There is one marketing channel that has been declared dead more times than any other — and keeps producing the best results in the industry.

Email.

Every few years someone writes the obituary. Social media will replace it. Messaging apps will kill it. Gen Z does not use it. And every year, the numbers come back stronger.

4.6 billion users. $36 to $42 return per $1 spent. 376 billion emails sent every day. A conversion rate that is 8x higher than social media. The most-cited ROI of any digital channel — by a margin that is not close.

This page is the most complete collection of email marketing statistics available today. It covers everything: industry size, ROI, open rates, click rates, B2B benchmarks, B2C benchmarks, automation, personalization, mobile, AI, consumer preferences, and what separates the top 10% from everyone else.

Every stat is sourced. Every source is named.

Quick Stats: The Numbers That Define Email Marketing in 2025 and 2026

The One Fact That Explains Why Email Dominates Every ROI Table

Before the stats: why does email outperform every other digital marketing channel by such a large margin?

One reason. Ownership.

Every other channel you market on is rented. Your social media followers exist on a platform that can change its algorithm, increase its ad prices, restrict your organic reach, or ban your account. Your Google rankings can evaporate from a single algorithm update. Your paid ad audience disappears the moment you stop paying.

Your email list belongs to you. Every subscriber gave you direct permission to contact them. You control the timing, the message, and the frequency. No platform fee. No algorithm. No reach throttling.

That structural advantage — owned audience, direct channel, no intermediary — is why email consistently produces $36 to $42 per dollar spent while social media produces $5 and paid search produces $2.

The numbers throughout this page reflect that advantage. Keep it in mind as you read them.

Email Marketing Industry Size and Growth

Quick Answer: The global email marketing industry generated $8.17 to $12.33 billion in revenue in 2024, depending on the definition used. It is projected to reach $17.9 billion by 2027 and $27.88 billion by 2032. The industry is growing at 13.3% to 16.6% annually — faster than most other marketing channels.

1. The global email marketing industry was valued at $8.17 billion in 2024 and is projected to reach $27.88 billion by 2032, growing at a CAGR of 16.58% during the forecast period 2026 to 2032. — Verified Market Research, Email Marketing Market Report 2025-2033
2. A separate estimate from Statista places the global email marketing market revenue at $12.33 billion in 2024. The difference between the two figures reflects how each study defines the market — software only versus software plus services plus agency spending. — Statista via DemandSage
3. Email marketing revenue is projected to reach $17.9 billion by 2027, growing at a CAGR of 13.3% between 2020 and 2027. The industry grew from $7.5 billion in 2020 — a 138% increase in seven years. — Statista via DemandSage
4. Email software makes up 68.1% of total email marketing market revenue, growing at a projected CAGR of 11.8% through 2032. Email services and agencies make up the remaining 31.9%. — Verified Market Research, Email Marketing Market Report 2025-2033
5. The conservative consensus for the email marketing market runs from $7 billion to $10 billion in 2025 and $18 billion to $25 billion by 2030 — implying a 14% to 18% CAGR that makes email marketing one of the fastest-growing segments of the marketing technology industry. — Verified.email, B2B Benchmarks Forecast 2026-2030
6. 376 billion emails are sent every single day in 2025 — up from 361 billion in 2024 and 333 billion in 2022. Daily email volume is growing by approximately 14 billion emails per year. — Statista via Omnisend
7. Global email users reached 4.6 billion in 2025 and are projected to hit 4.73 billion by 2026 and 4.97 billion by 2028 — surpassing 60% of the global population. No social platform comes close to this reach. — Statista via Forbes
8. 79% of marketers include email within their top three marketing channels. It is the only channel that appears in every version of every “most effective channels” survey — regardless of industry, company size, or geography. — Porch Group Media, Email Marketing Benchmarks 2025

What the data shows: Email is not just holding its ground. It is growing faster than most of the channels that were supposed to replace it. The same year TikTok crossed 1 billion users, email passed 4.6 billion. Scale is not email’s problem. Execution is.

Email Marketing ROI Statistics

Quick Answer: Email marketing returns $36 to $42 for every $1 spent — the highest documented ROI of any digital marketing channel. Brands that prioritize personalization push that to $43 per dollar. Frequent A/B testers see ROI of $42 per dollar versus $23 for those who never test. And 52% of email marketing professionals have doubled their ROI from email campaigns.

