I don't use my Google account for anything important. The only reason I have one is to use the Play store. I don't browse whilst signed in and receive no email whatsoever. I do this because Google can ban you on a whim, so nothing important is ever stored on my account. If you still have access to your domain, then transfer it to a suitable registrar and go elsewhere.
