Unsubscribe rate

Unsubscribe rate is the percentage of recipients who opt out of your emails.

In outbound, unsubscribes are not the enemy.

They are often a protective mechanism.

If someone does not want your emails, you want them to unsubscribe instead of marking you as spam.

Why unsubscribe rate matters

• It is a signal about targeting and messaging fit.
• It reduces spam complaints when honored immediately.
• It keeps future sends cleaner.

A low unsubscribe rate is not always good if it is paired with a high spam complaint rate.

What is a “good” unsubscribe rate?

It depends on your ICP, list source, and volume.

What matters most is trend and correlation:

• If unsubscribe rate rises sharply, your targeting or message angle is off.
• If unsubscribe rate is low but spam complaints are rising, your opt-out UX or suppression logic may be broken.

Operational rule

• Honor unsubscribes immediately.
• Keep a global suppression list.
• Treat every unsubscribe as feedback on fit.
