Unsubscribe Rate
Unsubscribe rate is the share of people who opted out after getting your email.
Every marketing email needs an easy way to unsubscribe. Unsubscribe rate is how many people used it, divided by how many got the email.
A small amount is normal and healthy. A sudden jump is a warning that your emails are going to the wrong people or coming too often.
