Your open rate is higher
than you think
Your open rate is 22%. Industry average is 27%. You’ve tried new subject lines, different send times, A/B tests. Nothing moves the needle. Because the problem isn’t your content. It’s your denominator — the total number of emails your open rate is calculated against.
What you’ll learn
- Why your denominator — not your content — is the problem
- The math: how 22% becomes 31% when you remove dead addresses
- How Apple Mail Privacy Protection compounds the distortion
- The 3-step fix to see your real content performance
The denominator problem — visually
29% of your denominator can’t engage. Catch-all addresses (domains that accept all email, even fake) and role-based addresses (shared inboxes like info@) are counted as “delivered” but produce near-zero opens. Every one is a zero dragging down your rate.
The math: 22% becomes 31%

Real open rate31%
You’ve been optimizing subject lines for a 22% problem. Your real content performance on actual human inboxes is 31%. The 9-point gap isn’t your content. It’s your list composition. These numbers are illustrative — your specific gap depends on your list composition, but the pattern holds.

Apple MPP makes it worse
Apple Mail Privacy Protection (introduced in iOS 15) automatically loads tracking images for Apple Mail users, making it look like they opened your email even when they didn’t. You’re working with two distortions at once: fake opens inflating some numbers, and dead addresses deflating others. The only fix is measuring on a clean segment.

Separate safe vs risky

Send to safe only

That's your real rate
Optimize against this
If your real rate is already 31%, you don’t need new subject lines. You need list cleaning to stop paying for dead contacts →
