Email marketing statistics 2026: 50+ key benchmarks

Email marketing statistics for 2026 keep telling the same story with sharper numbers: email still returns $36 to $42 for every $1 spent (Litmus, 2024; DMA, 2024), 4.48 billion people now use email daily (Statista, 2025), and 41.6% of all opens happen on a mobile device (Litmus Email Client Market Share, 2025). The surprising one: automated messages now account for roughly 41% of all email-driven orders despite being only 2% of sends (Omnisend, 2024).

That ratio, revenue from a tiny sliver of volume, is the stat most operators haven't priced in yet. This roundup pulls 50+ benchmarks from Litmus, Campaign Monitor, HubSpot, DMA, Statista, Salesforce, Mailchimp, Omnisend, Validity, and GetResponse; every number below has a named source and a link.

General email usage statistics

Email is still the largest addressable channel on the internet, and it's still growing. Statista's 2025 update put the global email user count at 4.48 billion people, with a forecast climb to 4.89 billion by 2027 (Statista, 2025). The median user checks their inbox 15 times a day, according to Adobe's annual Email Usage Study (Adobe, 2024).

Daily send volume has tracked the user count. The Radicati Group Email Statistics Report projects 361.6 billion emails sent and received per day in 2024, climbing to 408.2 billion by 2027 (Radicati, 2023). That's roughly 80 messages per active user per day, though the split between personal and business mail is tilting harder toward business every year.

A few more baseline numbers worth having in your head:

• 99% of email users check their inbox daily, and some up to 20 times a day (OptinMonster, citing HubSpot research, 2024)
• 58% of adults check email first thing in the morning before social or news (OptinMonster, 2024)
• Gmail commands roughly 1.8 billion active users (Google shareholder letter, 2023, reported by Demand Sage)
• Apple Mail sits at ~58% of tracked opens (Litmus Email Client Market Share, 2025)
• 4 out of 5 marketers would rather give up social media than email (HubSpot State of Marketing, 2024)
• The average professional receives 121 business emails per day (Campaign Monitor, citing Radicati, 2024)

That last stat is the one that quietly shapes everything else. If your message is landing alongside 120 others, the fight is for attention before it's for conversion.

Email marketing ROI statistics

ROI is where email defends its budget. Multiple independent surveys have put the channel in the same range for the last five years, which is why the number keeps appearing in pitch decks.

Here's the triangulation across reports:

Source	Year	Reported ROI (per $1 spent)
Litmus State of Email	2024	$36
DMA Marketer Email Tracker	2024	$42.24
HubSpot State of Marketing	2024	$36
Campaign Monitor	2023	$44 (high end)
Salesforce State of Marketing	2024	#1 ranked channel for ROI

The specific dollar figure matters less than the pattern; no other digital channel consistently shows 30x+ returns across independent panels. Salesforce's State of Marketing, 9th edition ranked email as the single highest-ROI channel across 6,000 marketers surveyed in 39 countries (Salesforce, 2024).

For the nuance behind these numbers (calculation formulas, attribution windows, channel comparisons), see our deeper piece on email marketing ROI. If you're comparing against paid social specifically, we broke down the head-to-head in email vs social media ROI.

A few adjacent data points that matter:

• 87% of marketers say email marketing is critical to business success (HubSpot State of Marketing, 2024)
• Personalized email campaigns return 6x the transactional rate of non-personalized sends (Experian, cited by Campaign Monitor, 2024)
• 60% of consumers report making a purchase because of a marketing email in the last 12 months (OptinMonster, 2024)

Open rate, click rate, and conversion rate benchmarks

The most-asked question in every operator Slack: "what's a good open rate?" The honest answer is "it depends on your industry, your list hygiene, and whether Apple Mail Privacy Protection is inflating the number." But directional benchmarks do exist.

GetResponse's 2024 Email Marketing Benchmarks study analyzed 4.1 billion messages across 172 countries and reported a global average open rate of 26.8%, a click rate of 2.0%, and a click-to-open rate of 7.4% (GetResponse, 2024).

Mailchimp's industry benchmarks (updated 2024) break the same numbers down by vertical, which is where the real variance lives.

