Global Email Usage, Users, and Volume
Email continues to scale at unprecedented levels, with billions of users globally and hundreds of billions of messages sent daily. These foundational statistics show why email remains the backbone of digital marketing and customer communication.
1
4.59 billion people worldwide use email in 2025, representing 56% of the global population
Email has achieved a scale no other direct marketing channel can match. With more than half of humanity reachable via inbox, email gives marketers a distribution advantage that social and paid channels simply cannot replicate at comparable cost.
2
376.4 billion emails are sent and received every day in 2025, growing to 408.2 billion by 2027
Global daily email volume has climbed from 281.1 billion in 2018 to 376.4 billion in 2025, a compound annual growth rate of roughly 4%. For email marketers, this means inbox competition intensifies each year, making sender reputation, subject line relevance, and list hygiene more important than ever.
3
Global email user count is forecast to reach 4.89 billion by 2027, adding roughly 100 million new users per year
Growth is being driven primarily by emerging markets. Asia-Pacific is expanding at 4.2% annually and the Middle East and Africa at 5.1%, fueled by rising smartphone penetration and internet access. For brands with global ambitions, this trajectory makes email list building a compounding long-term asset.
4
The global email marketing market is valued at USD 12.84 billion in 2025 and is projected to reach USD 22.93 billion by 2031 at a CAGR of 10.82%
Sustained double-digit growth reflects how central email has become to marketing infrastructure across industries. Retail and e-commerce hold the largest share at 29.17% of the market, while healthcare is forecast to post the fastest growth through 2031.
5
The United States sends nearly 10 billion emails per day, more than any other country
The US leads all nations in daily email output, with Germany (8.5 billion) and Ireland (8.4 billion) following. This concentration in developed markets underscores why inbox placement rates, authentication standards like DMARC, and sender reputation are especially critical for brands targeting US audiences.
Email Performance and Engagement Benchmarks
Open rates, click rates, and conversion metrics reveal how email campaigns are actually performing across industries. These metrics help you benchmark your performance and understand what constitutes healthy engagement in 2025-2026.
8
43.46% average email open rate recorded across all industries in 2025
MailerLite's benchmark report, drawn from over 3.6 million campaigns, shows open rates rising for consecutive years. However, marketers should interpret this figure with caution: Apple Mail Privacy Protection now affects roughly 46% of email clients, pre-loading emails and inflating open rate data upward.
9
2.09% average email click rate across 3.6 million campaigns in 2025
MailerLite's 2025 benchmark data shows click rates ranged from 0.83% to 4.90% depending on industry, with legal (4.90%), manufacturing (4.22%), and media (4.10%) leading the pack. Because click rate is not distorted by privacy tools, it is now considered the most accurate indicator of real subscriber engagement.
10
6.81% median click-to-open rate (CTOR) across all email campaigns in 2025
MailerLite's dataset shows CTOR ranging from 2.96% to 14.82% by industry. Manufacturing led with a 14.82% CTOR, while politics had the lowest at 2.96%. CTOR is now the go-to metric for measuring content quality, since it measures engagement among people who actually opened the email rather than all recipients.
11
Email open rates rose for the fifth consecutive year in 2025, reaching 30.7% in Omnisend's ecommerce dataset
Omnisend's 2026 Ecommerce Marketing Report, which analyzed close to 24 billion marketing emails, shows open rates climbing from 26.6% in 2024 to 30.7% in 2025. Notably, click-to-conversion jumped 53% year over year, meaning fewer people clicked but those who did were far more likely to buy.
12
Automated emails drove 37% of all email-generated sales in 2024 while accounting for just 2% of email volume
Omnisend's report on 24 billion emails found that one in three people who clicked on an automated message made a purchase, compared to one in 18 for scheduled broadcast campaigns. Abandoned cart, welcome, and browse abandonment flows alone accounted for 87% of all automated orders.
Email Automation and Revenue Impact
Automation is the secret weapon of high-performing email programs. These statistics demonstrate the outsized revenue contribution of automated workflows compared to traditional batch-and-blast campaigns.
16
Automated emails generated 30% of email-attributed revenue from just 2% of total sends in 2025, earning 16x more per send than scheduled campaigns
Omnisend's 2026 eCommerce Marketing Report analyzed over 27 billion emails sent in 2025 and found that behavior-triggered automation dramatically outperforms broadcast campaigns on revenue efficiency. The gap between automated and manual sends continues to widen as shoppers become more selective and intent-driven.
