What Is a Good Email Open Rate? Benchmarks and What to Track

So, what is a good email open rate? In the large benchmark reports we checked, a typical campaign lands somewhere between about 25% and 30%, and the spread by industry runs from the high teens to the low 50s. The honest answer has a second half, though. Since Apple added Mail Privacy Protection, a big share of opens are counted by a machine, not a reader. So treat open rate as a rough health signal, and judge your email by clicks, replies and sales.

How email open rate is calculated

Open rate is the share of delivered emails that registered an open. The usual formula is unique opens divided by delivered emails, times 100. Delivered means sent minus bounces, so addresses that never received the message do not drag the number down. Unique means each person counts once, even if they open the email five times. Check which version your platform reports, because a few tools also show total opens, and the two numbers can look very different.

A worked illustration

Here is an invented example with round numbers. You send a newsletter to a list of 2,000 people. Forty addresses bounce, so 1,960 emails are delivered. Your report shows 588 unique opens. The open rate is 588 divided by 1,960, which is 30%. The same report shows 49 people clicked a link. That is a click-through rate of 49 divided by 1,960, or 2.5%. Measured against opens instead, 49 divided by 588 gives a click-to-open rate of about 8.3%.

Run those three numbers on every send. Each one points at a different stage. Open rate reflects the sender name, the subject line and inbox placement. Click-through rate reflects the whole email. Click-to-open rate isolates the content: of the people who opened, how many found something worth clicking? When one of them drops while the others hold, you know where to look.

Why open rates got less reliable after Apple Mail Privacy Protection

Opens are tracked with a tiny invisible image. When the image loads, the platform logs an open. Apple's Mail Privacy Protection changed what that load means. In Apple's own words, with Protect Mail Activity selected, the reader's IP address is hidden from senders and remote content is privately downloaded in the background when a message arrives, instead of when it is viewed ^[1]. The pixel fires on delivery. Nobody has to read anything.

Stretch the illustration from above. Suppose 500 of your 1,960 recipients read mail in Apple Mail with that setting on. Those 500 can log as opens the moment the email lands, whether anyone looks or not. That alone is about 25.5% of delivered email. Your 30% open rate might rest on fewer than a hundred other opens plus a block of automatic loads. The report cannot tell you which is which.

That has knock-on effects. A subject-line test judged on opens can crown the wrong winner. A send to non-openers resend skips people who never saw the first email. Re-engagement rules that remove anyone who has not opened in six months may keep inactive Apple users forever. None of this makes open rate useless. It makes it a trend line for your own list, not a score to compare with anyone else.

What is a good email open rate? The industry averages

Benchmarks only mean something when you know whose emails were counted. Two readable reports show the range. Omnisend, which serves online stores, reports an average open rate of 30.22% across industries in its 2025 dataset of campaign emails, and it warns that Apple's protection can make some emails appear opened before anyone reads them ^[2]. The same report shows a wide spread by industry, from the low 50s for wedding brands down to the high teens for its lowest category.

Benchmark Email, from data on its own users, puts the average open rate at 25.54% and the average click rate at 1.45% ^[3]. Both figures are averages of each vendor's customers, not of the whole market. A store sending daily promotions, a nonprofit sending a monthly update and a consultant writing to 300 clients will never share one target.

The comparison that matters most is your own last ten sends. Industry averages tell you whether something is badly off. Your trend tells you whether a change you made worked.

Email marketing metrics that matter more than opens

Clicks are the first honest signal. A click needs a human finger, so it survives privacy features that inflate opens. Omnisend makes the same point, calling click-through rate a clearer engagement signal since Apple's change. In its store-heavy data, the overall click-through rate sits under 1%, while Benchmark Email's broader user base shows 1.45%. That gap is normal. Promotional store mail gets sent often and clicked less per send.

Track these alongside open rate:

1. Click-through rate. Unique clicks divided by delivered. Your best day-to-day measure of interest.
2. Click-to-open rate. Clicks divided by opens. Shows whether the content earned the click, though inflated opens pull it down.
3. Conversion rate. The share of recipients who bought, booked or signed up. Needs tracking on your site.
4. Unsubscribe rate. Unsubscribes divided by delivered. A spike after one send is a message about that send.
5. Spam complaints and bounces. Small numbers with large consequences for inbox placement.
6. Replies. For a small business or a newsletter, a reply is worth more than any rate.

Stores often go one step further and judge each automated sequence by revenue per recipient. In Klaviyo, for example, the number to watch is revenue per recipient by flow rather than opens, because privacy-protecting mail clients make opens unreliable. Non-store senders can borrow the idea: pick the one action your email exists to cause, and count that.

How to get more emails opened and read

Opens follow trust first and copy second. A recognizable sender who reliably sends useful email gets opened even with an average subject line. Work in this order:

1. Fix the sender name. Use a name people recognize, a person or the business, and keep it the same every time.
2. Land in the inbox. Authenticate your domain and remove addresses that bounce. Mail in spam has a near-zero open rate.
3. Write for one reader. Say what is inside in plain words. Promising more than the email delivers costs you the next open.
4. Use the preview text. It is the second line in most inboxes. Leave it blank and the inbox fills it with whatever comes first.
5. Send to the people who care. Split the list by interest or recent activity, and cut back mail to people who have stopped clicking. Our guide to email segmentation shows how the tools handle it.
6. Test one thing at a time. Two subject lines, same send, same audience. Judge the winner on clicks where the tool allows it, since opens are partly automatic.
7. Pick a steady rhythm. Subscribers who know when you arrive watch for you.

The subject line deserves its own work. Length, wording and testing it without a paid tool are covered in our step-by-step guide to writing email subject lines. Short rule here: make it specific, make it true, and match the inside.

Tools that test and time it for you

You can measure opens and clicks in almost any email platform. What differs is help with the levers above: testing, timing and sending to the right people. Mailchimp starts A/B testing on Essentials and adds Send Time Optimization on Standard and Premium. Brevo puts A/B tests and AI send-time optimization on Standard, with AI subject lines from Starter. Kit allows A/B tests on broadcasts even on Free. The segmentation guide above compares how each one splits a list.

The bottom line

A good email open rate is the one that holds steady or rises on your own list. The reports we checked put typical campaigns between about 25% and 30%, but Apple's privacy feature inflates that number, so it cannot carry decisions alone. Calculate it the same way every time, watch clicks and replies next to it, and spend your effort on the sender name, inbox placement and email people actually wanted.
