Thundermail

Thundermail is a high-performance, "Sovereign" email client written in 100% native Rust. It is designed to be the memory-safe, privacy-first successor to legacy mail engines, eliminating the webview stack (Chromium/WebKit) in favor of a lean, immediate-mode GUI (egui), radical metadata protection (RFC 9788), and local-first AI intelligence.

In an era of pervasive email metadata harvesting and the vulnerabilities exposed by research like gpg.fail, Thundermail implements the most aggressive privacy standards from the user.js and 12bytes to ensure your communication remains truly yours.
