How? On your inactive email account? My experience has shown that they're not great about deletion notifications. They changed how deleted items work in Drive, but never notified me outside of drive (work or personal, my memory backed up by a negative gmail search). Which was fine in this instance, but it doesn't set a great trend. It's unfortunate, too, because their security group is nicely pedantic in notifying you about things.
