mail.de
Germany
German email provider with over 25 years in the business and a hard no on selling your data.
European Alternative to:

mail.de is a German email provider that has been running since 1995, making it one of the older independent players in the space. It is operated from Germany, which means it sits under German and EU data protection law, including the GDPR.
The service offers webmail, IMAP and POP3 access, and custom domain email. The free tier is ad-supported, while paid plans remove ads and give you more storage. It is aimed at people who want a straightforward email account without handing their inbox over to a US tech giant.
mail.de is not end-to-end encrypted by default the way Proton Mail or Tutanota are, but it does encrypt data at rest and in transit. It is a practical, no-frills option for German users who want a local provider with a long track record.
