Deleted versus Unsubscribed
Below are the differences between the two options...
Deleted
When a subscriber's status is changed to deleted:
They will no longer receive any emails sent to the list
They will not count toward your subscriber total for billing purposes
It does not add them to the suppression list (if the address is accidentally re-imported, the subscriber status changes back to active)
Their subscriber activity for campaign reports is preserved.
Unsubscribed
When a subscriber's status is changed to unsubscribed:
They will no longer receive any emails sent to the list
They will also be unsubscribed from any other lists that they are subscribed to, except for lists where the unsubscribe setting has been changed
They will not count toward your subscriber total for billing purposes
They will be added to the suppression list
Their subscriber activity for campaign reports is preserved.
TIP
A common approach is to use "unsubscribed" if someone has asked to be removed, and "deleted" if you choose to remove them for any reason. That way you can easily tell the difference later on.
