Unsubscribes, Complaints and Bounces are Account-wide

On our system when you get an unsubscribe, a complaint or a bounce it apply it to all lists on your account.  These are conditions that contribute to a lack of list quality and in order to protect your account and our system we do this to prevent "teasing the dog", so to speak. That way if you are doing marketing across several subscriber lists, we won't keep trying to send to someone who has unsubscribed, bounced or complained.

This is not changeable.
