Create Suppression Lists and Remove Contacts

Adding an email address to a suppression list ensures that the recipient will not receive any future emails from the sender, even if they are subscribed to the email list or campaign. This can be useful in cases where the recipient has requested to be removed from the email list or if they have reported the emails as spam or unwanted.