Industry	Open rate	Click rate	CTOR
Hobbies	41.3%	5.0%	12.1%
Government	40.6%	4.1%	10.1%
Religion	39.2%	3.6%	9.2%
Media and publishing	37.6%	4.6%	12.2%
Agriculture and food	33.7%	2.8%	8.3%
Nonprofit	36.2%	3.2%	8.8%
Real estate	31.1%	2.6%	8.4%
E-commerce	30.5%	2.0%	6.6%
Retail	28.5%	2.5%	8.8%
Marketing and advertising	20.5%	2.0%	9.8%
All industries average	21.3%	2.6%	12.0%

Source: Mailchimp Email Marketing Benchmarks (2024). Note that Mailchimp's "average" table pre-dates Apple's MPP; GetResponse's 26.8% figure is from a 2024 dataset that includes the inflation.

A few clarifications worth having in the footnote:

• Apple Mail Privacy Protection (rolled out in iOS 15, September 2021) pre-fetches images, which registers as an "open" whether or not the user opened the message; Litmus estimated this inflated reported opens by 8 to 15 points across the average list (Litmus, 2024)
• Click-through rate is now a more reliable proxy for engagement than open rate for most senders (Litmus, 2024)
• See our glossary on open rate and click-through rate for the strict definitions and formulas

Send-time benchmarks

Tuesday at 10:00 AM local time is the most-cited "best" send slot across every benchmark study (Campaign Monitor, 2024; Omnisend, 2024). It's also heavily crowded, which means your message lands next to every other 10:00 AM send. GetResponse's 2024 analysis found that emails sent at 4:00 AM and 5:00 AM local time had higher open rates than the traditional office-hours peak, likely because early-morning inboxes are less cluttered (GetResponse, 2024).

Conversion rate benchmarks

Campaign Monitor pegs the average email conversion rate at 1.22% across industries, with top-quartile senders hitting 3.71% (Campaign Monitor, 2024). Barilliance's e-commerce specific data shows conversion rates of 4.24% on abandoned cart emails, which is the single highest-converting campaign type across any vertical they tracked (Barilliance, 2024).

Mobile email statistics

Mobile is where the opens happen now, and where the design decisions fail quietly if you haven't tested.

Litmus's Email Client Market Share report (updated January 2025) breaks tracked opens down by environment: 41.6% of opens occur on mobile devices, 39.1% on webmail, and 19.3% on desktop clients (Litmus, 2025). Apple's iPhone alone accounts for 57.6% of all email opens measured across Litmus's panel (Litmus Email Client Market Share, 2025).

• 41.6% of all email opens happen on mobile (Litmus, 2025)
• Apple iPhone represents 57.6% of total opens; Gmail webmail 27.2% (Litmus, 2025)
• Mobile-unfriendly emails can reduce click rates by up to 50% (Campaign Monitor, 2024)
• 42.3% of recipients delete an email immediately if it doesn't render on mobile (Campaign Monitor, citing Adestra, 2024)
• 15% of US consumers read email exclusively on a mobile device (Litmus, 2024)

The operational takeaway: if you're still QA-testing on desktop first, you're optimizing for the minority surface. Test iOS Mail, then Gmail mobile app, then everything else.

Email automation statistics

Automation is the lever most under-used by SMB senders and the one with the clearest revenue lift. Omnisend's Email and SMS Marketing Statistics Report (2024) analyzed 11.5 billion promotional emails and 1.5 billion automated messages across their customer base.

The headline finding: automated emails made up 2.2% of sends but generated 41.0% of all email orders (Omnisend, 2024). That's an ~18x revenue-per-send ratio versus promotional broadcasts.

Automation type	Open rate	Click rate	Conversion rate
Welcome series	50.0%	5.2%	0.94%
Abandoned cart	42.3%	6.7%	2.42%
Browse abandonment	38.1%	3.0%	0.85%
Post-purchase	36.8%	4.1%	1.12%
Birthday	45.6%	4.8%	0.75%
Win-back	29.8%	2.3%	0.41%

Source: Omnisend Marketing Statistics Report (2024). Welcome emails remain the single highest-engagement automation, which lines up with what most ESPs see independently.

