Unsubscribe Rate
The percentage of recipients who opt out of an email list.
Unsubscribe rate measures how many recipients choose to stop receiving emails from a campaign. High unsubscribe rates can indicate irrelevant content, excessive frequency, or poor targeting. Analyzing unsubscribe feedback helps marketers refine their strategy and retain more subscribers. Providing an easy-to-use and transparent unsubscribe process is also required by law.
