Why Bulwark Webmail?

Bulwark Webmail is a modern, self-hosted webmail client built for Stalwart Mail Server. It gives users a polished, full-featured email experience - mail, calendar, contacts, file storage, and more, without relying on Big Tech.

Built with Next.js, TypeScript, and the JMAP protocol, Bulwark is designed to be fast, secure, and privacy-respecting from the ground up.
