Global email marketing performance has reached new levels as of 2025-2026. These headline statistics establish the baseline for email open rates across all industries, providing context for understanding whether your campaigns are performing above, at, or below market averages. Data sources include analysis of over 3.3 million email campaigns from hundreds of thousands of accounts.
MailerLite's benchmark report, based on analysis of over 3.6 million email marketing campaigns, recorded the global average open rate at 43.46% in 2025, up from 42.35% in 2024. This year-over-year increase reflects both genuine engagement improvements and continued influence from Apple Mail Privacy Protection auto-prefetching.
Data sampled from over 3.3 million email marketing campaigns puts the widely-cited cross-platform baseline open rate at 42.35%. This figure is referenced by HubSpot, ActiveCampaign, and MailerLite as the foundational benchmark for evaluating campaign performance across all sectors.
GetResponse's annual benchmark report, analyzing 4.4 billion messages from customers with at least 500 contacts, found a global average open rate of 39.64%. This is a more conservative figure than MailerLite's dataset and reflects differences in platform audience mix and MPP filtering methodology.

According to a 2025 Email Benchmarking Report cited by Braze, B2C emails outperform B2B with a 40% average open rate compared to 37.4% for B2B messages. Consumer audiences tend to engage more readily with brands they have opted in to hear from, particularly in retail and travel sectors.
Regional benchmarks from MailerLite's 2025 study show a 15.72 percentage point gap between the highest and lowest-performing regions. High iPhone ownership in Australia, the US, and Canada inflates reported open rates via Apple MPP, while lower device penetration and a preference for messaging apps in LATAM and Asia suppress open rate figures.
According to Litmus data cited by EmailTooltester, Apple Mail held a 49.29% share of all email opens as of January 2025. Because Apple's Mail Privacy Protection pre-loads emails on proxy servers regardless of whether the recipient actually opens the message, nearly half of all reported opens are potentially inflated by automated pixel fires.
Since Apple's Mail Privacy Protection launched in September 2021, reported open rates have in some cases nearly doubled from around 22% to 40%, according to SalesSo's 2025 analysis. This artificial inflation means open rates should be treated as a directional signal for deliverability, not a precise measure of genuine subscriber engagement.
Omnisend's 2026 Ecommerce Marketing Report found the overall average email open rate for ecommerce merchants at 30.70%, significantly below the broader cross-industry average of 42.35%. The gap is driven by higher send frequency, promotional content saturation, and inbox fatigue common in ecommerce email programs.

Email performance varies dramatically across industries. Religious organizations, hobbies, and nonprofits significantly outperform retail and ecommerce sectors. Understanding your specific industry benchmark is critical for setting realistic goals and identifying optimization opportunities, as comparing across sectors often provides misleading performance signals.
MailerLite analyzed over 3.6 million campaigns from 181,000+ accounts to arrive at this figure. The year-over-year increase reflects a combination of improved list hygiene practices and the continued inflation effect of Apple Mail Privacy Protection, which pre-loads emails and registers opens without a human actually viewing the message. Marketers should treat this number as a directional benchmark rather than an absolute measure of engagement.
Faith-based organizations hold the top spot for email open rates, followed by hobbies at 53.25% and nonprofits at 52.38%. These three sectors have held the same top-three ranking for two consecutive years. The common thread is audience passion: subscribers in these categories actively seek out and value the communications they receive, which drives consistently strong open performance.
Travel and transportation sits at the bottom of the open rate rankings, followed closely by e-commerce at 32.67% and publishing at 34.24%. High send frequency, promotional fatigue, and competitive inboxes in these verticals all contribute to suppressed open rates. Marketers in these sectors should focus on segmentation and behavioral triggers to recover engagement.
Health and fitness campaigns achieve a 47.81% open rate, well above the all-industry median of 43.46%. Consulting follows at 45.96%, and nonprofits at 52.38%. These categories share a motivated subscriber base with strong personal relevance, which translates directly into higher open rates compared to retail or publishing audiences.

