Fastmail is the service I've paid for longer than any other, without any pauses, and with the most satisfaction of any subscription.

It's so gratifyingly functional and boring.

I do like that they are up front with how the data is handled and what that can mean for privacy. They are just working within the system but being transparent with it.
