Email Open Rates and Click-Through Rate Benchmarks 2026: Industry Data

The median email open rate across 3.6 million analyzed campaigns is 43.46% in 2026, though the definition of “open” changed materially in 2021 with Apple’s Mail Privacy Protection (MPP) — a critical caveat that applies to every open rate benchmark published since then. For email open rates and click rates benchmarks 2026, the most authoritative sources are ActiveCampaign’s annual benchmarks (based on campaigns sent January–December 2025), Klaviyo’s 2026 e-commerce data, MailerLite’s cross-industry analysis, and Omnisend’s 2026 automation benchmarks. This data roundup presents all major benchmark figures with their source, methodology, and industry-specific breakdowns.

The Apple MPP effect deserves an upfront acknowledgment before citing any open rate figure: since September 2021, Apple Mail automatically pre-fetches email content for privacy protection, triggering open tracking pixels for all emails sent to Apple Mail users — regardless of whether the recipient actually opened the message. Apple Mail commands an estimated 53% of mobile email opens globally. This means raw open rates reported by most platforms are inflated by an estimated 10–20 percentage points compared to pre-MPP baselines. Platforms that have adjusted for MPP show significantly different headline figures than those reporting raw data. This article flags the methodology where known.

Overall Email Benchmarks 2026

The following table presents headline email marketing benchmarks from the four most comprehensive 2026 data sources, covering open rates, click-through rates (CTR), and click-to-open rates (CTOR):

*Open rates marked with asterisk include Apple MPP-inflated data. True engagement open rates are estimated 10–20 percentage points lower. ActiveCampaign CTR figure is higher than industry average due to customer audience mix (primarily SMB/mid-market B2B).

The significant variance in CTR between ActiveCampaign (6.21%) and MailerLite (2.42%) reflects audience composition differences, not platform capability differences. ActiveCampaign’s customer base skews toward B2B and SaaS senders with highly targeted, behavioral-triggered campaigns — a segment that consistently outperforms broadcast-heavy sender profiles on click metrics.

Open Rates and CTR by Industry

According to ActiveCampaign’s 2026 Email Marketing Benchmarks report (based on campaigns sent January 1–December 10, 2025), the following industry-specific benchmarks apply to 2026 planning:

The lowest open rates appear in high-volume, broadcast-heavy industries (e-commerce) where list sizes are large, segmentation is often shallow, and frequency tends toward promotional. The highest open rates appear in high-trust, relationship-driven categories (religion, non-profit) where subscribers have strong personal connections to the sender.

The low CTR for e-commerce (1.07%) despite strong CTOR (3.3%) reflects the high proportion of promotional emails in the category — recipients who do open are reasonably likely to click, but a large percentage of delivered emails are never opened. Behavioral-triggered flows (see below) substantially outperform these broadcast averages in every e-commerce segment.

Performance by Campaign Type

Email campaign type has a stronger effect on performance than industry vertical for most metrics. According to Omnisend’s 2026 Email Marketing Statistics and Klaviyo’s 2026 benchmarks:

Email Flows vs Broadcast Campaigns

The performance gap between automated email flows (behavioral-triggered sequences) and broadcast campaigns is one of the most consistently documented findings in 2026 email marketing benchmarks. According to Klaviyo’s 2026 Email Marketing Benchmarks report:

• Email flows deliver 5.58% click rates vs. 1.69% for broadcast campaigns — a 3.3x improvement
• Email flows deliver 13x higher placed order rates than broadcast campaigns (in e-commerce contexts)
• Welcome series emails average 57% open rates — approximately 18 percentage points above the all-campaign average
• Cart abandonment flows recover an estimated 5–15% of abandoned carts at a 5.2% conversion rate on emails opened

This performance differential is the core quantitative argument for investing in marketing automation over simple email broadcasting.

Send Time and Frequency Data

According to MailerLite’s 2026 Email Marketing Benchmarks analysis and corroborating data from HubSpot:

Best Days to Send

• Tuesday: Highest average open rate (21.8% of senders report this as their best day)
• Thursday: Second highest open rate; highest click-through rate in B2B segments
• Saturday: Lowest volume day but often above-average CTOR for consumer-facing senders

Best Times to Send

• 10:00–11:00 AM local time: Consistently highest open rate across industries
• 1:00–2:00 PM: Second highest, particularly strong for e-commerce and retail
• 6:00–7:00 PM: Highest CTOR for consumer lifestyle and non-profit categories

Optimal Send Frequency

The 2026 data on email frequency confirms that there is no universal optimal frequency — the key variable is list engagement quality rather than absolute count. Omnisend’s 2026 analysis shows:

• Lists receiving 1–2 emails per week average 36.4% open rates
• Lists receiving 3–5 emails per week see open rates drop to 27.2%
• Lists receiving daily emails average 21.8% open rates but generate higher absolute click volume per month

Deliverability Rate Benchmarks

Email deliverability — the percentage of sent emails that reach the recipient’s inbox rather than spam or bouncing — is distinct from open rate and is not inflated by MPP. According to ActiveCampaign’s 2026 benchmarks and industry standards:

• Average inbox placement rate: 84.2% across all senders
• Top-decile senders (best list hygiene, authentication, reputation): 92–96%
• Average spam rate: 0.08% (Gmail’s threshold for bulk senders is 0.10%)
• Hard bounce threshold for maintaining sender reputation: Below 0.5%
• Unsubscribe rate threshold indicating list health problems: Above 0.5% per campaign

Apple MPP: What It Means for Your Open Rate Data

Apple Mail Privacy Protection (MPP), launched September 2021, instructs Mail app servers to pre-fetch email content — including tracking pixels — before the user even opens the email. This means every email sent to an Apple Mail user is recorded as “opened” in most ESP reporting dashboards, regardless of actual engagement.

The practical implications for benchmarking in 2026:

• Any open rate benchmark cited from a platform that has not adjusted for MPP overstates true engagement by an estimated 10–20 percentage points.
• Click-through rate and click-to-open rate (CTOR) are now the primary engagement indicators for email performance evaluation, as they are unaffected by MPP.
• CTOR (clicks as a percentage of opens) is particularly valuable: it normalizes for the inflated denominator created by MPP, giving a clearer picture of how compelling opened emails are to actual readers.
• Conversion rate (email-attributed revenue or lead actions) is the ultimate performance metric and is fully immune to MPP distortion.

According to monday.com’s 2026 email open rate analysis, a “good” open rate in 2026 is context-dependent: 37.93% is considered a good average, with top-performing senders reaching 54.78%. These figures include MPP inflation. Adjusted for MPP, the equivalent “good” threshold would be approximately 20–28% true engagement open rate.
