Benchmarks are useful for spotting obvious problems, but they are not the final scorecard. A campaign with average opens and strong sales can be healthier than one with high opens and weak revenue.
Open Rate Is Context
Privacy features make opens less reliable than they used to be. Use opens to spot big deliverability or subject-line issues, then judge quality with clicks, replies, and conversions.
Click Rate Shows Message Fit
If opens are healthy and clicks are weak, the subject line may be attracting attention that the email does not satisfy.
Unsubscribes Show Fatigue
A rising unsubscribe rate can point to poor list source, too much frequency, weak relevance, or a mismatch between signup promise and email content.
