This is probably worth doing, but one should be aware that a typical e-mail address does not contain enough entropy to not be guessable offline.
Perhaps someone should deliberately leek a bogus database that contains the bcrypt hash of [email protected] and see if that account starts receiving spam ... probably it won't.
There is (almost certainly) no associated e-mail account, but the following is the SHA-256 hash of firstname.lastname.threedigits, something like "davey.jones.490". I'm half-expecting someone to reply with the solution, though I think there are about 36 bits of entropy in my choice:
