I’ve been a Fastmail user for years, having left Gmail. It works great and have nothing be but praise for them. I use my own domain with them so if I decide to leave it’s not an issue worrying about updating people with my new email.

My mailbox.org username is literally three random short Engish dict words concatnated by underscores (e.g jet_sit_gill@mailbox.org) just to ensure I'd never share that email with anyone. I only use my domain's email addresses. This way there's ZERO lock, zero fear of them giving my email to someone else and staying with the domain provider for a day longer than I have to.
For email addresses on others' domains here
- icloud.com came with the devices (I honestly have not thought about what happens to these if I have zero Apple device at one point in future :D)
- tutanota(barely ever used; just to support them I paid until they removed the 12/year plan)
- protonmail, and sdf.org (ARPA)
All of these at least let me hold on to the email address even with little resources when I stop paying or have an unpaid a/c. So little risk of email goign to someone else. And I never use these for anything important anyway.
For temp emails - duck.com, HideMyEmail (stopped using this one for new accounts though).
