First & last name in email alone doesn't guarantee to hit inbox. Huge free email services use social 'signals' as open rates, 'this is spam', 'this is not spam' as well as IP reputation i mentioned earlier to determinate if email hit inbox.

So, there is obviously a difference in those metrics between simple notification 'your account have been hacked. change password' and 'hey, we haven't seen you for ages'. As email system notice high user involvement it will never ever block such emails. Actually, i think it will increase IP reputation.
