Can't explain why you didn't get an email when your flight cancelled. It's all software based, not as though somebody at DL sits there tapping out individual emails. DL clearly had your email and had that associated with your flight and clearly sent out at least two emails: the delay and the cancellation. It's unlikely that you were deliberately left off the second email.
