It's super-easy to overlook or "dial in" your transactional messaging. Twitter does it smarter with their "password reset" email message:

"Can't remember your password, huh? It happens to the best of us... login and change it to something you'll remember."

The copy is straightforward, cute, "human." Very Twitter.
