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 use email daily (Statista, 2025), and 41.6% of all opens happen on a mobile device (Litmus Email Client Market Share, 2025). The one most operators haven't priced in: automated messages account for roughly 41% of all email-driven orders while making up about 2% of sends (Omnisend, 2024).

Every number below carries a named source and a link. When you're done reading, put your own figures into the email marketing ROI calculator rather than assuming the averages describe your list.

General email usage

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, with a forecast of 4.89 billion by 2027 (Statista, 2025).

Daily volume tracks 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, and the split keeps tilting toward business mail.

Two more worth holding in your head: Apple Mail accounts for about 58% of tracked opens (Litmus Email Client Market Share, 2025), and four out of five marketers say they would rather give up social media than email (HubSpot State of Marketing, 2024).

The volume figure is the one that quietly shapes everything else. If your message lands beside a hundred others, you're fighting for attention well before you're fighting for conversion.

Email marketing ROI

ROI is where email defends its budget, and independent surveys have put the channel in the same range for five years running.

The exact 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 the highest-ROI channel across 6,000 marketers in 39 countries (Salesforce, 2024), and 87% of marketers in HubSpot's panel called email critical to business success (HubSpot, 2024).

Treat all of these as directional. Email ROI is typically calculated against platform cost, which is a tiny denominator; paid channels are measured against ad spend. For how the math actually works, see email marketing ROI, and for the head-to-head, email vs social media ROI. If you want the per-send version rather than the annual one, the revenue per email calculator is the faster check.

Open, click, and conversion benchmarks

The most-asked question in every operator Slack is what counts as a good open rate. The honest answer depends on your industry, your list hygiene, and whether Apple Mail Privacy Protection is inflating the number.

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 break the same metrics down by vertical, which is where the real variance lives.

Source: Mailchimp Email Marketing Benchmarks (2024). Mailchimp's averages pre-date Apple's privacy changes; GetResponse's 26.8% comes from a dataset that includes the inflation. Two caveats before you compare yourself to either: Apple Mail Privacy Protection pre-fetches images and registers an open whether or not anyone read the message, which Litmus estimated inflated reported opens by 8 to 15 points on the average list (Litmus, 2024), and click-through rate is now the more reliable engagement proxy for most senders.

For the strict formulas, see the glossary entries on open rate and click-through rate, then run your own numbers through the open rate, click rate, and click-to-open rate calculators. Segment-level benchmarks by industry are more useful than any cross-industry average, particularly for B2B SaaS and ecommerce senders whose lists behave nothing alike.

On conversion: Campaign Monitor puts the average email conversion rate at 1.22% across industries, with top-quartile senders at 3.71% (Campaign Monitor, 2024). Compare against your own with the conversion rate calculator.

On timing: Tuesday at 10:00 a.m. local is the most-cited best slot across benchmark studies, and it's also the most crowded. GetResponse's 2024 analysis found that emails sent at 4:00 and 5:00 a.m. local time posted higher open rates than the office-hours peak, most likely because those inboxes were less cluttered (GetResponse, 2024). Aggregate send time data by day and industry is a better starting point than any single headline hour.

Mobile

Mobile is where the opens happen, and where design decisions fail quietly if nobody 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 (Litmus, 2025)
• 39.1% occur in webmail (Litmus, 2025)
• 19.3% occur in desktop clients (Litmus, 2025)
• Apple iPhone alone accounts for 57.6% of total opens (Litmus, 2025)
• Gmail webmail accounts for 27.2% (Litmus, 2025)
• 15% of US consumers read email exclusively on a mobile device (Litmus, 2024)

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

Automation

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 analyzed 11.5 billion promotional emails and 1.5 billion automated messages across its 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 roughly an 18x revenue-per-send ratio against promotional broadcasts.

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

Two of those rows are worth building this month if you haven't. The welcome series and the cart recovery flow together account for most of the revenue in that table; working versions of both sit in the welcome swipe file and the abandoned cart swipe file, and the full sequence maps are in the ecommerce email flows library. For the build itself, see email marketing automation.

AI adoption

AI inside email workflows crossed the default-feature line this year. It's embedded in most mainstream compose surfaces rather than bolted on.

HubSpot's State of AI research surveyed more than 1,000 marketing professionals and found that 79% now use generative AI somewhere in their workflow, with email the second most common surface after social; 49% say AI helps them write more effective emails, and 43% use it specifically for subject-line generation (HubSpot, 2024).

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

Adoption figures say nothing about output quality, and that gap is where the next two years of the discipline get decided. For where this is heading, see the future of AI in email marketing.

Deliverability

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

• 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: 84.3%; Europe: 80.9%; Asia-Pacific: 78.4% (Validity, 2024)
• Nonprofit senders place highest at 88.2% (Validity, 2024)
• Consumer products senders place lowest at 76.1% (Validity, 2024)

Authentication adoption climbed sharply after Google and Yahoo's February 2024 bulk sender rules. Valimail's DMARC research recorded 79% of Fortune 500 domains publishing a valid DMARC record by Q4 2024, up from 58% in 2023, and roughly 5.7 million domains globally publishing DMARC by late 2024, up from 3.8 million in 2022 (Valimail, 2024). Google and Yahoo now reject or quarantine mail that fails authentication from senders above 5,000 messages a day, and Gmail treats a spam complaint rate above 0.3% as a filtering trigger (Google, 2024).

That 17% placement gap is the largest unfixed cost most senders carry, and almost nobody measures it. Check your own inbox placement rate before optimizing anything upstream of it; the email deliverability guide covers the authentication setup.

Regional variation matters when you plan expansion. APAC senders report 78.4% placement against 84.3% in North America (Validity, 2024), and B2B lists average a 15.1% open rate against 21.3% for B2C on Mailchimp's panel (Mailchimp, 2024).

Personalization

Salesforce's 2024 State of the Connected Customer surveyed 14,300 consumers globally; 65% said they would switch brands over poor personalization (Salesforce, 2024). Campaign Monitor's benchmark data puts personalized subject lines at 26% more likely to be opened (Campaign Monitor, 2024).

A warning about this category specifically: personalization is the most citation-laundered corner of email research. The famous multiples that circulate about segmented campaigns and dynamic content trace back through three or four blogs to a single unpublished vendor study, usually from before 2015. When you meet a personalization statistic that sounds too good, find the original report before you put it in a deck. Most of the time it isn't there.

List growth and churn

List health drives every downstream metric and gets a fraction of the attention that open rates do.

• Average email list churn from unsubscribes, hard bounces, and complaints runs 22 to 30% annually (HubSpot, 2024)
• 56% of subscribers unsubscribe because the content is no longer relevant (HubSpot, 2024)

A list shrinking 25% a year needs to grow 25% a year just to hold still, which is why acquisition and reactivation belong on the same dashboard as campaign performance. Track your list growth rate and churn rate monthly, and for reactivation tactics see how to re-engage inactive subscribers.
