Open rates are inflated by Apple’s privacy bots. Automated flows quietly out-earn manual campaigns by double digits. And Gmail, Yahoo, and Microsoft now reject unauthenticated mail outright. If you’re planning an email marketing strategy in 2026, the numbers you use to justify it need to hold up — which means citing the study behind them, not a blog that copied it.
This page pulls together the email marketing statistics that actually matter this year: ROI, open and click benchmarks, automation performance, deliverability, authentication, and security. Every figure links straight to the report that produced it, and where sources disagree — which happens often in email, because every platform measures its own customer base — we say so instead of quietly picking the flattering number.
Email Marketing Statistics 2026: Quick Answer
- Email marketing returns an average of $36 for every $1 spent, and brands using dedicated analytics tools see 43% higher ROI still (Litmus).
- The global average open rate sits at 19–21% excluding Apple’s privacy-inflated opens (Brevo, WebFX), but 30.7% across ecommerce specifically once Apple Mail is included (Omnisend).
- Automated emails generate roughly 16–18x more revenue per send than one-off campaigns (Omnisend, Klaviyo).
- Global inbox placement averages 87.2% — meaning roughly 1 in 8 marketing emails never reaches the inbox at all (Validity).
- An estimated 4.6 billion people use email worldwide, sending and receiving roughly 376 billion messages a day (Statista).
- Global DMARC adoption has reached 52.1% of top domains — but more than half of those still enforce zero spoofing protection (EasyDMARC).
Key Highlights
- 72% of marketers aren’t sure what the ROI of their email program actually is (Litmus).
- Advanced AI adopters are 75% more likely to achieve ROIs above 45:1 (Litmus).
- Apple Mail and Gmail together account for nearly 90% of all email opens worldwide (Litmus).
- Automations made up just 2% of email sends but drove 30% of email revenue in 2025 (Omnisend).
- The average cart abandonment rate is 70.22%, largely unchanged in a decade (Baymard Institute).
- Klaviyo’s top 10% of automated flows post revenue-per-recipient as high as $7.79 (Klaviyo).
- Fortune 500 companies have hit 95% DMARC adoption, versus far lower enforcement among smaller firms (EasyDMARC).
- The human element was present in 62% of confirmed data breaches, with email remaining the top social-engineering vector (Verizon).
Email Usage & Volume Statistics
Email isn’t being replaced — it’s still the backbone of digital communication, and its user base keeps growing even as new channels launch around it.
- The number of global email users is projected to reach approximately 4.6 billion — more than half the world’s population (Statista).
- The number of emails sent and received worldwide each day is projected to hit roughly 376.4 billion, up from 306.4 billion just a few years earlier (Statista).
- Only 12% of marketers worldwide allocate more than 15% of their total marketing budget to email, while 22% allocate less than 5% — a notably small investment for the channel’s return (Litmus, cited via eMarketer).
What this means: Email’s audience keeps expanding, but most teams are still under-resourcing it relative to what it returns. If you’re building a program from scratch, our guide to the best email marketing software is a reasonable place to start budgeting.
Email Marketing ROI Statistics
- Email marketing delivers an average ROI of around $36 for every $1 spent — still one of the highest of any owned marketing channel (Litmus).
- Brands using dedicated email analytics tools see 43% higher ROI than those relying on their ESP’s default reporting alone (Litmus).
- 72% of marketers say they aren’t sure what the actual ROI of their email program is — a measurement gap, not a performance gap (Litmus).
- 30% of brands plan to increase their overall email marketing spend this year (Litmus).
- Advanced AI adopters are 75% more likely to report ROIs above 45:1 than teams that haven’t integrated AI into their workflow (Litmus).
- Globally, marketers rate email as their top-ROI digital channel: 30% call it their highest-performing channel outright, and another 43% rate it medium-ROI (Omnisend).
- In a February 2025 survey of UK and US marketers, 26.9% said email delivered their best ROI of any channel — ahead of websites/blogs (22.7%), SEO (19.2%), paid search (16.1%), and social advertising (11.4%) (GetResponse, cited via eMarketer).
| Channel | Marketers naming it their best-ROI channel |
|---|---|
| Email marketing | 26.9% |
| Website / blog content | 22.7% |
| SEO | 19.2% |
| Paid search | 16.1% |
| Social media advertising | 11.4% |
What this means: The ROI story hasn’t changed — email still wins — but the measurement story has. If nearly three-quarters of marketers can’t confidently state their own ROI, that’s the bigger fix. Pairing your ESP with proper attribution matters more than chasing another point of open rate.

Email Open Rate Statistics
A methodology note before the numbers: ask five platforms for “the average open rate” and you’ll get five different figures — and all of them are technically correct. Apple’s Mail Privacy Protection (MPP) pre-loads tracking pixels for a large share of Apple Mail users regardless of whether the recipient opens the email, which inflates every open-rate benchmark published since 2021 to a different degree depending on how Apple-heavy that platform’s customer base is. Treat open rate as a directional signal, not a precise measurement, and weight click and revenue metrics more heavily.
