Why are open rates unreliable?
Open tracking works through a tiny invisible image. When it loads, the email counts as opened. Apple's Mail Privacy Protection downloads remote content in the background when an email arrives, whether or not the person opens it. Email services can't always tell the difference, so open rates look higher than reality.
What should you measure instead?
| Metric | What it tells you |
|---|---|
| Click rate | Did the email make people take action? |
| Replies | Do people feel a real connection? |
| Unsubscribe rate | Are you sending the wrong things or too often? |
| Sales or bookings | Is email doing its job for the business? |
| Open rate trend | Still useful as a rough trend within your own list |
What if your numbers are falling?
- Check deliverability. Are emails landing in spam? Follow Gmail's sender guidelines.
- Check relevance. Did your topics drift from why people signed up?
- Clean your list of long-inactive addresses.
- Improve subject lines (examples).
Example
Worked example: reading a month of results
Say you send four weekly emails to a list of 1,000 people. Your email service reports:
| "Opens" | Clicks | Replies | Unsubscribes | |
|---|---|---|---|---|
| Week 1 tip | 52% | 41 | 3 | 2 |
| Week 2 story | 55% | 18 | 9 | 1 |
| Week 3 offer | 50% | 27 | 1 | 6 |
| Week 4 tip | 54% | 46 | 4 | 2 |
The open column barely moves, so it tells you almost nothing. The other columns tell a story: practical tips get the most clicks, the personal story gets the most replies, and the offer email cost a few unsubscribes while still drawing clicks. That's normal. Next month you'd keep the tip-and-story mix and make the offer email more helpful.
How to set up your own baseline
- Pick a fixed window. Look at the last eight to twelve regular emails, not your welcome sequence (welcome emails always do better).
- Record clicks per 100 subscribers sent, not just click rate, so list growth doesn't hide changes.
- Note the email type (tip, story, offer, video) next to each result.
- Review monthly. One bad week is noise; three falling weeks is a signal.
Watch out
Common mistakes with open rates
- Comparing yourself to published "averages." They mix industries, list sizes and privacy settings. Your own trend is the only fair comparison.
- Rewarding clickbait subject lines. A tricky subject line can lift opens and hurt trust. If clicks and replies don't rise too, it didn't work.
- Using opens to remove "inactive" people. Because of privacy preloading, some real readers never register opens, and some non-readers always do. Use clicks over a long period (90 days or more) before you call someone inactive, and send a "still want these?" email first.
- Testing subject lines on opens alone. If your email service lets you, judge tests by clicks.
A quick health checklist
- Clicks are steady or rising over three months.
- People reply to you at least occasionally.
- Unsubscribes spike only after offers, and settle again.
- Your emails land in the main inbox when you test with your own Gmail and Outlook addresses.
Dave’s take
A principle I keep coming back to
"More important than the number of views is the number of engaged viewers." (Dave)
The same is true of email: a reader who clicks and replies beats an "open" that may not be real.
AI shortcut
How can AI speed this up?
AI tools and plans checked October 18, 2026. They change often, so confirm on each tool's own page. No affiliate links.
- Analyze exports. Export your campaign stats and ask ChatGPT or Claude to chart click rate and unsubscribes over time, so you're not relying on opens.
Tools mentioned:
- ChatGPT: free plan, Go ($8 a month in the US) and Plus ($20 a month).
- Claude: free plan, Pro at $20 a month.
AI is great for first drafts. Always edit the result so it sounds like you and is accurate for your business.
Key takeaways
- Open rates are now unreliable because Apple Mail preloads emails.
- Compare your own emails over time instead of chasing an industry number.
- Clicks and replies are better signs of real engagement.
- A falling trend matters more than any single number.
Frequently asked questions
Why did my open rate suddenly jump?
Often because more of your subscribers use Apple Mail with Mail Privacy Protection, which downloads email content in the background whether or not the person opens it. Those preloads can be counted as opens.
