Lesser known FastMail features

I just discovered a bunch of other things that FastMail can do (besides just hosting my email):
  • DNS server
  • File storage
  • Website host
  • Website redirects
  • Automatic photo galleries from files
  • SMS via email (haven't figured this one out yet)
  • Note-taking (notes sync via IMAP)
  • 2FA with U2F and YubiKey OTP support
