What is Unsubscribe Rate?

Quick Answer

The percentage of recipients who opt out of your mailing list after receiving an email.

Unsubscribe rate = (unsubscribes / delivered emails) × 100. Average is 0.1-0.5%. Rates above 0.5% signal content relevance issues. A clear, one-click unsubscribe link is legally required (CAN-SPAM, GDPR). MisarMail uses List-Unsubscribe headers and one-click unsubscribe for maximum compliance.
