Open Rates by Industry and Segment
Open rates remain a key engagement indicator, though privacy changes like Apple Mail Privacy Protection have inflated numbers since 2021. This section breaks down average open rates across industries and audience types to help you establish realistic performance targets. Keep in mind that inflated opens from MPP mean click-to-open rate and click rate are now more reliable engagement signals.
1
43.46% average email open rate across all industries in 2025
MailerLite's analysis of 3.6 million campaigns shows open rates increased from 42.35% in 2024, but Apple Mail Privacy Protection (MPP) inflates roughly 50% of reported opens, making click-to-open rate (CTOR) a more reliable engagement signal.
2
55.71% open rate for religion sector, highest performing industry
Religious organizations and nonprofits consistently outperform other sectors, with hobbies at 53.25% and nonprofits at 52.38%. These mission-driven audiences show higher engagement than retail and ecommerce, which average 30.10% to 32.67%.
3
42.35% average open rate in B2B email marketing
HubSpot's 2025 data shows B2B campaigns average slightly lower than the cross-industry baseline, with performance heavily influenced by subject line relevance, list quality, and send-time optimization rather than audience size.
4
32.67% open rate for e-commerce sector
Ecommerce and retail consistently rank in the lower-performing segment due to higher email frequency and broader audience lists. However, segmented ecommerce campaigns that use purchase history and browsing behavior see significant lifts in engagement.
5
6.81% average click-to-open rate (CTOR) in 2025
Click-to-open rate improved from 5.63% in 2024, making it a more reliable metric than open rate alone for measuring true engagement and content quality, especially for newsletters and promotional campaigns.
6
2.09% average click rate across all industries
Legal sector leads at 4.90% CTR, followed by manufacturing at 4.22% and media at 4.10%. Click rate depends heavily on CTA design, link placement, and content relevance; industries with fewer links naturally show lower rates regardless of engagement quality.
7
39.26% average open rate for ActiveCampaign customers in Q4 2025
ActiveCampaign's platform data represents a solid baseline of 30-40% for most industries, with top performers exceeding 40%. This benchmark reflects campaigns sent Jan-Dec 2025 and includes all customer verticals from SMBs to enterprises.
8
0.22% average unsubscribe rate in 2025, double 2024's rate
MailerLite found unsubscribe rates more than doubled year-over-year, primarily due to Gmail's one-click unsubscribe feature that lets users opt out without opening emails. Unsubscribe rates above 0.5% signal frequency, segmentation, or content-relevance issues.
Click Rates and Click-to-Open Rates by Industry
Click metrics reveal true engagement since they require deliberate action from recipients. Click-to-open rate (CTOR) is especially valuable as it shows how compelling your content is among those who actually opened your email. This section covers click performance across industries, showing the range from low-click sectors like beauty and retail to high-engagement verticals like B2B and legal services.
9
Legal industry achieves 4.90% click rate, highest among all sectors
According to MailerLite's analysis of 3.6 million campaigns, legal services lead in click-through performance, followed by manufacturing at 4.22% and media at 4.10%. This reflects higher audience intent and more targeted messaging in professional B2B verticals.
10
Manufacturing industry leads with 14.82% click-to-open rate
Manufacturing maintains the highest CTOR at 14.82%, demonstrating strong content relevance once emails are opened. Legal services follows closely at 14.72%, indicating that technical and industry-specific audiences engage deeply with relevant content.
11
Median click-to-open rate across all industries stands at 6.81%
MailerLite's 2025 data shows CTOR increased from 5.63% in 2024, indicating improved email content relevance across the board. This metric has become more valuable than open rates due to Apple Mail Privacy Protection inflation.
12
Average click rate across all industries is 2.09%
MailerLite analyzed 3.6 million campaigns and found click rates range from 0.83% at the low end to 4.90% for legal services. Retail and ecommerce consistently underperform, while B2B and nonprofit sectors exceed the average.
13
Politics and insurance industries show lowest click-to-open rates at 2.96% and 3.19%
Restaurants and cafes rank third lowest at 3.28% CTOR. These sectors face content relevance challenges, suggesting opportunities to improve messaging alignment and call-to-action placement for higher engagement.
