Didn't proton's compliance canary die not too long ago?

Sure, but let’s also be realistic that any service large / secure enough to trust your email to will also be large enough to have drawn the attention of entities that can force them to do things against their will.

Thanks will check this out. Hand't heard of them before.

Slightly more expensive than Fastmail but seems like better security / privacy considerations.

That said, the space per inbox seems far more limited.

Seems we have some interesting options here!
