Key Comparative Metrics
- According to a benchmark summary, email campaigns produced about 4.24% of visitors converting to purchase, compared with just 0.59% from social media. (Campaign Monitor)
- One source states that email subscribers are 6× more likely to click through than users on a tweet. (Campaign Monitor)
- Email marketing ROI often cited at ~$36 (or more) for every $1 spent, whereas social media returns are much lower (in the $2-$4 per $1 spent range). (artdigitalmedia.co.uk)
- Average click-through rate (CTR) benchmarks: one blog cites email CTR ~3.57%, whereas Facebook/Twitter in that context ~0.07% / ~0.03%. (Mailmunch)
- Organic reach: A blog reported that if you have 2,000 subscribers, roughly 435 might open an email, whereas only 120 of your Facebook fans might see the message and 40 on Twitter. (Mailmunch)
- From a large list of stats:
- “Email marketing drives more conversions than any other marketing channel …” (Campaign Monitor)
- “When it comes to purchases made as a result of receiving a marketing message, email has the highest conversion rate (66%), when compared to social, direct mail and more.” (Campaign Monitor)
Case Evidence & Context
- One article states:
“Email marketing and social media aren’t created equal. Email excels at converting existing customers… social media shines for brand awareness and reaching new audiences.” (EdgyMuse Marketing)
- Another discussion:
“Email marketing can be a powerful tool for driving conversions. The average email conversion rate is around 18%. … Social media marketing also plays a significant role but usually conversion rates of 1-2%.” (SassSolve)
- A blog comparing engagement and conversion:
“Based on this data, email still remains the most efficient channel for direct responses and conversions. On the other hand, social platforms show better results in awareness and fleeting engagement.” (Email: conversion ~6.05%, social media ~0.5-1%) (sendigram.com)
- Additional hiring/marketing commentary (from user communities) supports the idea that “email wins for actual sales, social media is mostly for reach” in practice. (Reddit)
Commentary & Insights
- Email’s strength lies in direct delivery (to inboxes) and opt-in audience — meaning the recipient has already expressed interest. That inherently boosts conversion potential.
- Social media excels at brand awareness, community building, and top-of-funnel reach, but tends to have lower conversion because many users are passive browsers, not actively seeking offers.
- One commentator:
“Email will almost always have a better ROI … because you’re reaching people who already showed interest in your brand.” (Mailmunch)
- The “owned audience” aspect: Your email list is owned by you (subscribers you collected); social media audiences are subject to algorithm changes, reach limitations, platform policy changes. This gives email a strategic advantage for conversions and long-term engagement.
- Nevertheless, social media still has value — but its role is more likely supportive (feed into email list, build brand, nurture) rather than as the primary channel for direct conversion.
Implications for Marketers
- If your goal is sales, direct conversions, revenue, email should be a top priority channel — not just an afterthought.
- Use social media to feed the top of the funnel: build awareness, capture interest, then move the audience into an email relationship where you can nurture and convert more effectively.
- Optimize your email programs: segmentation, personalization, strong subject lines, clear CTAs — because higher conversion and engagement depend on doing email well.
- Don’t neglect social media: it plays a different role (brand, community, reach) — but treat it accordingly rather than expecting same conversion levels as email.
- Measure properly: track conversion rates, revenue per subscriber, click-throughs, not just likes/shares. Compare channel results to understand ROI.
- Because email tends to outperform, budget and resources should reflect that: allocate enough to list building, email content, automation, testing.
- Here are several strong case studies and expert comments that demonstrate how email marketing continues to outperform social media platforms in both engagement and conversion rates.
Case Studies
Case Study 1: Reach & Click-through Comparison
From a recent article:
“If you have 2,000 subscribers, here’s how many people will see your message: Email: 435 opens; Facebook: 120 views; Twitter: 40 views.” (businessservicehub.com)
In the same article:
“Email marketing has an average CTR of 3.57%. Facebook’s engagement rate is 0.07%, and Twitter’s is 0.03%.” (Mailmunch)
Takeaway: The email channel offers far greater visibility and click-engagement than social media in comparable audience sizes.
Case Study 2: Conversion & ROI Metrics
From multiple sources:
- One source states: “Email marketing delivers $36 for every $1 spent, while social media yields just $2.80 for every $1 spent.” (The Harman Media & Marketing Group)
- Another indicates: “Email converts at ~4.29% vs social media ~1.81%.” (easydigilearn.com)
Takeaway: Email not only attracts more clicks, but those clicks more often convert into desired outcomes (sales, leads) and deliver stronger return on investment.
Case Study 3: Qualitative Feedback from Marketers
From Reddit commentary and practitioner forums:
“Email wins for actual sales … social is mostly vanity metrics for most SaaS companies.” (Reddit)
“While social media platforms are great for reach, email marketing continues to deliver the highest ROI… Unlike social algorithms that constantly change, email puts you in direct control of your audience.” (Reddit)
Takeaway: Marketers on the ground increasingly view social media as a top-of-funnel awareness tool, while email is where the “money happens”.
Expert Commentary & Insights
- From a comparative article:
“Email marketing is ideal for driving direct sales and conversions; social media excels at brand visibility.” (artdigitalmedia.co.uk)
- From a study on engagement:
“Email marketing generates higher click-through and open rates… whereas social media scores higher on brand awareness and content engagement.” (EPRA Journals)
Interpretation: Email’s strength lies in conversion and deep engagement, while social media’s strength is brand and reach.
Implications for Marketers
Based on these case studies and comments:
- Prioritise email when your goal is conversions, sales, or direct response.
- Use social media when your aim is brand awareness, audience building, or engagement, but recognise its lower conversion efficiency.
- Build strategies that use both: social media to attract interest → email to convert interest into action.
- Measure the right metrics: For email, track open / click / conversion; for social, track reach, engagement, and then subsequent conversions (often via email).
- Allocate budget and resources accordingly: The higher ROI of email suggests you should invest sufficiently in list-building, segmentation, personalization, and automation.
