Hello @DawnD1 ,
The unsubscription process is purposely set up so contacts can efficiently and simply unsubscribe from receiving all mailings. This is done to ensure that we, and those who use our system, are fully compliant with domestic and international anti-spam laws.
With that said, you can give potential unsubscribers the chance to instead simply opt out of certain lists. To grant this option, you'll want to make sure you set up the Update Profile form to display list options for contacts to select. These list options will also display on the unsubscription confirmation page a contact sees, so they're given the option to opt out of specific lists if so desired, rather than wholly unsubscribe from you.