9. Email marketing delivers an average ROI of $36 for every $1 spent, giving it the highest documented return of any digital marketing channel. — Litmus via Forbes
10. US merchants with optimized email programs achieve an average of $68 to $72 in revenue for every $1 spent on email. The global average is $36 to $42. The difference reflects what proper automation, segmentation, and list hygiene actually unlock. — Omnisend via Mailotrix Research
11. Brands that prioritize email personalization push average ROI from 36:1 to approximately 43:1. Brands that rarely personalize average just 12:1. The personalization ROI gap is 3.5x. — InsightMark Research, B2B Email Marketing Statistics 2026
12. Frequent A/B testers see approximately 86% higher email ROI — averaging 42:1 — compared to 23:1 for those who never test their campaigns. This is one of the largest single-practice ROI gaps in all of email marketing. — InsightMark Research, B2B Email Marketing Statistics 2026
13. 52% of email marketing professionals report doubling their ROI through email campaigns. — Sopro, Email Marketing Statistics 2025
14. B2B email marketing specifically delivers an ROI of $38 for every $1 spent — slightly above the global average — driven by longer customer lifetime values and higher average deal sizes. — Competitors App, Email Marketing Stats 2025
15. Email is 40x more effective than Facebook and Twitter combined for customer acquisition. — Campaign Monitor via Porch Group Media
16. Email traffic converts to purchases at a 4.24% rate. Search traffic converts at 2.49%. Social media traffic converts at just 0.59%. Email is 8.5x more likely than social media to produce a purchase from the same visitor. — GrowthNavigate, Email Marketing Statistics
17. 59% of marketers consider email marketing more than twice as effective as paid advertising for generating leads. — Powered by Search, B2B Email Marketing Stats 2025
18. The industries reporting the highest email marketing ROI in 2024 were marketing, PR, and advertising — followed by retail, ecommerce, and consumer goods. These sectors benefit from short purchase cycles and audiences already conditioned to act on promotional email content. — GrowthNavigate, Email Marketing Statistics
19. For every $1 spent on email marketing, the return across retail and ecommerce specifically reaches $45 on average — above the all-industry average — because transaction-driven emails like cart abandonment and welcome flows generate disproportionately high per-send revenue. — Stripo, Email Marketing ROI Statistics 2024
20. 30% of marketers globally rate email as their highest-ROI channel. Another 43% rate it as medium ROI. No other digital channel shows this level of consistent cross-industry performance recognition. — Omnisend, Email Marketing Statistics 2026

What the data shows: The $36 ROI figure is the average. Not the ceiling. The brands systematically using personalization, A/B testing, automation, and segmentation are producing 43:1, 68:1, even higher. The average is being pulled down by the majority of programs that send generic broadcast emails to unsegmented lists with no automation in place. Fix those three things and the floor becomes $43 per dollar.

The Email Marketing ROI Calculator: What These Numbers Mean for Your Business

This is the math most email marketing statistics pages never run.

A business spending $500 per month on its email marketing platform sends campaigns to 10,000 subscribers.

At the all-industry average ROI of 36:1, that $500 generates $18,000 in email-attributed revenue per month — $216,000 annually.

A brand that adds proper personalization pushes that to 43:1 — $21,500 per month, $258,000 annually. That is $42,000 more per year from the same list and the same platform budget. Just better targeting.

A brand that adds A/B testing pushes ROI toward 42:1 — $21,000 per month from the same $500 spend.

A brand that builds proper automation on top of that — welcome flows, cart recovery, post-purchase — moves 30% to 41% of email revenue into automated sends that produce 16x to 18x more revenue per send than campaigns. On a 10,000-subscriber list generating $18,000 per month from campaigns, a well-built automation stack can add $5,000 to $7,400 in flow revenue on top of that baseline.

The brands generating $68 to $72 per dollar spent are not using a fundamentally different strategy. They are using the same strategy — fully executed. The math rewards completion.

Email Marketing Benchmarks: Open Rate, Click Rate, and Conversion

Quick Answer: The average email open rate in 2025 was 30.7% across all industries (Omnisend) or 42.35% when measured differently due to Apple MPP inflation. The true pre-MPP industry average was 21.33%. Average CTR runs 1.40% to 2.00%. Average conversion rate is 2.4% to 2.5% for B2B and 2.8% for B2C.

