Join Us in Securing Digital Communications Worldwide with Mailvelope

🔐 Who We Are & Our Vision
Greetings from Mailvelope! Rooted in the belief that privacy is a fundamental right, we are committed to providing a highly usable open source software solution that empowers individuals and organizations to protect their email communication through end-to-end encryption.

Mailvelope is an established and well-known provider of open source encryption software for over 10 years.
Distributing a browser extension, we were able to show that PGP works in the browser. In particular, we successfully managed to handle private user data in browsers in such a way that the email service providers do not have access to it.
This has been proven in a series of security reports and audits. Today, we have a growing user base of currently 300,000 users.

In the German market, we succeeded in bringing the two largest German email providers on board. Both GMX (18M users) and WEB.DE (23M users) have integrated the possibility to use Mailvelope since 2015.
We also keep receiving positive feedback from the open source community.

🚀 Our Current Endeavors
At Mailvelope, we are constantly evolving and innovating to meet the needs of our users. Our recent and upcoming projects include seamless integration into Microsoft 365 for Outlook encryption, development of mobile device solutions, private key backup features, key escrow, encrypted email signatures and subject, secure inbox / anti-phishing features, and much more. These enhancements are designed to make encrypted communication more intuitive and accessible, ensuring that sensitive information remains confidential.

💡 Why Your Sponsorship Matters
Your support through GitHub Sponsors is not just a donation; it's an investment in the sustainability of open-source software and the privacy of digital communications worldwide. Here’s how we plan to use the funds:
