Email Marketing Statistics: Key Data Points for 2025 and 2026

Email marketing statistics help businesses benchmark their performance, justify budget decisions, and identify where strategy needs adjustment. This article compiles data across usage, ROI, open rates, conversion, automation, and mobile drawing from multiple research sources, including platform providers and independent studies.

Email Usage Statistics

Email is not shrinking. If anything, it keeps growing quietly, without the fanfare that surrounds newer channels.

How Many People Use Email Worldwide

According to data from Statista, there are currently 4.48 billion email users worldwide, with that number projected to reach 4.73 billion by 2026. Every second, more than 3.13 million emails are sent globally. Daily, that adds up to roughly 361.6 billion emails a figure expected to climb to 408.2 billion by 2027.

Gmail leads as the most widely used email provider, with 1.8 billion active accounts. The average person holds at least 1.86 email accounts.

Top countries by daily email volume:

Rank	Country
1	United States
2	Germany
3	India
4	Belgium
5	France
6	Japan
7	Ireland
8	United Kingdom
9	Netherlands
10	Australia

How Often People Check Their Email

88% of people check their email every day. A notable 39% check it three to five times daily. For 80% of users, the primary reason is work-related messages  though 40% also regularly scan for brand discounts and promotions.

58% of consumers check email before they check social media or the news in the morning. 20.41% of emails are opened within the first hour of delivery.People also check email in contexts that might surprise you. 69% do it while watching TV. 57% check in bed. 

79% check on vacation. Email fits into gaps it doesn't demand dedicated attention the way other channels do. As reported by Forbes Advisor, consumers spend an average of 10 seconds reading brand emails with 61% engaging for eight seconds or more, while 15% look at an email for under two seconds before moving on.

Email Usage by Age Group and Demographics

Age Group	Email Usage Rate
15–24	90%
25–44	93.6%
45–64	90%
65+	84.1%

91% of women in the US use email, compared to 89% of men. People aged 35 and older spend an average of five hours per day using email across personal and professional activity. Generationally, attitudes toward email differ. 

74% of Baby Boomers consider email the most personal channel for brand communication. That figure drops to 72% for Gen X, 64% for Millennials, and 60% for Gen Z still a majority across every group, but a clear downward trend worth monitoring.

Year-Over-Year Trends in Email Usage

Global email volume has grown consistently year on year. The email marketing industry itself grew from a market value of $7.5 billion in 2020 toward a projected $17.9 billion by 2027. In practice, most marketing teams report that email remains their most measurable and cost-controllable channel even as newer platforms compete for attention budget.

Email Marketing Adoption Statistics

Business and Marketer Adoption Rates

81% of companies use email as part of their marketing strategy. Among small businesses specifically, 64% use email marketing partly because the barrier to entry is low, and partly because it scales without proportional cost increases.

Half of all marketers say email is their most impactful channel. Nearly 90% plan to maintain or increase their email marketing spend. 79% include email in their top three marketing channels overall.

One-third of marketers actively use email marketing as a primary campaign vehicle. 89% use it as their main lead generation channel. For teams exploring startup tools for digital marketing, email platforms are consistently among the first investments made largely because the cost-to-reach ratio is difficult to match early on.

Email Send Frequency Benchmarks

Most businesses send emails two to four times per month enough to maintain visibility without exhausting the list. 32% of marketers contact their audience two to three times monthly, 19% send four to six times, and 17% send once a month.

Tuesday and Thursday tend to produce the strongest results. 18% of emails are sent on Thursdays, 17% on Tuesdays, 16% on Wednesdays. 11 AM is widely cited as the optimal send time, with 12 PM showing the highest click-through rates.

That said 50% of marketers say there is no universally correct send time. Audience behavior varies too much for blanket rules to hold.

B2B vs. B2C Email Marketing Statistics

B2B and B2C audiences use email differently. The channel is the same. The expectations, buying cycles, and content formats are not.