14
Behavior-based emails achieve 25.5% click-to-open rate versus broadcast at 1.1%
Personalized, behavior-triggered emails dramatically outperform generic broadcasts in CTOR performance. This 24.4 percentage point gap demonstrates the critical importance of segmentation and relevance for driving clicks among engaged recipients.
15
Automated email flows deliver 5.58% click rate versus campaigns at 1.69%
Klaviyo's 2026 data shows automation significantly outperforms one-off campaigns in click performance. Flow-based emails achieve 3x higher click rates and 13x higher placed order rates, proving automation's value for engagement and revenue.
16
Interactive email elements increase click-to-open rate by 31.7%
MailerLite found that embedded surveys and interactive content boost CTOR significantly. Additionally, using embedded surveys instead of static call-to-action links generates 135% more total clicks, validating interactivity as a high-impact engagement lever.
Deliverability and List Health Metrics
Bounce rates, unsubscribe rates, and authentication standards directly impact whether your emails reach the inbox. This section covers hard bounces, soft bounces, spam complaint rates, and the impact of DMARC enforcement on inbox placement. Clean lists and proper authentication are foundational to strong campaign performance.
17
Only 60% of emails reach visible inboxes globally, despite 98.5% technical delivery rate
According to 2025 deliverability research, while email delivery rates appear strong at 98.5% (emails accepted by servers), actual inbox placement sits at only 60%, meaning 40% of technically delivered emails land in spam or other tabs. This gap reveals that technical delivery success dramatically overstates real reach by approximately 40%.
18
Hard bounce rate averages 0.21% while soft bounce rate averages 0.70% across industries
Updated 2025 data shows that hard bounces (permanent delivery failures from invalid addresses) average 0.21%, while soft bounces (temporary failures from full inboxes or server issues) average 0.70%. Knowing this split helps marketers distinguish between list quality problems and temporary delivery hiccups.
19
Average unsubscribe rate is 0.22% in 2025, more than double the 0.08% rate from 2024
MailerLite's analysis of 3.6 million campaigns found that unsubscribe rates surged from 0.08% in 2024 to 0.22% in 2025. This dramatic increase reflects stricter list hygiene practices and removal of inactive subscribers, which ironically improves overall deliverability even though raw unsubscribe counts rise.
20
Global inbox placement rate stands at 83.5%, with roughly 1 in 6 marketing emails never reaching inboxes
Validity's 2025 benchmark reveals that only 83.5% of emails worldwide reach visible inboxes, with 6.7% landing in spam and 9.8% going missing entirely. This means businesses sending 1,000 emails lose visibility on approximately 165 messages, representing a material revenue leak for ecommerce and retention campaigns.
21
Only 7.6% of domains enforce DMARC with p=quarantine or p=reject policies despite mandatory requirements
Despite Google and Yahoo requiring DMARC compliance for bulk senders since February 2024 and Microsoft enforcing it since May 2025, less than 8% of domains actually enforce strict DMARC policies. Even worse, 33.4% of the top 1 million internet domains lack valid DMARC records altogether, giving authenticated senders a 2.7x advantage in inbox placement.
22
Gmail and Yahoo require spam complaint rates below 0.3%, with 0.1% as the industry best practice threshold
Google and Yahoo enforce complaint rate thresholds at 0.3%, triggering aggressive filtering when exceeded. Leading email providers recommend maintaining complaint rates below 0.1% to protect sender reputation. Rates above 0.3% are classified as a deliverability emergency requiring immediate remediation.
23
Fully authenticated domains with SPF, DKIM, and DMARC enforcement achieve 85-95% inbox placement versus 47.14% for unauthenticated senders
Research from 2025 shows that organizations implementing complete authentication (SPF, DKIM, and DMARC enforcement) consistently reach 85-95% inbox placement rates, compared to just 47.14% for domains without authentication. This 38.76 percentage point gap demonstrates that authentication is the single strongest driver of inbox delivery, more impactful than any content or engagement optimization.
