Some email clients support reading a <code>List-Unsubscribe</code> header within emails which enables them to display a prominent option to allow a user to unsubscribe from mailing lists. The mechanism for notifying you about a user's request to unsubscribe is an email sent to the address specified here.<br />
<br />
<b>Note:</b> Unless you enable "Automated unsubscribe email handler" below, it will be entirely your responsibility to manually check and process such emails, unless you are using a third party service that will do it for you. A value is required here if you enable the automated option.
