I had a gmail lockout scare recently for my custom domain. And I deeply want to change providers. google is currently both my e-mail provider and my domain registrar. The only thing holding me back is I have a custom domain, I'm not specialized in the web, and it's not super intuitive how to set up my hosting with one company, name registration with another, and e-mail with a third. All for the same custom domain.
