I'm using https://soverin.net for €29/year (€39 if you don't have your own domain) to limit my google dependence. Added benefit that they are based in EU. Disclaimer: our company works with them so I'm definitely biased.
Looks nice, but my worry is if they'd be alive in a year. I have actually used an e-mail provider before that's no more.
I'd like the European level of the data privacy but also a company that is set to live long, and the web site looks too much like a startup that can disappear tomorrow (as in "it didn't grow enough, who cares, it's just a web address, let's kill it and do something else.")