- Brevo’s 2026 benchmark (175,000+ active senders) puts the average open rate at 21%, with an average CTR of 3.96%, unsubscribe rate of 0.15%, and bounce rate of 0.51% (Brevo).
- WebFX’s cross-industry dataset reports a 19.21% average open rate, 2.44% average CTR, 0.89% unsubscribe rate, and 2.48% bounce rate (WebFX).
- By industry, WebFX found government emails lead open rates at 30.5%, followed by nonprofits at 25.2% and education at 23.4% (WebFX).
- Ecommerce open rates (Apple MPP included) rose for the fifth consecutive year, climbing from 26.6% in 2024 to 30.7% in 2025 (Omnisend).
- Apple’s Mail Privacy Protection now impacts an estimated 55–60% of all email opens tracked globally (Litmus).
- Dark Mode is now used by more than 25% of the total email-reading user base, up from a fringe feature just a few years ago (Litmus).
Email Client Market Share (May 2026)
Litmus tracks live open data across more than a billion opens per month. Here’s how the inbox landscape actually breaks down right now:
| Email client | Market share |
|---|---|
| Apple (Mail, iPhone, iPad, MPP) | 64.66% |
| Gmail | 24.11% |
| Outlook (desktop) | 6.49% |
| Yahoo Mail | 2.57% |
| Google Android (non-Gmail apps) | 1.38% |
| Outlook.com (webmail) | 0.38% |
| Thunderbird | 0.21% |
What this means: Apple and Gmail alone account for close to 90% of opens, so rendering and privacy behavior on those two platforms should drive most of your testing priorities — not the long tail of niche clients.

Automation vs. Campaign Statistics
This is where the real performance gap in email marketing lives. Every major platform’s 2026 data agrees on the same pattern, even though they measure different customer bases.
- Across 183,000+ Klaviyo ecommerce accounts, automated flows generate nearly 41% of total email revenue from just 5.3% of sends, with revenue per recipient roughly 18x higher than one-off campaigns (Klaviyo).
- Nearly 48% of flow-driven email revenue comes from new buyers, compared with just 16% from campaigns — flows do the heavy lifting on first-purchase conversion (Klaviyo).
- The top 10% of email flows achieve a revenue-per-recipient as high as $7.79, with click rates exceeding 10% (Klaviyo).
- In Omnisend’s 2026 ecommerce report, automations made up just 2% of email sends yet drove 30% of email-attributed revenue — 16x more per send than scheduled campaigns (Omnisend).
- Each automated email earned an average of $2.87 per send, compared with $0.18 for scheduled campaigns (Omnisend).
- Automated messages delivered 24% higher open rates, roughly 6x stronger click engagement, and 19x higher conversion rates than manual campaigns (Omnisend).
- Abandoned-cart and welcome messages together drove 76% of all automation-generated orders in 2025 (Omnisend).
- Back-in-stock emails delivered the highest conversion rate of any automation type, at 6.46% (Omnisend).
- Birthday emails produced an average order value more than 4x higher than the typical send, at $744.37 (Omnisend).
- Click-to-conversion rates jumped 53% year-over-year, rising from 5.9% to 9% — fewer clicks, but far higher purchase intent behind each one (Omnisend).
What this means: If your program is 90% one-off campaigns and 10% automation, the data says you have that ratio backward. Building out welcome, abandoned-cart, and back-in-stock flows first — before investing more in campaign volume — is where the revenue actually is.
Ecommerce & Cart Abandonment Statistics
- The average online shopping cart abandonment rate is 70.22%, based on the Baymard Institute’s meta-analysis of 50 separate studies — a figure that has barely moved in over a decade (Baymard Institute).
- An estimated $260 billion in abandoned orders is recoverable in the US and EU alone through better checkout design (Baymard Institute).
- Nearly 1 in 5 shoppers have abandoned a cart specifically because the checkout process felt too long or complicated — a problem that’s typically fixable by trimming form fields (Baymard Institute).
- Well-timed cart-recovery and post-purchase flows are exactly why automated emails now generate 16–18x more revenue per send than manual campaigns, as shown above (Omnisend).

Deliverability Statistics
- The global average inbox placement rate reached 87.2% in 2025, a 3.7-point improvement year-over-year (Validity).
- Gmail — the largest mailbox provider at roughly 42.9% market share — achieved an inbox placement rate of 89.8% in 2025 (Validity).
- Microsoft/Outlook remained the toughest major mailbox provider, with inbox placement at just 77.4% (Validity).
- Industry-level inbox placement ranges from around 86% (education) up to 92% (B2B SaaS), a meaningful gap for programs sending at scale (Validity).
What this means: An 87% average inbox placement rate means roughly 1 in 8 marketing emails never reaches the primary inbox at all, regardless of open-rate reporting. Authentication (below) is the single biggest lever most senders haven’t fully pulled.
Email Authentication Statistics: SPF, DKIM, DMARC & BIMI
- Google and Yahoo require SPF, DKIM, and a published DMARC record for any domain sending more than 5,000 messages per day, with non-compliant mail rejected outright at the SMTP level (Google sender guidelines).
