We have invested in a new domain for 33mail users to play with namely 33m.co. You can now create your 33mail addresses @<username>.33m.co which will save you from typing 4 characters every time you use a 33mail address (unless, that is, you use the 33mail bookmarklet or the 33mail chrome extension). That’s a massive 40% saving for your fingertips, and will surely add to your keyboards longevity.

Cue the landrush for one and 2 character usernames, I assure you there are some still available.
