Since I use Google Apps for my email, I could easily move my mail to another service without telling people my new address but Fastmail doesn't seem to support using your own domain. Do you know any service like Fastmail but with domain support? Edit: The "family" package offers this: https://www.fastmail.fm/signup/family.html https://www.fastmail.fm/signup/family.html Edit Again: I should have poked around more, it's included in the personal package too.
