Click-to-Open Rate Industry Average: 2026 Benchmarks

Click-to-Open Rate Industry Averages: 2026 Benchmarks That Actually Help

You pulled up last week's newsletter stats and saw a 4% CTOR. Opens look fine - better than fine, actually. But clicks? Flat. Across r/Emailmarketing, the same story keeps repeating: opens climbing, engagement stalling. Your content didn't get worse. The click-to-open rate industry average you're benchmarking against is lying to you.

The median CTOR across all sectors was 6.81% in 2025, based on 3.6M campaigns analyzed by MailerLite. A "good" CTOR falls between 6-17% depending on industry. If yours looks suspiciously low, Apple Mail Privacy Protection is almost certainly inflating your opens and dragging the ratio down.

What Is Click-to-Open Rate?

CTOR measures how compelling your email content is once someone actually opens it:

CTOR = (Unique Clicks / Unique Opens) x 100

500 unique opens and 50 unique clicks = 10% CTOR. The key distinction from CTR: click-through rate divides clicks by total emails delivered, reflecting both subject line and content quality together. CTOR isolates content quality by only counting people who opened. That's a narrower, more useful question - and the one most teams should be asking when they're trying to figure out why clicks aren't keeping pace with opens.

CTOR vs. CTR vs. Open Rate

Post-Apple MPP, Salesforce's benchmark guidance pushes marketers toward CTR and CTOR as more reliable signals. Opens are increasingly a vanity metric. Clicks aren't.

2026 CTOR Benchmarks by Industry

We've consolidated data from three major benchmark reports. MailerLite reports medians, which resist outlier distortion, while GetResponse reports means. For industries without dedicated source data, we've estimated ranges based on the 6.81% overall median and typical vertical variance - MailerLite's full report covers 46 industries if you need a deeper cut.

Year-over-year, the trend is positive - overall CTOR jumped from 5.63% in 2024 to 6.81% in 2025. Gmail's one-click unsubscribe changes are purging unengaged subscribers, which lifts engagement rates for everyone who stays.

Here's the thing: track your own 90-day CTOR baseline before obsessing over industry numbers. Your internal trend matters more than any external benchmark. A CTOR climbing from 5% to 7% tells you more than knowing the cross-industry median is 6.81%.

One distinction most benchmark articles miss entirely. Automated flows consistently crush campaign blasts. Klaviyo's 2026 benchmarks show automated flows drive around 3x the click rate of one-off campaigns on average. If you're only measuring CTOR on campaigns, you're ignoring where the revenue actually lives.

CTOR by Region

Geography matters more than most marketers realize, because inbox client mix and privacy features vary wildly by country, and that skews what counts as an "open."

These gaps are exactly why a single "industry average" CTOR can mislead. If one region or one segment of your list has more privacy-driven opens, your ratio looks artificially low even when click intent hasn't changed at all.

Why Your CTOR Is Probably Wrong

Apple Mail Privacy Protection accounts for roughly 49% of all email opens as of early 2025. MPP pre-fetches every email and marks it as "opened" regardless of whether the recipient looked at it, inflating open rates by 15-20+ percentage points and dragging CTOR down.

Let's break this down with real numbers. Pre-MPP, your campaign gets 500 real opens and 50 clicks - a 10% CTOR. Post-MPP, the same campaign shows 900 "opens" because 400 Apple Mail users got phantom opens. Same 50 clicks. Your CTOR drops to 5.6%. Identical content, nearly halved metric.

It gets worse. Gmail and Outlook security scanners now "click" links to check for malware - AI-driven security bots peaked at 3+ million link clicks per day in early 2025. We've seen teams spend entire quarters A/B testing body copy when the real problem was measurement corruption. CTOR isn't dead, but it's much harder to interpret in Apple-heavy segments because the denominator is broken.

How to Improve Your CTOR

Even with measurement noise, CTOR remains the best proxy for email content quality. Here's what actually moves the needle.

Segment by engagement. Stop sending to your full list. Build segments of 30/60/90-day clickers and high-intent subscribers so your results aren't dominated by phantom opens. This single change will do more for your CTOR accuracy than any copy tweak.

One CTA per email. Decision fatigue kills clicks. Every additional link competes with your primary action. We've tested this across dozens of campaigns and the data is consistent - fewer choices, more clicks.

A/B test the body, not just the subject line. CTOR isolates content quality, so test layouts, copy length, CTA placement, and offer framing. That's where CTOR-specific gains live.

Start with clean data. Bad email addresses tank your sender reputation, reduce inbox placement, and corrupt your CTOR denominator from both directions. Prospeo's 5-step email verification catches invalid addresses, spam traps, and catch-all domains before they hit your ESP. One B2B team dropped bounce rates from 35% to under 4%, which didn't just improve deliverability - it made every downstream metric, including CTOR, trustworthy again. If you want the deeper mechanics, start with an email deliverability audit and then track your email bounce rate by source.

Skip list cleaning if you're running a small hobby newsletter with under 500 subscribers. For everyone else, especially B2B senders, dirty data is the silent killer behind metrics that don't make sense.

FAQ

What is a good click-to-open rate?

Between 6-17% depending on your industry. Above 10% is strong for most lists, while B2B newsletters typically land in the 5-8% range. If you're consistently below 4%, investigate content quality and list hygiene before blaming the metric itself.

Is CTOR more accurate than open rate?

CTOR measures content engagement among openers, so it's less affected by deliverability issues. But Apple MPP inflates the "opens" denominator, dragging CTOR down artificially. Pair CTOR with raw CTR for a fuller picture of campaign performance.

How does CTOR differ between automated flows and campaigns?

Automated flows - welcome sequences, abandoned carts, post-purchase emails - consistently produce 2-3x the click rate of one-off campaign blasts. They also drive disproportionate revenue. If you're only benchmarking campaign CTOR, you're missing the highest-performing part of your email program.

How can I get accurate CTOR with Apple MPP inflating opens?

Segment your list by email client and exclude Apple Mail openers from CTOR calculations, or switch to CTR as your primary engagement metric. Cleaning your list with a verification tool also helps - removing invalid addresses tightens both your open and click denominators so the ratio reflects real human behavior.
