Hello @CETTL
A deceased contact isn't going to be a viable contact, even if they were previously very engaged. If the contact's email address ends up somehow being in use again, it wouldn't be the same person obviously, and wouldn't necessarily meet the permissions requirements or potentially your own criteria for wanting them to be a contact.
You're of course welcome to keep the contact's address in your account, but since they won't be viable to send to, I'd advise at least unsubscribing them. That way you don't have to delete, or even if you do and they get re-uploaded / synced from elsewhere, they won't count as an active contact.