17
Email flows generate nearly 41% of total email revenue from just 5.3% of sends, with revenue per recipient nearly 18x higher than campaigns
Klaviyo's 2026 Email Marketing Benchmarks, drawn from data across over 183,000 customers, confirm that automated flows are the primary revenue engine in email. While campaigns dominate send volume at 94.7% of total sends, flows deliver disproportionate returns, proving that relevance and timing outperform frequency.
18
1 in 3 people who click an automated email make a purchase, compared to just 1 in 18 for scheduled campaign emails
Omnisend's 2025 Ecommerce Marketing Report, which analyzed 24 billion emails sent in 2024, found that automated messages convert at a rate more than 6x higher than one-off campaign sends. For welcome and abandoned cart flows specifically, the purchase rate among clickers rises to 1 in 2.
19
Abandoned cart automated flows generate up to 30x more revenue per recipient than standard one-time email campaigns
Klaviyo's 2024 Benchmark Report, based on over 325 billion emails, found that the average revenue per recipient for abandoned cart flows was $3.65, versus $0.11 for standard campaigns. This 30x gap illustrates the compounding advantage of behavior-triggered automation over batch-and-blast sending.
20
In 2025, behavior-based automated emails generated 25% of total U.S. email revenue from just 1.7% of sends
Omnisend's U.S.-focused ecommerce study published in January 2026 found that American shoppers clicked less often but converted more when they did, rewarding brands that used automation to respond to buying intent in real time. The data covers tens of thousands of U.S.-based SMB ecommerce brands.
Mobile, Personalization, and Segmentation
Mobile dominates email consumption, and personalization remains the top driver of engagement. These statistics show why mobile optimization and audience segmentation are non-negotiable for 2025-2026 success.
22
55% of all email opens now occur on mobile devices in 2025
Mobile has overtaken every other environment for email consumption. If your emails are not built for small screens, you are losing more than half your potential audience before they read a single word.
23
50% of recipients will delete an email immediately if it is not optimized for mobile
Poor mobile rendering does not just reduce engagement, it actively damages it. Subscribers who delete a poorly formatted email are also more likely to unsubscribe or mark future sends as spam.
24
Personalized emails achieve a 29% higher open rate and a 41% higher click-through rate than non-personalized emails
Personalization lifts performance at every stage of the funnel, from the subject line through to the click. These gains compound quickly across a large list, making personalization one of the highest-leverage investments in email marketing.
25
Brands that use personalization increase email ROI to 43:1, compared to just 12:1 for brands that rarely personalize
According to Litmus research, the ROI gap between personalizing brands and non-personalizing brands is nearly 260%. This makes personalization one of the clearest levers for improving the financial return of an email program.
26
Segmented email campaigns generate 30% more opens and 50% more click-throughs than non-segmented campaigns
Segmentation consistently outperforms batch-and-blast sending across every major benchmark. Sending the right message to the right audience is not a best practice, it is the baseline for competitive performance in 2025.
27
Marketers using advanced segmentation report up to a 760% increase in email revenue
First reported by DMA and widely corroborated across industry studies, this figure reflects the compounding effect of relevance: targeted subscribers engage more, convert more, and churn less. The gap between segmented and unsegmented programs is not marginal.
AI Adoption, Privacy, and Deliverability
AI is rapidly transforming email marketing workflows, while privacy regulations and authentication standards are reshaping deliverability requirements. These statistics show the tools and practices that define modern email success.
29
63% of marketers now use AI tools in their email marketing programs
AI adoption in email has crossed the mainstream threshold, with nearly two-thirds of marketers integrating AI tools into their campaigns. This reflects a shift from experimentation to operational dependence, driven by measurable gains in personalization, content creation, and send-time optimization.
30
340% increase in marketers using generative AI to create email images between 2024 and 2025
The Litmus 2025 State of Email report recorded a dramatic surge in AI-generated visual content for email, signaling that AI has moved well beyond subject line writing into full creative production workflows. Teams that adopt AI for design are compressing production timelines and testing more creative variants per campaign.
31
Automated emails generate 320% more revenue while accounting for just 2% of total send volume
The revenue-to-volume ratio for automated email is one of the strongest arguments for investment in trigger-based workflows. Behavior-driven campaigns, including welcome sequences, cart abandonment, and post-purchase flows, consistently outperform broadcast sends because they reach subscribers at the right moment with the right context.
32
48% of email senders say avoiding the spam folder is their biggest deliverability challenge in 2025
Mailgun's 2025 State of Email Deliverability survey of over 1,100 senders found that spam avoidance outranks list hygiene and bounce management as the primary concern. Despite rising authentication adoption, inbox placement remains fragile because ISPs now weigh engagement signals, content quality, and sending behavior alongside authentication status.