Different email types drive vastly different results. Automated emails, welcome series, and behavioral triggers substantially outperform newsletters and broadcast campaigns. Click-to-open rates (CTOR) and click-through rates (CTR) provide more reliable engagement indicators than open rates alone, especially given privacy tracking changes.
Based on MailerLite's analysis of over 3.6 million campaigns, the median open rate rose slightly from 42.35% in 2024 to 43.46% in 2025. These figures are inflated by Apple Mail Privacy Protection, which pre-loads email pixels before a recipient actually opens the message, so open rate should be treated as a directional signal rather than a precise engagement measure.
MailerLite's 2025 benchmark data shows CTOR rose by more than a full percentage point year-over-year. Because CTOR measures clicks only among people who actually opened the email, it is a more reliable indicator of content relevance and design effectiveness than open rate alone, especially in a post-Apple MPP environment.
GetResponse benchmark data shows welcome emails far outperform every other email category. Triggered at the moment of highest subscriber intent, welcome emails benefit from immediate relevance and the expectation subscribers have when they first opt in. By comparison, newsletters averaged a 40.08% open rate in the same dataset.
GetResponse data shows that behavioral trigger emails outperform newsletter CTR by roughly 31%. Triggered emails arrive in response to a specific subscriber action, so the content is inherently more relevant, which translates directly into more clicks. For teams measuring true engagement, CTR on triggered campaigns is a stronger north star than open rate.
Apple's Mail Privacy Protection automatically pre-loads email content and images for Apple Mail users, registering an open even when the email was never viewed. A study of over 80,000 email marketing accounts found open rates jumped 18 points in the six months after MPP launched. With nearly half of all email clients affected, reported open rates are materially overstated for most senders.

Apple Mail Privacy Protection (MPP) has fundamentally altered how marketers interpret open rate data since 2021. With Apple Mail accounting for nearly 46-51% of email opens, MPP auto-loads tracking pixels and inflates reported open rates by an estimated 18 percentage points. Understanding this distortion is essential for accurate performance assessment.
According to Litmus email client market share data, Apple Mail held nearly half of all tracked email opens at the start of 2025. Because MPP auto-fires tracking pixels for every Apple Mail user with the feature enabled, this level of market dominance means close to half of every reported open in a typical campaign is potentially machine-generated rather than a real human read.
Omeda analyzed roughly two billion emails sent before and after MPP rolled out in September 2021. Total open rates climbed from 22.6% to 40.5% within six months, while click rates stayed flat, confirming that the surge was driven entirely by machine-triggered pixel fires and not by genuine subscriber engagement.
Pushwoosh and HubSpot both cite the same figure: MPP's automatic content preloading inflates reported open rates by as much as 18 points for senders with typical audience distributions. For a campaign reporting a 42% open rate, the actual human-read rate could be closer to 24%, making open rate a deeply unreliable standalone KPI.
Validity's analysis of 2024 pixel-firing data found that Apple's proxy server was responsible for nearly three quarters of all open-tracking events, far ahead of every other email reading environment combined. This confirms that by 2024, the majority of what ESPs log as 'opens' are Apple machine events, not deliberate subscriber actions.

B2B email marketing shows distinct patterns from consumer campaigns. Cold email benchmarks for 2026 reveal significantly higher expectations (40-65% open rates), while traditional B2B newsletters average 37.4%. These higher benchmarks reflect more targeted list building and engagement-based sending practices in the B2B space.
According to the 2025 Email Benchmarking Report cited by Braze, B2B emails average a 37.4% open rate while B2C messages sit closer to 40%. The gap reflects that consumer audiences tend to engage more frequently with brands they have actively chosen to follow, particularly in retail and travel.
Year-over-year data shows B2B open rates climbing steadily, with a 2.5 percentage point gain between 2024 and 2025. This upward trend coincides with wider adoption of email authentication standards and more targeted list-building practices across B2B teams.
Industry context drives a wide spread in cold email performance. Well-executed campaigns in sectors where email is the primary communication channel, such as energy management, outperform tech-heavy verticals like SaaS by nearly 20 percentage points.
Analysis of billions of cold email interactions tracked by Instantly's Benchmark Report shows a meaningful decline in cold outreach open rates over two years. The drop reflects both inbox saturation and tighter spam filtering, reinforcing that raw volume strategies are losing effectiveness.
Data from 939 B2B companies using platforms like HubSpot, Outreach, and Salesloft shows a clear tiering by relationship stage: cold outreach averages 16.5%, warm leads reach 27.5%, and emails to existing customers hit 37.5%. The gap between cold and customer email performance is more than 21 percentage points.

