List-unsubscribe

List-unsubscribe is an optional process included in the email header, enabling subscribers to opt out of an email list without clicking on an unsubscribe link. At Mailgun, we always recommend providing subscribers an option to stop receiving emails, so they don’t mark emails as spam. If they do, it can tank a domain’s reputation and email deliverability.

All email clients handle list-unsubscribe requests differently. For instance, Gmail includes an option to “Unsubscribe from this sender” when a user hovers over a sender’s email address. It also includes a link besides the email sender’s address, which is visible when the receiver opens the sender’s email.
