Open Rate
The percentage of delivered emails that recipients open.
Why It Matters
Open rate indicates whether your subject lines and sender name are compelling enough to earn attention.
How It Works
ESPs track opens by embedding a tiny invisible pixel in emails; when the image loads, it registers an open. Apple Mail Privacy Protection pre-loads pixels, inflating open rates since 2021.
Real-World Example
An email sent to 5,000 subscribers with 1,250 opens has a 25% open rate.
Common Mistakes
Treating open rate as perfectly accurate post-iOS 15
