A newsletter unsubscribe form is a special form of the web forms. After the form submission, the system marks the corresponding entry in the pool as deleted. However, it should be as easy as possible for the newsletter recipient to unsubscribe via the 1-click unsubscription.
For security reasons, we recommend not to integrate this form directly into the website, but to send it as an e-mail, which the system sends to the person to be unsubscribed as a confirmation e-mail of an upstream form. This prevents misuse of this function.
Create a form, see: Create Forms.
In the deregistration form within the Configuration tab, activate deregistration as the entry procedure and select Profile ID as the uniqueness criterion.
Select the profile ID during the unsubscribe procedure to uniquely identify the profile.
Link the unsubscribe form in an e-mail that you send to the profile directly or via an upstream form in order to uniquely assign the profile.
Link the unsubscription form directly in an e-mail sent directly to the profile.