List quality and segmentation drive dramatic performance improvements. Segmented campaigns generate 30% higher open rates and 50% increased click-through rates compared to broadcast emails. Personalization beyond names can lift open rates by up to 27% and boost revenue per send significantly across industries.
Mailchimp data shows that sending targeted content to defined audience segments produces dramatically higher engagement than broadcast emails. This performance gap makes list segmentation one of the highest-ROI tactics available to email marketers, regardless of industry or list size.
GetResponse benchmark data from campaigns across all industries shows personalization in the email body correlates with a 5+ percentage point lift in open rates and a lower bounce rate (2.26% vs. 2.50%). While personalization attracts more opens, marketers should pair it with relevant content to also drive clicks.
Campaign Monitor research, citing DMA data, found that segmented and targeted email campaigns can generate 760% more revenue than one-size-fits-all blasts. More than 76% of marketers say basic segmentation is already part of their email strategy, yet the revenue gap between segmented and unsegmented senders remains enormous.
Consistent across Campaign Monitor and Experian research, adding a personalized element to the subject line, such as the recipient's name, company, or a behavior-based reference, increases the probability of an open by 26%. Despite this, only around 65% of marketing professionals regularly use personalized subject lines.
DMA research shows that the majority of email-driven revenue comes from targeted sends, not mass campaigns. Combined with list segmentation, personalization and triggered workflows concentrate revenue into a small share of total email volume, making list quality a direct driver of email program profitability.

A good email open rate depends heavily on industry and context. Generally, above 30% is solid performance, 35-40% is strong, and 45%+ indicates exceptional engagement. However, these benchmarks must account for Apple Mail Privacy Protection inflation. For B2B, 37-44% is typical. For ecommerce, 30-32% is more realistic. Focus on comparing against your own historical performance and your specific industry, rather than broad averages.
Open rates are less reliable than they appear in 2025-2026. MPP auto-loads tracking pixels for Apple Mail users (46-51% of opens), inflating reported rates by approximately 18 percentage points. Smart marketers now prioritize click-through rates (CTR), click-to-open rates (CTOR), and conversion metrics as more accurate engagement indicators. Use open rates directionally for internal A/B testing, but pair them with downstream metrics for true performance assessment.
Religion and faith-based organizations lead with 59.70% open rates, followed by hobbies at 53.33% and nonprofits at 53.21%. Government sectors average 30.5%, while ecommerce and retail typically range from 30.70% to 35.90%. These variations reflect audience engagement levels, email frequency norms, and content relevance within each sector.
Segmented email campaigns drive 30% higher open rates and 50% more click-throughs compared to non-segmented broadcasts. Personalized subject lines boost opens by approximately 27%. Advanced segmentation based on behavior, demographics, and purchase history can increase open rates by up to 65%. Automation and journey-based personalization generate 320% more revenue than non-automated emails.

