Hi, Regarding your request to add an unsubscribe link to Quick Campaign/Campaign is supported. You can add an unsubscribe link by clicking on the unsubscribe button while creating an email campaign in Quick Campaign.
If you're using a Campaign instead of Quick Campaign, you'll need to create the Campaign, then click "Distribute Campaign" and add an "Unsubscribe" link to the design email, just like Quick Campaign.
I hope my answer is helpful to you! If you have any other questions, please feel free to contact me. Best Regards, Rudy Zhang