B2B Email Marketing Benchmarks

81% of B2B marketers use email marketing to reach their audience. 73% say it is their most effective method of contacting prospects ahead of phone calls, events, and paid advertising.

77% of B2B buyers say email is their preferred form of contact from vendors. This makes sense in practice: email creates a record, allows review before responding, and doesn't demand immediate attention the way a phone call does.

B2C Email Marketing Benchmarks

On the consumer side, email drives direct purchasing behavior more consistently than most other channels. 59% of people say marketing emails influence their purchasing decisions. 50% report buying from a marketing email at least once per month. 23.8% do so several times per month.

Anniversary and birthday emails triggered around personal milestones achieve open rates three times higher than standard emails sent to the same audience (56% vs. 17%). Revenue per email from anniversary sends is nearly seven times that of bulk mailings.

People are three times more likely to make a purchase from an email campaign than from a social media promotion. Businesses that also advertise across multiple digital channels typically find email delivers the most consistent cost-per-acquisition when tracked over a full campaign cycle.

Email List Building Statistics

A large open rate means nothing on a list of 200 people. List size and list health are where email performance actually starts.

Average Email List Sizes by Business Type

Nonprofits average 4,191 contacts per list 547 for small organizations and 6,602 for large ones. General small business benchmarks vary considerably by industry and time in operation, but teams commonly report that building a quality list of even a few thousand engaged contacts takes one to two years of consistent effort.

How Businesses Grow Their Email Lists

Only 17% of organizations use email subscribe popups on their website. 13% use gated content resources behind an opt-in form to grow their list. Both figures suggest most businesses are underleveraging the list-building mechanisms that are readily available to them.

Average email list growth came in at 4% in 2024, down from 6% in 2023. Slow list growth combined with normal subscriber churn means many businesses are running to stand still.

Email List Decay and Churn

In 2024, 9% of subscribers unsubscribed and 7% became non-deliverable due to bouncing. That's roughly 16% annual list loss before any growth effort.Only 35% of marketers regularly delete unengaged subscribers. 

In practice, retaining inactive contacts inflates list size numbers while quietly dragging down open rates and deliverability scores. Most email platforms count inactive addresses the same as active ones for billing purposes which creates a perverse incentive to keep lists large rather than clean.

Email Marketing ROI Statistics

ROI is the statistic most often used to justify email marketing budgets. It is also the one with the widest variation across sources.

Average Return on Investment

Depending on the source, the average email marketing ROI lands somewhere between $36 and $42 for every $1 spent. Constant Contact puts it at $38. Omnisend reports $40. The most commonly cited figure is $42. The median ROI across studies is 122% approximately four times higher than any other digital marketing channel.

18% of companies report achieving ROI above $70 per $1 invested. A/B testing alone is associated with up to a 37% improvement in email marketing ROI.What's worth noting here: most of these figures come from email platform providers or studies commissioned by them. That doesn't make them wrong but it's worth treating the upper ranges with some skepticism.

Email Marketing Budget and Spend

87% of marketers plan to invest more in their email marketing budget. For teams working with limited resources, applying practical budget strategies to marketing spend can help prioritize email tools and list-building costs without overextending early on. 

The global email marketing market was valued at $7.5 billion in 2020 and is projected to reach $17.9 billion by 2027. Worldwide email marketing revenue reached an estimated $12.33 billion in 2024.

Email Revenue Contribution

Email drives approximately 25% of overall revenues for companies that actively invest in it. In the nonprofit sector, email messaging accounted for 11% of all online revenue in 2024 — down from 14% in 2023.

Email ROI by Industry

The industries reporting the highest email marketing ROI in 2024 were marketing, PR, and advertising, followed by retail, e-commerce, and consumer goods. These sectors benefit from short purchase cycles and audiences already conditioned to act on promotional content.

Email vs. Other Channels

4.24% of email traffic leads to purchases. Search traffic converts at 2.49%. Social media traffic converts at 0.59%. Email is not just cheaper than paid channels it converts at a meaningfully higher rate.

