@clickhere @drwho @alice @protonprivacy I could not, so I did some digging for you anyway, and here are the providers I would start with to narrow down the most suitable ones for me, if I was looking. Ones marked with an asterisk are those that I vaguely recall being on my original research list:
- https://posteo.de (Germany)* Do read their sustainability section. I LOVE IT! "Posteo employees can have their bike repaired by a mechanic free of charge."
- https://mailfence.com (Belgium)
- https://mailbox.org (Germany)*
- https://tutanota.com (Germany)*
Points to consider for each are features/restrictions/allowances, pricing, security practices, jurisdiction of data storage, how well they are ranked by security professionals, and others. I hope this helps with a starting point.