B2B vs. B2C Email Performance
Email marketing operates differently depending on audience type. B2B campaigns nurture longer sales cycles while B2C drives immediate purchases. This section compares open rates, click rates, and conversion rates between business and consumer segments, along with specific benchmarks for different automation types like welcome flows, abandoned cart, and browse abandonment.
24
B2B emails average 37.4% open rates while B2C messages reach 40% in 2025
Open rate differences between B2B and B2C reflect how each segment engages with email. B2B audiences focus on learning and problem solving while B2C prioritizes immediate offers and purchases. However, both are inflated by Apple Mail Privacy Protection, which now affects roughly 64% of Apple Mail users.
25
B2B click-through rates run 47% higher than B2C at 2.0% to 4.0% versus lower B2C rates
B2B recipients click with intent, evaluating solutions and comparing vendors, making each click more valuable. B2C clicks are often impulse-driven. This intent difference means B2B emails generate higher quality clicks that convert better downstream, though B2C still dominates on volume.
26
Email flows deliver 5.58% click rates and 13x higher placed order rates versus 1.69% for broadcast campaigns
Automated sequences triggered by behavior (signups, pricing page visits, downloads) dramatically outperform batch-and-blast campaigns. This represents one of the most significant performance gaps in email marketing, applicable to both B2B and B2C.
27
B2B emails achieve 15% click-to-open rate compared to 13% for B2C
This 2-percentage-point gap reflects higher engagement intent among B2B subscribers. When B2B recipients open an email, they're more likely to click through because they're actively evaluating information relevant to their role or business decision.
28
Mailchimp campaigns average 38.2% open rate in 2025, boosted by AI-powered send-time optimization
Mailchimp users benefit from AI-driven send-time optimization that identifies individual subscriber engagement windows. This surpasses the broader industry average and demonstrates how personalization technology lifts engagement. The rate remains inflated by Mail Privacy Protection.
29
Welcome emails and abandoned cart automations generate 50% open rate and 10-15% recovered revenue respectively
Welcome flows establish first impressions and set engagement tone, while abandoned cart sequences recover lost revenue. These automations represent some of the highest-performing email types across both B2B and B2C, with abandoned cart being particularly effective for ecommerce segments.
30
Email conversion rates average 1-5% across industries, with B2C at 2.8% and B2B at 2.4%
B2C campaigns show slightly higher conversion rates due to immediate purchase intent, while B2B conversions take longer but reflect higher deal value. Automated emails convert at significantly higher rates than campaigns, and personalized sequences boost all conversion metrics substantially.
31
Automated emails generate $2.87 per email sent versus $0.07 for campaign blasts, representing 40x revenue difference
This dramatic gap between automation and campaigns explains why email flows should be foundational to any B2B or B2C strategy. Behavioral triggers, lifecycle positioning, and optimal timing collectively drive revenue efficiency that broadcast campaigns cannot match.
Revenue and Conversion Metrics
Email ROI, revenue per recipient, conversion rates, and automation efficiency show email's bottom-line impact. This section covers email's return on investment compared to other channels, the revenue lift from segmentation and AI personalization, and how email flows outperform campaigns on efficiency and revenue generation.
32
$36 to $42 in ROI for every $1 spent on email marketing
Email consistently outperforms all other marketing channels. Industry research from multiple sources confirms this 3,600% to 4,200% return on investment, making email the highest-ROI channel available to most businesses.
33
2.6% average email conversion rate across all industries in 2025
While engagement metrics vary by industry, conversion rates cluster around 2.6% for standard email campaigns. However, well-optimized campaigns and automation flows significantly exceed this baseline.
34
Automated emails drive 320% more revenue than non-automated campaigns
Behavior-triggered flows like welcome series, abandoned cart, and post-purchase emails generate substantially higher per-recipient revenue than batch-and-blast campaigns, representing email's biggest ROI opportunity.
35
Segmented campaigns generate 760% more revenue than non-segmented sends
Proper audience segmentation based on behavior, demographics, and lifecycle stage dramatically increases revenue per send. This multiplier effect proves that targeting precision drives far greater ROI than sending volume.