Email Open Rate Statistics

What is an open rate? It measures the percentage of delivered emails that are opened. Since Apple's Mail Privacy Protection update, open rate tracking has become less reliable for Apple Mail users some industry benchmarks may be slightly inflated as a result.

Average Email Open Rates by Industry

The overall average open rate for email marketing campaigns is 36.5%. But that average masks significant variation.

Industry	Open Rate
Faith-Based Organizations	45.5%
Child Care Services	44.8%
Family and Social Services	42.7%
Nonprofit Membership Organizations	42.3%
Nonprofit Services	41.8%
Recreation, Sports & Entertainment	41.8%
Independent Artists & Performers	41.4%
Education	40.2%
Home & Building Services	39.3%
Dining and Food Services	37.6%

Industries with highly engaged, mission-aligned audiences consistently outperform transactional sectors. That pattern holds across multiple data sources and years.

Triggered and Lifecycle Email Open Rates

Welcome emails achieve an average open rate of 80% by far the highest of any email type. Abandoned cart emails reach 50.5%, which is 15% higher than the average campaign open rate. 

Anniversary and birthday emails hit 56% triple the rate of standard campaigns to the same list.

The implication is straightforward: emails sent in response to a specific action or moment outperform broadcast emails by a wide margin.

What Affects Open Rates

• Personalized subject lines increase open rates by 26%

• Subject lines with 6–10 words achieve the highest open rates

• Urgent subject lines increase open rates by 22%

• Emails with the recipient's name in the subject line: 18.3% open rate vs. 15.7% without

• Emails with questions in subject lines: +50% open rate

• The word "Video" in a subject line: +19% open rate

Email Click-Through Rate Statistics

What is click-through rate (CTR)? CTR measures the percentage of delivered emails where at least one link was clicked. It differs from click-to-open rate (CTOR), which measures clicks only among people who opened the email. The two are often conflated worth distinguishing when benchmarking.

Average Click-Through Rates by Industry

The overall average CTR for email campaigns is 1.4%.

Industry	Click-Through Rate
Technology Services	2.6%
Transportation Services	2.6%
Faith-Based Organizations	2.5%
Family and Social Services	2.1%
Nonprofit Membership Organizations	1.9%
Nonprofit Services	1.9%
Admin & Business Support Services	1.8%
Child Care Services	1.7%
Education	1.7%
Legal Services	1.6%

What Affects Click-Through Rates

Including video in emails can boost click-through rates by 65% and the word "video" in a subject line alone increases CTR measurably. Personalized calls to action convert 202% better than default, generic CTAs. 

Countdown timers in emails are associated with a 30% increase in registrations. Mobile optimization is directly tied to click behavior: launching a mobile-responsive design increases unique mobile clicks by 15%.

Email Conversion Rate Statistics

What is an email conversion rate? A conversion happens when a recipient completes the desired action a purchase, a signup, a donation. It is distinct from opening an email or clicking a link. Conversion rate is the metric most directly connected to revenue.

Average Email Conversion Rates

The average email conversion rate is 3%. For context: email traffic converts at 4.24%, outperforming search traffic (2.49%) and social media traffic (0.59%) by a significant margin. Email is not just a reach channel it is a conversion channel.

What Drives Higher Email Conversion Rates

Personalization has the largest documented impact on conversion. Personalized emails generate six times higher transaction rates than non-personalized ones. Segmented email lists are associated with a 760% increase in revenue the single highest-impact tactical lever in email marketing.

Automated email flows abandoned cart sequences, post-purchase follow-ups, re-engagement series generate up to 30 times more revenue per recipient than standard broadcast campaigns. The difference is timing and relevance. A/B testing consistently improves conversion outcomes, with documented ROI improvements of up to 37%.

