Big +1 on fastmail.

However, the big upside is that I have my own domain now, so if I need to migrate to something else (be it self-hosted or another provider) I can easily do so without losing all my contacts.

Exactly, I've got a filter in Fastmail that collects mail that's still delivered to my old @gmail.com account (I still have forwarding there).

When I get bored, I wade through it and either change the address to my current one (with my own domain) or unsubscribe.
