Yet another warning about entrusting Gmail (or anyone else) with your email

Actually, a question that’s right on-topic for this thread (sorry for the double-reply):

I’m playing with the idea of a Fastmail subscription as I explore the different service alternatives (linking that thread again, for your convenience: iCloud Mail, Fastmail, Gmail: what are the differences? The Email Service Feature Comparison Table).

Do folks think it’s better to:

  • Create an account (e.g., ryanjamurphy\at\fastmail.com) with the service, then add my own domain to that account; or
  • Create an account with Fastmail with my domain?

I am leaning towards the former, but I don’t know if it matters…
