Email Encryption

All email applications on this page support the OpenPGP standard either directly or with additional software. The authors of this webpage are not actively participating in the development of each of these third-party apps. No security audits have been done by us and, thus, we cannot provide any security guarantees.

A lot of webmail providers support email encryption via the OpenPGP standard using Mailvelope. The Mailvelope website provides a list of supported webmail providers.

Providers with help pages:

Webmail Provider with In-Browser Cryptography

In contrast to the previous section, the following webmail providers do not require the installation of additional browser plugins, instead OpenPGP is implemented in JavaScript provided directly by the website. While these are easier to set up and provide basic security guarantees with OpenPGP, some people don’t consider these “end-to-end secure”.