21. Open rates rose for the fifth consecutive year in 2025, increasing from 26.6% in 2024 to 30.7% globally — even as click rates declined. — Omnisend, Email Marketing Statistics 2026
22. The average email open rate across all industries before Apple’s Mail Privacy Protection (which inflated the metric from September 2021 onward) was 21.33%. Post-MPP averages now run 30.7% to 43.46% depending on the dataset. The pre-MPP baseline is the most accurate benchmark for year-over-year trend comparison. — DemandSage, Email Marketing Statistics 2026
23. The average email click-through rate across all industries is 1.40% in Mailchimp’s benchmark data and 2.00% in B2B-focused datasets. Click-to-open rate (CTOR) averages 5.63% to 6.81% depending on the platform and audience. — DemandSage / Powered by Search
24. Click-to-conversion rate jumped 53% year over year in 2025 — rising from 5.9% to 9.0% across Omnisend’s ecommerce dataset. Fewer people are clicking, but those who do are far more likely to buy. — Omnisend, Email Marketing Statistics 2026
25. The average email conversion rate is 2.4% for B2B and 2.8% for B2C. B2B tech specifically averages 2.5% conversion rate from email campaigns. — FirstPageSage / Competitors App
26. The average email unsubscribe rate across all industries in 2025 was 0.22% — more than double the 2024 figure of 0.08%, largely because Gmail made one-click unsubscribe more visible to recipients. — MailerLite, Email Marketing Benchmarks 2025
27. The average time spent reading an email is less than 9 seconds. This means your subject line, preheader, headline, and primary CTA need to carry the entire message — because most subscribers will never reach the bottom of your email. — Sopro, Email Marketing Statistics 2025
28. A good email open rate falls between 17% and 28% using pre-MPP measurement standards. When using post-MPP data, acceptable rates shift upward significantly — making historical comparisons unreliable without accounting for the methodology change. — DemandSage, Email Marketing Statistics 2026
29. Government emails achieve the highest average open rate at 28.77% (pre-MPP measurement). Faith-based organizations have the highest click rate at 2.46%. Software and technology consistently show the highest bounce rates at 1.04%. — Mailchimp via DemandSage
30. Open rates have almost doubled over the past decade — rising from 18.7% in 2016 to 35.9% in 2024. Some of that increase is real engagement growth. Much of it is Apple MPP inflation. The click-to-open rate declining from 10.3% in 2016 to 6.4% in 2024 is the more honest engagement trend. — Sopro, Email Marketing Statistics 2025

B2B Email Marketing Statistics

Quick Answer: 4 in 5 B2B marketers rely on email as their primary marketing channel. 73% of B2B buyers prefer email as their primary communication channel with sellers.

31. Four in five B2B marketers rely on email marketing as their primary content distribution and lead generation channel. — Sopro, Email Marketing Statistics 2025
32. 73% of B2B buyers prefer email as their primary communication channel with vendors and sellers — more than phone, social media, or in-person meetings. — HubSpot via MyEmailVerifier
33. Almost three-quarters of B2B buyers prefer to be contacted through email, making it the most preferred channel across the entire buying journey from awareness to close. — Sopro, Email Marketing Statistics 2025
34. The median B2B open rate in 2025 sits at 36.7% to 42.35% — up from 34.2% in 2024. Top-quartile B2B email programs achieve open rates above 50% and CTRs above 10% through rigorous segmentation, AI-powered personalization, and deliverability optimization. — Verified.email, B2B Benchmarks Forecast 2026-2030
35. Average B2B CTR sits between 2.0% and 4.0%. B2B CTOR averages 5.63% to 6.81%, with strong programs consistently exceeding 7% to 10%. — Verified.email, B2B Benchmarks Forecast 2026-2030
36. Overall B2B email delivery rate in 2025 is approximately 98.16% — meaning the vast majority of emails sent to valid, maintained B2B lists successfully reach the receiving server. Inbox placement — whether the email lands in the primary inbox versus spam — is the more important downstream metric. — InsightMark Research, B2B Email Marketing Statistics 2026
37. The top two email types that B2B marketers send most frequently are email newsletters (81%) and welcome emails (79%). These two formats form the backbone of virtually every B2B email program. — Powered by Search, B2B Email Marketing Stats 2025
38. B2B buyers prefer email content under 200 words. Whitepapers, case studies, and reports are the most commonly downloaded content formats from B2B email campaigns. — HubSpot via Competitors App
39. 90% of B2B marketers prioritize email engagement as their primary performance metric. 63% consider increasing email engagement their most important and most challenging ongoing task. — Ascend2 via Stripo
40. 44% of US B2B marketers specifically cited the overarching efficiency of email for B2B promotion and sales as its primary advantage over other channels. — Stripo, B2B Email Marketing Statistics 2025
41. Cold email campaigns achieve an average open rate of 36% and a 5.1% response rate when properly personalized. Engagement decay is real: cold outreach reply rates dropped from 6.8% in 2023 to 5.8% in 2025, reflecting rising inbox fatigue across B2B audiences. — Woodpecker via MyEmailVerifier / Verified.email

