Open rates vary widely by industry, and Apple's privacy changes have made the metric noisier and less reliable than it used to be.
Subject line and sender reputation drive most of the variance in opens — list quality underpins both.
Clicks and revenue per email are more trustworthy success metrics than opens in a post-privacy world.
A smaller, engaged list consistently out-opens and out-earns a large, stale one.
Read open-rate benchmarks with a grain of salt
Open rates are the most quoted email metric and, increasingly, the least reliable. Apple's Mail Privacy Protection pre-loads images for many users, which inflates and distorts open reporting — a chunk of your 'opens' are machines, not people. The industry benchmark ranges are still useful for orientation, but treat them as approximate. If your opens look dramatically below the range for your sector, that is worth investigating; small differences are noise.
The healthier way to use these numbers is comparative and directional: how do your opens trend over time, and how do they move when you change subject lines or clean your list. Obsessing over hitting a specific industry open-rate figure, given how compromised the metric now is, chases a number that no longer means what it used to.
What actually drives opens
To the extent opens still matter, two things dominate them: the subject line and your sender reputation. The subject line is the single biggest controllable factor — it is the entire pitch for whether someone opens at all, and small improvements compound across every send. Sender reputation, built on consistent engagement and clean sending practices, determines whether you even reach the inbox to be opened in the first place.
Underpinning both is list quality. A list full of disengaged contacts drags down engagement signals, hurts deliverability, and depresses opens for everyone. Subject-line testing only pays off when the mail is actually reaching engaged people, which is why list hygiene is the foundation beneath every open-rate tactic.
Measure clicks and revenue, not just opens
Because opens are now unreliable, the metrics worth steering by are the ones tied to action: click-through rate and, above all, revenue per email or per recipient. Clicks indicate genuine interest, and revenue tells you whether the email did its job. An email with a great reported open rate but few clicks and little revenue has a problem the open number will never reveal.
Shift your reporting and your optimisation toward these downstream metrics. Use opens as a rough directional signal and a list-health indicator, but judge campaigns on what they actually produce. The senders adapting best to the privacy era stopped treating opens as the scoreboard and started treating clicks and revenue as the truth.
Common mistakes that quietly kill results
These come straight from audits we run every week. If any of them stings, you’re in good company — and the fix is usually faster than you think.
Flows set up once and never audited. Your abandoned-cart flow from 2024 references products you discontinued. Quarterly flow audits — links, offers, timing, branching — take an hour and routinely recover 10-20% lost revenue.
No plain-text-feeling sends. Heavily designed emails scream 'marketing.' A short, plain note from the founder converts shockingly well for winbacks and high-AOV nudges. Test one this month.
Discount-only retention. If every email is a coupon, you've taught customers to wait for one. Mix in usage content, restock alerts, reviews, and founder notes — the brands with the best LTV send value 60% of the time.
Ignoring deliverability until it breaks. Sunset unengaged profiles after 120-180 days. A smaller list that opens beats a big list in spam — and once Gmail flags you, the climb back takes months.
From the trenches
A jewelry brand sent SMS like email — 5× a month, full paragraphs. Unsubs at 4.2% per send. We cut to drops-and-restocks only, under 160 characters. Unsubs fell to 0.6%, and the next restock text did $23K in 4 hours.

Frequently asked questions
What is a good email open rate?
It varies by industry, with many sectors landing in the 25 to 45 percent range. But Apple's privacy changes have inflated and distorted opens, so treat benchmarks as approximate and lean on clicks and revenue for a truer read.
Why are my email open rates inaccurate?
Apple's Mail Privacy Protection pre-loads images for many users, registering opens that are not real human opens. This inflates and distorts the metric, which is why clicks and revenue are now more reliable.
How do I improve email open rates?
Focus on subject lines, which drive most of the variance, and protect sender reputation through clean sending and list hygiene. A smaller, engaged list reliably out-opens a large, stale one.
