I contacted Cranemail and they are a US company registered in Wyoming. Oh well. I think leaving your email on someone else's server isn't really the right way to do it anyway. It's gotten very difficult to self-host SMTP, but self-hosting IMAP isn't too bad, or you can just regularly pull and delete your email from a hosted IMAP, transferring it into your own and possibly making an encrypted backup.

I think the company is Canadian but I haven't checked. BuyVM was defnitely Canadian and was run by the same guy. You have to assume that email is never private anyway, since the person at the other end probably is on gmail, may have used CrapGPT, and so on.
