Vladimir Yakovlev publishes ElectronMail, an open-source desktop wrapper that brings ProtonMail’s end-to-end encrypted e-mail service to Windows, macOS and Linux. Built on the Electron framework, the application embeds multiple ProtonMail (and Proton Calendar) accounts inside a single, sandboxed Chromium window, adding native features the web interface lacks: system-tray unread counters, global search across mailboxes, offline message caching, automatic log-in through secure token storage, configurable keyboard shortcuts, and OSS-Fuzz-hardened encryption libraries. Power users can isolate each account in its own container, proxy traffic through Tor or custom SOCKS, and script actions via the exposed REST API. The codebase is TypeScript-heavy, reproducibly built on GitHub Actions, and signed with code-signing certificates to satisfy Windows SmartScreen. Typical use cases include journalists who need offline access to encrypted correspondence, privacy-minded professionals managing several Proton identities, and anyone wanting desktop notifications without keeping a browser tab open. Updates ship through GitHub Releases and community-maintained Chocolatey/winget feeds within hours of upstream Proton changes, ensuring the client never lags behind new web features or security patches. ElectronMail is available for free on get.nero.com, where downloads are served through trusted Windows package sources such as winget, always installing the latest release and allowing batch installation alongside other applications.