33
DMARC adoption rose 11% year-over-year, reaching 53.8% of senders in 2024, up from 42.6% in 2023
Google and Yahoo's February 2024 bulk sender requirements directly accelerated DMARC adoption, with the largest gains seen among high-volume senders where roughly 70% had implemented the protocol by 2024. Despite the progress, a majority of domains still lack enforcement-level policies, leaving them exposed to spoofing and inbox filtering penalties.
Consumer Preferences, Frequency, and Unsubscribe Trends
Consumer behavior is shifting, with email preferences becoming more selective and unsubscribe rates rising. These statistics reveal what subscribers actually want and how email frequency impacts engagement and retention.
37
60% of consumers prefer to be contacted by brands through email over any other channel
Email remains the dominant channel for brand communication, outperforming SMS, social media, and messaging apps. Sinch Mailgun's survey of 2,000+ consumers across the US, UK, France, Germany, and Spain found that 75.4% specifically chose email as their preferred channel for promotional messages, reinforcing email's role as the most trusted inbox for brand outreach.
38
43% of consumers say receiving too many emails is the primary reason they unsubscribe
ZeroBounce's survey of 1,091 respondents across four continents, updated in January 2026, found that email frequency is the single biggest driver of opt-outs. This directly signals that send cadence, not just content quality, is a key lever for reducing list churn and protecting deliverability.
39
The average email unsubscribe rate more than doubled in 2025, rising from 0.08% to 0.22%
MailerLite's benchmark report, based on over 3.6 million campaigns, recorded the median unsubscribe rate jumping to 0.22% in 2025, compared to just 0.08% in 2024. The report attributes much of this increase to Gmail making it easier for users to unsubscribe from promotional emails directly from their inbox, a structural platform shift rather than purely a content problem.
40
Some senders saw unsubscribe volume spike nearly twice their average numbers after Gmail's Subscription Center launched in mid-2025
Salesforce's Marketing Cloud data showed that Gmail's phased rollout of its new Subscription Center feature, starting in June/July 2025, caused dramatic opt-out spikes for many brands. The feature lets users see every sender ranked by frequency and unsubscribe with two clicks, without ever opening a message, fundamentally changing how disengaged subscribers exit lists.
41
69% of consumers cite receiving too many emails as their top reason for unsubscribing, while 56% say content is no longer relevant
Constant Contact consumer research reveals the two primary unsubscribe triggers: volume fatigue and relevance mismatch. These two factors together point to the same solution: better segmentation. Brands that send fewer, more targeted emails consistently see lower opt-out rates than those relying on broad, high-frequency sends.
Email ROI, Market Growth, and Industry Outlook
Email's return on investment continues to outpace all other digital channels, while the market itself is growing rapidly. These statistics demonstrate why email remains the most profitable marketing channel for businesses of all sizes.
43
$36 to $42 returned for every $1 spent on email marketing in 2025
Email marketing's average ROI of $36 to $42 per dollar spent makes it the highest-performing digital channel available, outpacing paid search, social media advertising, and display ads. Retail and ecommerce businesses see the highest industry ROI at $45 per dollar spent.
44
Email marketing market revenue projected to reach $17.9 billion by 2027, up from $12.33 billion in 2024
The global email marketing industry is growing at a compound annual growth rate of 13.3%, driven by rising investment in AI-powered platforms, automation tools, and sophisticated segmentation capabilities. This rapid expansion reflects growing confidence in email as a core revenue channel.
45
75% of marketers plan to maintain or increase their email marketing investment in 2026
Despite a crowded inbox environment, three in four marketers are doubling down on email rather than pulling back. Email also ties with organic social media as the number two most used marketing channel across all business sizes, according to HubSpot's 2026 data.
46
Companies that allocate more than 15% of their marketing budget to email are twice as likely to achieve open rates above 40%
According to Validity's State of Email 2025 report, budget commitment directly correlates with email performance. Brands investing heavily in email are seeing measurably stronger engagement, reinforcing that email success is not just about strategy but also about resource allocation.
47
Global email marketing market valued at $12.84 billion in 2025, projected to reach $22.93 billion by 2031 at a 10.82% CAGR
Mordor Intelligence's January 2026 report puts the email marketing market on a clear multi-year growth path, with SMEs accounting for 57.94% of the market and cloud-based deployment commanding 88.62% of total market share. Asia-Pacific is the fastest-growing region at an 11.18% CAGR.
