Editing Email Deliverability Reports (section)

== Does the List-Unsubscribe Header Increase My Unsubscribe Rate? ==

While you may receive a few more unsubscribe requests as a result of the native unsubscribe option, it’s best to remember that these unsubscribe requests come from people who no longer wish to receive your content and who may have already been disengaged with your emails.

Having a native unsubscribe option also means there is less chance that your emails will sit in an inbox unopened for long periods or be deleted without ever being opened—both of which can get your future emails sent to the Spam folder and harm your deliverability.
