages.

4. Do Not Send AI Content Without Reviewing It

AI can produce inaccurate information, unsupported claims, or wording that does not fit your business.

A human should approve the final email, especially when it contains financial information, health-related claims, legal statements, pricing, or time-sensitive offers.

5. Respect Subscriber Consent

Use Mailchimp to communicate with appropriately subscribed contacts and honor unsubscribe requests.

For US commercial email, the CAN-SPAM Act establishes requirements such as accurate sender information, non-deceptive subject lines, a valid postal address, and a functioning opt-out mechanism. Other countries may impose additional consent and privacy requirements.

Do not use ChatGPT to generate messages for unsolicited bulk emailing or to disguise the identity of the sender.

6. Keep Your Emails Short and Readable

Many subscribers read marketing messages on mobile devices.

Use short paragraphs, meaningful headings, clear buttons, and relevant images.

A long email is not automatically a better email. Focus on communicating the information the recipient needs.

7. Protect Customer Data

You do not need to provide ChatGPT with a complete subscriber database to write a campaign.

Use general audience descriptions rather than pasting customer names, email addresses, payment information, or other sensitive personal details into prompts.

Common Mistakes to Avoid

• Using generic prompts: A vague request often produces generic marketing copy. Provide business and audience information.

• Copying AI content without editing: Always check the wording, facts, and brand voice.

• Ignoring mobile design: Preview your campaign on different screen sizes.

• Using too many calls to action: Make the main action clear.

• Sending every campaign to everyone: Use relevant audience segments.

• Ignoring campaign reports: Review results and improve future emails.

• Repeating the same message: Give subscribers a reason to read each new campaign.

• Using misleading subject lines: Ensure that the subject accurately represents the email.

• Forgetting unsubscribe requirements: Keep your campaign compliant with applicable marketing laws and Mailchimp’s policies.
