Yo, wanna move away from gmail as the anchor for my online identities that I can't selfhost (e.g. email for Domain registrar) - anyone got any recommendations for european providers worth checking out?

Ok, recommendations so far: Mailbox, Proton, Tuta, Posteo.

Excluding Proton for "on my personal shitlist" reasons.

Will ignore Tuta free tier as I don't want to be dependent on a fundamentally unsustainable business model.

Don't need bells & whistles so always going with the lowest paid tier. This unfortunately kicks out Tuta as they are 3x as expensive.

Posteo is kinda ... eh for me as it requires pre-payment, limited to 12mo - I know myself, at some point I will forget. So... Mailbox I guess?

Oh, neat, they don't even filter out my own mailserver!
I mean... ok, sure, Linux users WILL figure it out but... 
Ok, lack of Phishing-resistant MFA is a problem... (TOTP only)
Ok, looks like Posteo also doesn't support U2F/WebAuthn. Tuta does though! Might need to reconsider...
@nyanbinary I will eventually get and then regret getting a "Webauthn4Life" tattoo. Thanks for doing the research!
@SporkSan ...I have been thinking about which tattoos to get and you are giving me stupid ideas 
@nyanbinary fido2 adjacent is on the list for a future tattoo, I need to get a #battletech one first. They really are addictive.
