Unsubscribe rate measures how often recipients opt out after receiving emails. Learn what unsubscribe rate indicates and how to reduce unwanted churn.
Unsubscribe rate is the percentage of recipients who opt out of your mailing after receiving an email. It’s a normal metric for any list, but unusually high unsubscribes can signal misaligned expectations or irrelevant content.
Unsubscribes are often healthier than spam complaints because they provide a clean exit path. A rising unsubscribe rate may indicate you’re emailing too frequently, targeting the wrong audience segment, or using subject lines that don’t match the content.
To improve, set clear expectations at signup, segment your list, and provide preference options such as frequency controls. Focus on value and relevance so subscribers feel your emails are worth keeping.
