Communicating securely with Mailvelope
Mailvelope is a browser add-on that you can use in Chrome, Edge and Firefox to securely encrypt your emails with PGP using webmail providers
Why Mailvelope?

The browser extension Mailvelope provides end-to-end encryption for your existing email address. Encrypt your mails without having to change your email provider! Encryption and decryption takes place exclusively on the end devices. This means that your private data will never leave your device unencrypted.

Open Source
We value transparency: Mailvelope is the result of an open development process that can be observed at any time. In addition, security is evaluated by regular security audits. The source code published under a free license is available on GitHub. Mailvelope was funded by Internews and the Open Technology Fund, among others.

Mailvelope cooperates with the leading German email providers: Companies like 1und1, Freenet, GMX, Posteo, Telekom and WEB.DE are already using Mailvelope and are constantly working with us to make secure webmail even easier and more convenient.

Made in Germany
With a development time since 2012 and a quarter of a million users worldwide, Mailvelope has matured into a proven product. Mailvelope GmbH, based in Germany, offers support and services for open source encryption solutions.
Compatible with numerous webmail providers
So you can easily continue to use your current email account. And best of all: From now on, no one will read along. Because your information is only your business.