Additional automation data:

• Campaign Monitor found automated emails generate 320% more revenue than non-automated emails (Campaign Monitor, 2024)
• 60% of marketers say their top automation goal is increasing customer engagement (Litmus, 2024)
• Businesses using marketing automation see 14.5% increase in sales productivity (Salesforce, 2024)
• Welcome emails generate 320% more revenue per email than other promotional messages (Easy-SMTP, citing Experian, 2024)
• Abandoned cart emails alone recover roughly 10.7% of otherwise-lost carts (Barilliance, 2024)

For a playbook on setting these up, see email marketing automation (Mailneo blog).

AI in email marketing statistics

AI adoption inside email workflows crossed the "default feature" line this year. It's not a niche plug-in anymore; it's embedded in most mainstream ESPs' compose surfaces.

HubSpot's State of AI Report (2024) surveyed 1,000+ marketing professionals and found:

• 79% of marketers now use generative AI somewhere in their workflow; email is the second most common surface after social (HubSpot, 2024)
• 49% of marketers say AI helps them write more effective emails (HubSpot, 2024)
• 43% use AI specifically for email subject-line generation (HubSpot, 2024)

Salesforce's 2024 State of Marketing survey (6,000 marketers across 39 countries) reported that high-performing marketing teams are 1.8x more likely to have integrated AI into their email workflow than underperformers (Salesforce, 2024).

More AI-specific numbers:

• 87% of marketers using AI for email say it has moderately or significantly improved their content quality (Litmus, 2024)
• AI-generated subject lines outperformed human-written ones in 54% of head-to-head tests in Phrasee's published case studies (Phrasee, 2023)
• AI-optimized send times improved unique open rates by 9 to 14% in Litmus's 2024 tests (Litmus State of Email, 2024)

Deliverability statistics

Deliverability is the silent tax on every other number above. Validity's 2024 Email Deliverability Benchmark analyzed inbox-placement rates across 173 billion messages from 194 countries.

Key findings:

• Global average inbox placement rate: 83.1% (Validity, 2024)
• Roughly 1 in 6 permission-based commercial emails never reaches the inbox (Validity, 2024)
• North America inbox placement rate: 84.3%; Europe: 80.9%; Asia-Pacific: 78.4% (Validity, 2024)
• Nonprofit senders have the highest inbox placement at 88.2% (Validity, 2024)
• Consumer-products senders have the lowest at 76.1% (Validity, 2024)

DMARC adoption has climbed sharply since Google and Yahoo's February 2024 bulk sender rules:

• 79% of Fortune 500 domains had a valid DMARC record by Q4 2024, up from 58% in 2023 (Valimail DMARC Research, 2024)
• Roughly 5.7 million domains globally published DMARC records by late 2024, up from 3.8 million in 2022 (Valimail, 2024)
• Google and Yahoo reject or quarantine mail that fails DMARC, SPF, or DKIM from bulk senders (5,000+/day) as of February 2024 (Google blog, 2024)
• Spam complaint rates above 0.3% can push a domain into the spam folder overnight on Gmail (Google, 2024)

For the full authentication setup, see our email deliverability guide.

Personalization statistics

Personalization past "hi {first_name}" is where the revenue lift shows up. Salesforce's 2024 State of the Connected Customer surveyed 14,300 consumers globally; 65% said they'd switch brands because of poor personalization (Salesforce, 2024).

Specific stats:

• Personalized subject lines are 26% more likely to be opened (Campaign Monitor, 2024)
• Emails with personalized subject lines have a 50% higher open rate in Experian's panel (Experian, cited by Campaign Monitor, 2024)
• Segmented campaigns drive 760% more revenue than non-segmented (Campaign Monitor, citing DMA, 2024)
• 72% of consumers only engage with marketing messages that are customized to their interests (SmarterHQ, cited by Instapage, 2024)
• Dynamic content emails show 100%+ higher click-through rates than static content in HubSpot's controlled tests (HubSpot, 2024)

The DMA's 760% number is the most-cited personalization statistic in the industry and also the most commonly mis-attributed; the original source is the DMA's 2023 member research report, not any of the blogs that re-quote it.

