Email Blaster handles all of this for you – so you don’t need to delete people who have opted to unsubscribe. 

Every email you send out will have a small unsubscribe link placed at the bottom, so you don’t need to add your own. If people click on this link, they are tagged as unsubscribed inside the software and automatically excluded from your future sends.

You can view any unsubscribes either in the lists section or in your campaign analytics.
