It's hard to avoi nd this chicken and egg situation. I use fastmail and they allow you "alias" addresses. So even though my primary email is on my custom dimain e.g. myname@mydomain.com, Fastmail also gives me an alsia of myname@fastmail.com. That's the email I used to log in (to AWS) and manage my MX records. If either Fastmail or AWS were to go rogue/broke, I like to think I would eventually be able to restore access to my domain even without email? Hope never to find out.
