Posteo
Posteo is an email service provider based in Berlin, Germany, offering paid email accounts for individuals and businesses. The service gained prominence during the aftermath of the post-2013 global surveillance disclosures, especially for its high standard security features and relative anonymity as it does not require any private information in the registration process.
Posteo offers support for DNSSEC/DANE and PGP. Additionally they offer two-factor-authentication via TOTP and use Extended Validation certificates and HPKP for the HTTPS connection.