Purchase Behavior from Marketing Emails

• 50% of subscribers buy from a marketing email at least once a month

• 23.8% do so several times per month

• 3% purchase via email more than once per week

• Consumers who purchase through email spend 138% more than those who do not receive email offers

• 59% of people say marketing emails influence their purchasing decisions

Email Segmentation Statistics

Segmentation is consistently rated the most effective email marketing strategy ahead of personalization and automation. Yet adoption is far from universal.

Segmentation Adoption Among Marketers

78% of marketers use subscriber segmentation, making it the top-reported email strategy. 72% use message personalization, and 71% use email automation campaigns. 66% personalize based on demographic data such as age.

Segmentation Impact on Performance

Marketers who segment their email lists report revenue increases of 760% compared to non-segmented sends. That is a figure worth pausing on not because it should be taken as a guaranteed outcome, but because it reflects how dramatically relevance affects email performance. 

Sending the right message to a smaller, correctly identified group routinely outperforms sending a generic message to an entire list.In practice, most teams find that even basic segmentation by purchase history, geographic location, or engagement level produces measurable improvement within the first few campaign cycles.

Email Personalization Statistics

Personalization operates at the individual level tailoring content, subject lines, or offers to a specific recipient's data or behavior. It overlaps with segmentation but is not the same thing.

Impact on Open Rates and Conversions

• Personalized subject lines: +26% open rate

• Recipient's first name in subject line: +9.1% open rate lift

• Personalized emails: 6x higher transaction rates

• 80% of consumers are more likely to purchase from a personalized email

Consumer Attitudes Toward Personalization

83% of customers say they are willing to share personal data in exchange for a more personalized experience. 79% say they will only engage with an offer email if it reflects their previous interactions with the brand. 

74% say they actively dislike being shown irrelevant content.The expectation of relevance is no longer a differentiator it is a baseline.

How Marketers Implement Personalization

77% of marketers say they use email to send personalized content. 72% cite message personalization as a core strategy. Demographic-based personalization particularly by age is used by 66% of marketers. AI is increasingly used to scale personalization beyond what manual segmentation can achieve, covered further in the automation section below.

Mobile Email Statistics

Mobile is not an emerging trend in email. It is the current reality. Designing for desktop first is designing for a minority of your audience.

Mobile Email Open and Usage Rates

Device	Share of Email Opens
Mobile	41%
Desktop	39%
Webmail	40.6%

85% of users access their inbox on a mobile device. 75% of Gmail users read their emails on a smartphone or tablet. About three in five consumers check email on the go.

Generational Mobile Email Behavior

59% of Millennials primarily use their mobile phone to check email. 67% of Gen Z scan their inbox on mobile. Even among business professionals, 35% view emails on mobile devices. The pattern holds across age groups mobile is dominant.

Consequences of Poor Mobile Optimization

42.3% of users delete emails that are not optimized for mobile. Nearly one in five email campaigns is still not properly optimized for mobile devices. That gap has real consequences: poorly rendered emails lead to immediate deletion and, in some cases, unsubscribes.

Launching a mobile-responsive email design increases unique mobile clicks by 15%. A 65% higher chance of website visits follows reading a well-formatted mobile email. The cost of ignoring mobile optimization is measurable.

Email Automation and AI Statistics

Email Automation Adoption and Performance

58% of businesses include automation as part of their email strategy. The performance difference between automated and broadcast emails is substantial. Automated flows abandoned cart, post-purchase, re-engagement generate up to 30 times more revenue per recipient than standard campaigns.

Abandoned cart emails specifically achieve a 50.5% open rate. That is 15% above the average campaign open rate, and it makes sense: the recipient has already demonstrated intent. The email arrives at a moment of relevance.

AI Use in Email Marketing

AI adoption in email marketing is growing, though reported figures vary depending on who is asking and how the question is framed. 