What the data shows: The gap between the median and top-quartile B2B email program is not technical. It is executional. A 42% open rate versus a 50%+ open rate. A 3% CTR versus a 10%+ CTR. The programs consistently hitting top-quartile metrics are doing three things better than everyone else: segmenting by buyer stage, personalizing by role and behavior, and maintaining list hygiene that keeps deliverability strong.

Personalization and Segmentation Statistics

59. Only one-third of email marketers use personalization consistently — despite the estimated 10% to 15% direct revenue increase it produces and the documented 6x transaction rate improvement. The gap between what personalization delivers and how many marketers use it is the largest single opportunity in email marketing. — Sopro, Email Marketing Statistics 2025
60. At least 86% of consumers say they are happy to share their email contact information if it means they will receive personalized offers in return. Subscribers actively want relevant emails. The problem is that most brands do not deliver on that expectation. — Powered by Search, B2B Email Marketing Stats 2025

The Personalization Gap: What the Data Says Is Possible vs. What Most Brands Actually Do

This is the most important analysis gap in email marketing statistics.

Here is what the research says is possible with personalization:

• 6x higher transaction rates
• 760% more revenue from segmented campaigns
• 82% higher open rates
• 15% higher customer lifetime value
• 43:1 ROI versus 12:1 for non-personalizers

Here is what actually happens in practice:

• Only one-third of email marketers use personalization consistently
• Only 41% to 42% of marketers have a documented content strategy
• 63% of people say they never respond to non-personalized emails
• Most programs still send the same email to their entire list for most campaigns

The gap between what personalization delivers and how many programs actually use it is the single biggest opportunity in email marketing today. It is not a technology problem — every major email platform from MailerLite to Klaviyo supports advanced segmentation. It is an execution problem. The brands willing to do the work are capturing dramatically more revenue from the same list size.

Email Automation Statistics

What Top-Quartile Email Marketing Programs Do That the Median Program Does Not

The data across every major email benchmark study points to the same gap. The top 25% of email programs are not using a different strategy. They are executing the same fundamentals — more completely, more consistently, and with more data behind every decision.

They have built automation before they invest in campaign volume. Automated emails produce 15.9x to 18x more revenue per send than campaign emails. Top programs build their five core flows — welcome, abandoned cart, browse abandonment, post-purchase, win-back — before optimizing campaign frequency. Every campaign budget dollar spent before these flows are live is working at 1/18th the efficiency it could be.

They segment before they personalize. Segmentation is the infrastructure. Personalization is the execution on top of that infrastructure. Marketers who try to personalize without segmenting first end up with personalized emails going to the wrong segments — which produces worse results than generic emails to the right segments. The 760% revenue uplift from segmented campaigns in HubSpot’s data is driven by relevance, not just personalization tokens.

They A/B test as a system — not a one-off. Frequent A/B testers produce 86% higher ROI (42:1) versus those who never test (23:1). The difference is not any single winning test. It is the compounding effect of continuous marginal improvement across subject lines, CTAs, send times, and content formats. Each 1% improvement compounds.

They measure revenue per recipient — not open rate. The top-quartile programs that Klaviyo and Omnisend benchmark against are not optimizing for open rates inflated by Apple MPP. They are optimizing for RPR (revenue per recipient) — the only metric that survives Apple’s privacy inflation because it is anchored to actual transactions, not pixel fires.