- Global DMARC adoption reached 52.1% of the top 1.8 million domains worldwide in early 2026, up from just 27.2% in 2023 (EasyDMARC).
- Of the domains with a valid DMARC record, more than half remain parked at p=none — the monitoring-only policy that provides zero actual protection against spoofing (EasyDMARC).
- Fortune 500 companies have reached 95% DMARC adoption, with more than 80% at true enforcement level (p=quarantine or p=reject) — a much stronger position than the broader Inc. 5000 dataset (EasyDMARC).
Why the discrepancy between reports: you’ll see DMARC adoption figures anywhere from 11% to 52% quoted across different studies in 2026. That’s not a contradiction — it’s a difference in scope. Studies analyzing the top 1.8 million domains by traffic (EasyDMARC) show much higher adoption than scans of the broader, long-tail domain universe. Always check the sample size and population before comparing two DMARC statistics directly.
Email Security & Phishing Statistics
- The human element was present in 62% of confirmed data breaches analyzed in 2026, up from 60% the year prior (Verizon Data Breach Investigations Report).
- Social engineering remained the third most common breach pattern overall, accounting for 16% of confirmed breaches, with email still the primary vector (Verizon).
- Mobile-based social engineering — fake texts and voice calls — now succeeds roughly 40% more often than traditional email phishing, a sign attackers are diversifying beyond the inbox (Verizon).
- Business Email Compromise losses reported to the FBI reached $2.77 billion across 21,442 complaints in a single year (FBI Internet Crime Complaint Center (IC3)).
What this means: Authentication isn’t just a deliverability checkbox anymore — properly configured SPF, DKIM, and DMARC are now a direct line of defense against the exact attack pattern (email-based social engineering) that shows up in the majority of real-world breaches.

Frequently Asked Questions
How many emails are sent each day?
Roughly 376.4 billion emails are sent and received worldwide every day, according to Statista‘s projections.
Is email marketing still effective in 2026?
What is the average email marketing ROI?
Around $36 per $1 spent on average, with teams using dedicated email analytics reporting 43% higher returns still (Litmus).
What is a good email open rate in 2026?
What is a good click-through rate (CTR)?
Cross-industry CTR averages fall between roughly 2.4% and 4% depending on the dataset (WebFX, Brevo). CTR and click-to-open rate are more reliable than open rate for judging real engagement — see our full CTR vs. CTOR breakdown.
Which industries have the best email performance?
Government and nonprofit senders consistently post the highest open rates — 30.5% and 25.2% respectively in WebFX’s dataset — largely because their audiences opt in with high intent (WebFX).
How often should businesses send marketing emails?
There’s no universal number in the primary research reviewed here, and frequency tolerance varies heavily by list and industry. What the data does show clearly is that automated, behavior-triggered sends (welcome, cart abandonment, back-in-stock) outperform scheduled blasts by a wide margin regardless of overall frequency (Omnisend).
Does personalization and automation actually increase conversions?
Is AI improving email marketing results?
What causes most cart abandonment, and can email fix it?
The average cart abandonment rate is 70.22%, and nearly 1 in 5 shoppers cite a checkout process that’s too long or complicated (Baymard Institute). Automated cart-recovery emails are one of the highest-converting automation types available, per Omnisend’s data.
What affects email deliverability the most?
Authentication (SPF, DKIM, DMARC), sender reputation, spam complaint rate, and list hygiene are the biggest levers. Global average inbox placement is 87.2%, meaning authentication gaps are still costing the average sender real inbox share (Validity).
How does Apple Mail Privacy Protection affect open rates?
MPP automatically pre-loads tracking pixels for a large share of Apple Mail users, whether or not they actually open the email. Litmus estimates it now affects 55–60% of all tracked opens globally, which is why open rate alone is no longer a reliable performance metric (Litmus).
What is BIMI, and do I need it?
BIMI (Brand Indicators for Message Identification) displays your verified logo next to your emails in supporting inboxes. It requires DMARC enforcement (p=quarantine or p=reject) as a prerequisite, which is one reason overall BIMI adoption still trails basic DMARC adoption significantly (EasyDMARC).
What are Gmail and Yahoo’s bulk sender requirements?
Any domain sending more than 5,000 messages per day to Gmail or Yahoo addresses must authenticate with SPF and DKIM, publish a DMARC record, keep spam complaints low, and support one-click unsubscribe — non-compliant mail is rejected outright (Google sender guidelines).
Is email still riskier from a security standpoint than other channels?
Email remains the primary vector for social engineering, which was involved in 16% of confirmed breaches, and the human element featured in 62% of all breaches analyzed (Verizon). Proper authentication meaningfully reduces this exposure.
Which email marketing platform is “best”?
It depends on your use case — ecommerce automation, B2B nurture, and simple newsletters all favor different tools. See our comparisons of ActiveCampaign vs. HubSpot and our best email marketing software roundup for a full breakdown.
How many people still check email daily?
With an estimated 4.6 billion global email users, email remains one of the most habitually checked digital channels, and daily send/receive volume continues to climb year over year (Statista).
