I was using Proton Mail for a while with a custom domain, which was great as a single user with a single domain. Phenomenal email service and the other apps they offer are cool too.

I ended up switching to Migadu however, as nowadays I need to have multiple domains, and multiple people might need to have accounts on some of them.

- Pros of your own domain: migrating to a new provider is really easy (don’t need to change your email address everywhere), your email provider can’t kick you out and make you lose everything

- Cons of your own domain: if you forget to renew it, you lose your email, but it’s pretty hard to forget to renew it IMO
