How I chose the best European email providers
I compared nine email providers registered in the EU or Switzerland and kept eight. Each one was checked on the same five points: jurisdiction and ownership, features (free plan, apps, calendar, storage, IMAP), price including your own domain, privacy (end-to-end encryption, open source, audits) and user ratings on Trustpilot. WEB.DE is not listed separately because it is run by the same company as GMX and works the same way.