The financial sector outperforms many industries on both open rate and deliverability, largely because strict compliance practices and sophisticated list segmentation keep send quality high. About 38% of financial email marketers operate at the highest segmentation levels, which contributes to this exceptional combination of inbox placement and audience engagement.
Healthcare organizations outperform the cross-industry median, with drip campaigns in the sector reaching 56.36% view rates compared to 36.23% for general marketing emails in the same vertical. The utility-driven nature of healthcare communications, including appointment reminders and health updates, is the primary driver of this performance gap over promotional content.
B2B campaigns run slightly below the overall industry median but deliver more consistent performance quarter over quarter. B2B audiences open emails for information, comparison, and problem-solving rather than promotional offers, which means open rates tend to be stable but clicks require more nurturing. Click-through rate is a more reliable engagement signal than open rate in this context.
Klaviyo's benchmark data, drawn from ecommerce-focused senders, sits lower than general-purpose ESP averages because the platform skews toward high-frequency retail and direct-to-consumer brands. The gap between the median (31%) and the top decile (45.1%) shows how much segmentation, list quality, and automation sophistication can move open rate performance within the same industry.
E-commerce sits near the bottom of the open rate rankings at 32.67%, more than 20 percentage points below religion and nearly 15 points below health and fitness. High send frequency, heavy promotional positioning, and broad list composition all suppress open rates in this sector. Automated flows significantly outperform campaign sends in e-commerce, with flow-based emails generating click rates more than 3 times higher than one-off campaigns.

MoEngage's Email Benchmarks Report shows a stark gap between email types: behavior-triggered campaigns reach open rates of up to 42.36%, while generic broadcast emails fall between 14.5% and 26.9%. The data shows that personalization built around real user actions, such as browsing behavior or purchase history, can more than double open rate performance compared to batch-and-blast sends.
Litmus data cited in 2025 reporting highlights the outsized revenue contribution of automation relative to send volume. Automated flows such as welcome sequences, abandoned cart reminders, and post-purchase follow-ups convert at much higher rates than broadcast campaigns precisely because they reach subscribers at the right moment in the customer journey.
Klaviyo benchmark data shows abandoned cart emails are among the highest-performing automated email types across all three key engagement metrics. Top-performing brands in Klaviyo's dataset reach conversion rates as high as 7.69%. These results reflect the strong purchase intent of subscribers who have already engaged with a product page or added items to a cart.
Campaign Monitor reported that over 75% of iPhone users had upgraded to iOS 15, and among those users, roughly 97% had adopted MPP. Combined with Apple Mail's market share, this translated to MPP touching 40-50% of all email opens industry-wide, permanently altering the baseline against which open rates are measured.
Analysis from multiple sources, including Eksido and Mailforge, found that in heavily Apple-skewed subscriber bases, the share of machine-generated opens can reach 75%. As MPP-like prefetching spreads to other platforms, this distortion is trending toward becoming the default condition across email marketing rather than an Apple-specific anomaly.
On February 6, 2025, Brevo changed its default reporting behavior to include Apple MPP opens, joining a broader industry pattern where ESPs inconsistently handle MPP data. EmailTooltester documented the change firsthand, noting it caught many marketers off guard and illustrates how reported open rates can shift dramatically based on ESP settings alone, independent of any real change in subscriber engagement.

Transactional emails, such as order confirmations, invoices, and account alerts, dramatically outperform promotional campaigns in the B2B space. Their relevance and timing are inherently high, which explains why they function as a key driver of overall B2B email engagement.
Belkins' 2025 cold email benchmark study found that email length has a direct impact on both opens and replies. Messages under 200 words consistently outperform longer formats, pointing to a clear preference among B2B recipients for brief, direct outreach that respects their time.
While the median B2B open rate sits in the 36.7% to 42.35% range, the top 25% of programs exceed 50% opens. These results are driven by rigorous audience segmentation, AI-powered personalization, and strong deliverability infrastructure, not higher send volume.
Litmus 2024 data shows four in five email marketers see measurable performance gains when they use personalization, and more than two-thirds specifically credit dynamic content, where different content blocks are served based on subscriber data, as the tactic that moves the needle most.
While the median B2B open rate sits at 36.7% to 42.35% in 2025, top-performing programs that combine rigorous segmentation, AI-powered personalization, and deliverability optimization consistently reach 50%+ opens and double-digit click-through rates. The gap between median and top-quartile senders illustrates how much list quality and targeting strategy determine outcomes.
