> In the end I went with Runbox, will see how they perform but I’m happy so far.

I tried Runbox back in 2013 after a fair amount of research and they looked great. After signing up, they sent a confirmation email with all my account info with user-name and password in clear text. I cancelled immediately after seeing this, but I wonder if they are still doing it?

I ended up switching to Fastmail, which I still use and highly recommend.