36
AI-personalized emails generate 3.2x more revenue per recipient
When AI is applied across multiple layers (dynamic content, send-time optimization, predictive segmentation), the compounding effect lifts revenue per recipient by 3.2x compared to standard campaigns over a 12-week period.
37
Top 10% of email automation flows generate $7.79 RPR versus $0.11 for campaigns
Revenue per recipient varies dramatically between high-performing automation flows and standard campaigns. Top performers achieve nearly 18x the RPR of campaigns through sophisticated segmentation and personalization.
38
Post-purchase emails generate 90% more revenue per recipient than regular campaigns
Transactional and post-purchase email flows outperform promotional campaigns by delivering relevant follow-up offers and content when customers are most engaged and receptive.
39
Personalization increases email ROI by 260% compared to non-personalized sends
Brands implementing comprehensive personalization strategies across subject lines, content, and send timing see dramatically higher returns. This 260% lift demonstrates personalization's material impact on bottom-line revenue.
40
Abandoned cart emails recover 10-15% of lost purchases on average
Recovery flows specifically designed for cart abandonment convert at significantly higher rates than standard campaigns, directly contributing to incremental revenue recovery and improved overall email ROI.
Mobile, Device, and Send-Time Performance
Mobile dominates email consumption, with different reading patterns across devices affecting engagement. This section includes mobile open rates, responsive design impact, device-level click behavior, and optimal send times for higher engagement. Regional and time-based variations are also covered to help you optimize timing and design.
41
55% of email opens occur on mobile devices, with only 29% on desktop and 24% via webmail.
Mobile has become the dominant platform for email consumption. This shift requires marketers to prioritize mobile-first design and responsive templates to ensure emails display properly across varying screen sizes. Desktop users, while fewer in absolute numbers, still generate higher click-to-open rates.
42
Mobile users show 11% click-to-open rate versus 21% on desktop.
While mobile dominates opens, desktop users demonstrate nearly double the engagement when they do click. This reveals a critical insight: mobile drives visibility while desktop drives conversions. Marketers must optimize content for both audiences rather than assuming mobile opens translate to mobile action.
43
8 PM is the highest-performing send time for opens at 59%, followed by 2 PM at 45% and 11 PM at 40%.
Evening sends, particularly at 8 PM, significantly outperform traditional daytime windows. This pattern reflects how subscribers now check email outside traditional work hours, often during personal time. Regional and industry variations mean testing send times remains critical, but evening hours show surprising strength across datasets.
44
Tuesday and Thursday achieve the highest engagement, with Friday 6 PM showing strong alignment for high-value campaigns.
Mid-week sends (Tuesday through Thursday) between 9 AM and 3 PM remain industry standards for B2B audiences. However, newer data shows Friday late afternoon and evening windows gaining traction, particularly for consumer audiences. This reflects shifting work patterns and increased mobile checking during transition times.
45
Responsive email templates increase mobile click rates by 15%, lifting unique clicks from 2.7% to 3.1%.
Responsive design directly impacts bottom-line performance. Mobile-optimized emails see measurable click improvements, particularly on first three to five links. This demonstrates that investing in responsive templates and testing across devices pays immediate dividends in engagement, not just user experience.
46
75% of users delete non-mobile-optimized emails immediately.
Mobile experience quality directly determines whether subscribers engage or abandon. This statistic underscores that responsive design is not optional but essential for maintaining list health and campaign performance. Non-optimized emails face instant rejection before content is even evaluated.
47
Over 70% of emails are opened on mobile devices, and 80% of recipients delete emails that don't display properly.
The overlap between mobile dominance and poor rendering creates a compounding problem. When emails fail to render correctly on mobile, recipients don't just disengage, they actively delete and potentially mark as spam. This damage affects sender reputation and future deliverability alongside immediate performance loss.
48
Personalized mobile subject lines increase opens by 26%.
Mobile users respond strongly to personalization signals, particularly in subject lines where space is limited. This 26% lift shows that combining personalization strategies with mobile optimization creates compound effects. Mobile-specific subject line testing should be a standard practice.