Among marketers using AI:

• 47–81% use AI in email campaign creation (range reflects different survey populations)

• Top use cases: content personalization (50%), subject line optimization (47%), retargeting (47%)

• 85% of those using AI for email report that it improved content quality

• 47% describe AI's overall impact on email marketing as extremely positive

Where AI Adoption Is Heading

45% of email marketers expect AI to play a central role in all aspects of email marketing going forward, not just content creation, but segmentation, send-time optimization, and campaign analytics. 

Teams commonly report that AI tools reduce the time spent on subject line testing and content drafting, though the quality still depends heavily on the input and prompting strategy. The efficiency gains are real; the outcomes are not automatic.

Email Subject Line Statistics

The subject line determines whether an email gets opened or ignored. It is the headline, the first impression, and the primary filter — all in under 60 characters.

Subject Line Length and Format Benchmarks

The average email subject line is 43.85 characters. Subject lines with 6–10 words achieve the highest open rates. Questions in subject lines are associated with a 50% higher open rate. Numbers in subject lines produce a 17% lift.

Subject Line Elements and Their Impact on Open Rates

Element	Open Rate Impact
Personalized name	+9.1% to +18.3%
Urgency language	+22%
Word "Free"	+10%
Word "Video"	+19%
Emoji present	~39% avg open rate
Question format	+50%
Number included	+17%

The range on name personalization reflects different studies measuring the same variable the lift is consistent, but the magnitude varies by list and industry.

Subject Lines and Spam Triggers

69% of recipients report an email as spam based on the subject line alone before opening it. Certain language patterns, excessive punctuation, and misleading urgency phrases are common triggers. Subject line decisions affect not just open rates but deliverability reputation over time.

Email Bounce Rate, Deliverability, and List Health Statistics

Definitions: A hard bounce occurs when an email cannot be delivered because the address is invalid or no longer exists. A soft bounce is a temporary failure a full inbox or a server issue. Deliverability refers to whether emails reach the inbox at all, as opposed to the spam folder or being blocked entirely.

Deliverability and Inbox Placement

2024 saw increased industry focus on email authentication protocols SPF, DKIM, and DMARC as a response to rising phishing activity and tightening inbox provider standards. Google and Yahoo both introduced stricter sender requirements in 2024, making authentication no longer optional for bulk senders.

In practice, organizations that neglect authentication find their emails increasingly filtered or blocked regardless of content quality.

Phishing and Email Security Statistics

• 298,878 phishing attack victims were reported in the US in 2023

• Associated financial losses totaled approximately $18.7 million

• For every 12.5 million spam emails sent, spammers receive one reply yet the economics of volume make it viable

Security awareness is increasingly relevant to email marketers because phishing erodes consumer trust in email generally. A skeptical inbox is a harder inbox to convert.

Conclusion

Email marketing statistics consistently show strong ROI, high adoption, and measurable influence on purchasing behavior. Performance varies significantly by industry, list quality, and how well campaigns are personalized and segmented. The data supports email as a durable channel not a declining one.

Frequently Asked Questions

What is a good open rate for email marketing? 

The overall average is 36.5%, but it varies significantly by industry. Faith-based organizations average 45.5%, while retail sits closer to 37%. Compare your rate against your specific sector, not the general average.

What is the average ROI for email marketing? 

Most sources put it between $36 and $42 per $1 spent. The variation depends on methodology and who funded the study. The median ROI across independent studies is 122% — four times higher than other digital channels.

How many emails should a business send per month?

Most businesses send two to four times per month. No universal answer exists — frequency should be tested against your own list's unsubscribe and engagement patterns.

What is the difference between click-through rate and conversion rate? 

CTR measures how many recipients clicked a link. Conversion rate measures how many completed the intended action — a purchase, signup, or download. A high CTR with a low conversion rate often points to a landing page problem, not an email problem.

Is email marketing still effective in 2025 and 2026?

By most available measures, yes. 81% of companies use it, ROI remains strong relative to other channels, and the user base continues to grow. Effectiveness depends heavily on list quality, segmentation, and content relevance.