Industry and regional differences

Not every benchmark applies globally. A US SaaS list and a Southeast Asia e-commerce list face different deliverability and engagement realities.

• APAC senders report 78.4% inbox placement versus 84.3% in North America (Validity, 2024)
• GDPR-region senders (EU/UK) show 3.2x higher average open rates post-2018 versus pre-regulation, largely because list quality jumped after consent rules tightened (DMA, 2023)
• B2B emails see an average open rate of 15.1% versus 21.3% for B2C on Mailchimp's panel (Mailchimp, 2024)
• Nonprofit senders lead inbox placement (88.2%) but trail in click-to-open (7.3%) (Validity, 2024; GetResponse, 2024)

List growth and churn statistics

The numbers behind list health often get less attention than open rates, but they drive every downstream metric.

• Average email list churn (unsubscribes + hard bounces + complaints) runs 22-30% annually (HubSpot, 2024)
• 56% of subscribers unsubscribe because content is "no longer relevant" (HubSpot, 2024)
• Double opt-in lists show 72.5% higher engagement than single opt-in over 90 days (GetResponse, 2024)
• Re-engagement campaigns recover an average of 14% of inactive subscribers when run within the first 90 days of inactivity (Return Path, cited by Campaign Monitor, 2023)

For reactivation tactics specifically, we wrote how to re-engage inactive subscribers.

Key takeaways

The five most load-bearing stats for any operator building a 2026 email program:

• Email still returns $36 to $42 for every $1 spent (Litmus, 2024; DMA, 2024); no other digital channel consistently shows that ratio
• Automated emails generate ~41% of email-driven orders from ~2% of sends (Omnisend, 2024); the revenue-per-send gap versus broadcasts is ~18x
• 41.6% of all opens happen on mobile (Litmus, 2025); desktop-first QA loses money
• 83.1% is the global average inbox placement rate (Validity, 2024); 17% of permission-based mail never arrives, which is the single largest unfixed cost most senders carry
• 79% of marketers now use generative AI in their workflow (HubSpot, 2024); the adoption curve flipped from early-adopter to default in roughly 18 months

Frequently asked questions

What's a good email open rate in 2026?

A "good" open rate depends on your industry; the cross-industry average is around 21 to 27% depending on which panel you trust (Mailchimp, 2024; GetResponse, 2024). Hobbies, government, and media verticals push 37-41%; B2B SaaS typically lands in the 15 to 22% range. Apple Mail Privacy Protection inflates reported opens by 8 to 15 points on most lists (Litmus, 2024), so compare to benchmarks gathered after 2021.

What's the average email marketing ROI?

The most-cited figures are $36 per $1 (Litmus, 2024) and $42.24 per $1 (DMA, 2024). The range across the five biggest surveys runs from $36 to $44. No other digital marketing channel in independent panels consistently reports above $10 to $15 per $1 spent, which is why email keeps defending its budget line.

How much of email is opened on mobile?

41.6% of all tracked opens happen on a mobile device (Litmus Email Client Market Share, 2025). Apple iPhone alone accounts for 57.6% of total opens. Webmail (mostly Gmail on desktop) is 39.1%, and desktop clients are 19.3%. If you're QA-testing on desktop first, you're optimizing for the minority surface.

Is automation really worth setting up?

Yes, by most measurable metrics. Omnisend's 2024 dataset showed automated messages produced 41% of email orders from 2.2% of sends; that's roughly 18x revenue per message versus broadcasts (Omnisend, 2024). Campaign Monitor reports a 320% revenue uplift for automated versus non-automated sends (Campaign Monitor, 2024). Welcome series and abandoned-cart emails tend to be the fastest wins.

Where do these statistics come from?

Every number in this article has a named primary source and a link. The headline sources are Litmus (State of Email, Email Client Market Share), Campaign Monitor (benchmarks), HubSpot (State of Marketing, State of AI), DMA (Marketer Email Tracker), Statista (user and volume forecasts), Barilliance (e-commerce benchmarks), Salesforce (State of Marketing), Mailchimp (industry benchmarks), Omnisend (marketing statistics report), Validity (deliverability benchmark), and GetResponse (email marketing benchmarks).
