> The single team that has navigated the insanity of the email space well as a small company is Fastmail. They are brilliant, ethical, and pragmatic.
I'm curious to know if you have also examined Posteo, Mailbox, Tutanota and ProtonMail in this respect. At least the first two of those seem to be handling things quite well while charging a fraction of what Fastmail charges (per mailbox). Posteo has many other things going for it on the social responsibility, privacy and ethical angles. I haven't seen another email provider match that.
