What are your experiences with Fastmail? Do they encrypt all your emails and in which country are their servers located?
Servers are located at New York Internet (NYI) in New York City, USA. I'm not sure if server location matters to me at this point.
Emails are not encrypted, but all incoming and outgoing connections are.
So I switched from Gmail to Fastmail. I'm loving the service. The web app is pretty snappy and works really well. Even on mobile it is surprisingly responsive.
I find their UI beautiful and quite intuitive (don't read too much into this, as I am someone who really dislikes material design -- one of my grips with Gmail).
Really can't complain. I'd recommend Fastmail to anyone wanting a private mail service.
And I don't feel I'm missing anything.
