Runbox
Norway
Norwegian email service with privacy as the default, not an add-on.
European Alternative to:

Runbox is a Norwegian email provider founded in 1999 and headquartered in Oslo. It runs on servers powered by renewable Norwegian hydroelectric energy, which is a concrete and specific claim the company makes about its infrastructure.
The service offers web-based email with support for IMAP, POP, and SMTP, so you can use it with any standard mail client. Plans vary by storage and the number of email accounts and aliases you can create. There is no advertising and no scanning of your email for targeting purposes.
Norway sits outside the EU but is covered by strong privacy laws, and Runbox has historically made its legal jurisdiction a selling point for users who want their data away from US or UK providers. It is a small, independent company rather than a subsidiary of a larger tech group.