They treat list hygiene as a growth lever. The brands achieving $68 to $72 per dollar on email are not the ones with the biggest lists. They are the ones with the cleanest, most engaged, best-segmented lists. Removing disengaged subscribers improves deliverability, which improves inbox placement, which improves open rates, which improves conversion — for every remaining subscriber on the list.

6 Email Marketing Myths the Data Completely Disproves

Myth 1: Email is dying.

Email users are growing by approximately 500 million per five-year period. 376 billion emails are sent every day and growing. The email marketing industry is expanding at 13% to 16% annually. Gen Z and Millennials — the audiences most likely to “abandon” email — actually prefer email contact from brands at 57% and 79% respectively. Email is not dying. Email marketing that is generic, irrelevant, and over-sent is dying.

Myth 2: Social media is a better channel for reaching younger audiences.

79% of Millennials prefer email contact from brands. 57% of Gen Z does too. Email converts at 4.24%. Social media converts at 0.59%. For purchase-driving communications specifically, email outperforms social media for every demographic the data covers. Social media is a discovery and engagement channel. Email is a conversion and retention channel. They are not competing — but if you had to choose one to drive revenue, the data makes the answer clear.

Myth 3: More emails mean more revenue.

96% of recipients have unsubscribed because a brand sent too frequently. The average person receives 121 emails per day. The brands generating the highest email ROI are not the ones sending the most emails. They are the ones sending the most relevant emails to the most targeted segments at the right moment. Volume is the lazy lever. Relevance is the high-ROI lever.

Myth 4: Personalization just means adding a first name.

First name personalization lifts open rates by 26%. Behavioral personalization — referencing purchase history, browsing behavior, and engagement signals — lifts transaction rates by 6x and can produce ROI of 43:1 versus 12:1. The brands still treating “personalization” as a merge tag are capturing about one-seventh of the available revenue uplift.

Myth 5: Automation is complicated and expensive.

76% of marketers use email automation. Every major email platform — including MailerLite, GetResponse, and Klaviyo — has automation built in at pricing accessible to small businesses. The complexity barrier is perception, not reality. A basic welcome series and cart abandonment flow can be built in a day. Those two flows alone typically generate the majority of automation revenue for most ecommerce brands.

Myth 6: Email deliverability is a technical problem you outsource.

Email deliverability is a content, list quality, and sender reputation problem — all of which marketing owns, not IT. The brands with 98%+ delivery rates and strong inbox placement are not the ones with the most sophisticated technical setups. They are the ones cleaning their lists quarterly, suppressing hard bounces immediately, authenticating their domains properly, and keeping spam complaint rates below 0.1%. Deliverability is a marketing discipline.

Email Marketing Statistics: Key Takeaways

Here is what 110+ data points across every dimension of email marketing come down to:

Email is the highest-ROI channel in digital marketing — and it is not close. $36 to $42 per dollar versus $5 for social and $2 for PPC. The gap exists because email is the only channel you fully own, where you control timing and targeting without paying a platform intermediary. The brands investing proportionally to that ROI advantage are compounding faster than those who are not.

Automation is where the ROI lives. 2% of email sends. 30% to 41% of email revenue. 15.9x to 18x more revenue per send than campaigns. If your email program is primarily campaigns without automated flows, you are earning less than 6% of the revenue potential of the same list.

Personalization is the largest untapped opportunity in email. 6x higher transaction rates. 760% more revenue from segmented sends. 43:1 ROI for personalizers versus 12:1 for non-personalizers. And only one-third of email marketers use it consistently. This is the rare situation where the highest-ROI improvement is also the least saturated.

Mobile is not the future of email. It is the present. Over 50% of opens happen on mobile. 50% of recipients delete emails that are not optimized for their phone. 88% of smartphone users check email on their devices. Any email marketing strategy that does not start with mobile-first design is broken for the majority of the audience it is trying to reach.

List quality beats list size every time. The brands generating $68 to $72 per dollar are not the ones with the biggest lists. They are the ones with the most engaged, best-segmented, cleanest lists. More subscribers is a vanity metric. More engaged, more targeted, better-maintained subscribers is a revenue metric.

AI is widening the gap between the top programs and everyone else. 60% of marketers use AI daily for marketing tasks. AI personalization produces 13.44% higher CTR and 41% more revenue. AI subject lines outperform human-written ones by 26%. The programs that have integrated AI into their personalization, segmentation, and send-time optimization are already operating at a performance level that manual execution cannot match at scale.
