Welcome to MailCopilot

MailCopilot is an AI-native desktop email client designed for speed, privacy, and simplicity. It connects to your existing email accounts via standard IMAP/SMTP protocols and keeps your data under your control. With a built-in AI assistant at its core, MailCopilot helps you read, write, and manage email faster than ever.

Key Features​

  • Multiple accounts -- connect several email accounts and switch between them instantly, or use the unified inbox to see all mail in one place.
  • Fast, native experience -- built with Electron and React for a responsive desktop interface with light and dark themes.
  • Privacy-first -- emails are rendered in a secure sandbox with external images blocked by default. Passwords are stored in your system keychain.
  • Conversation threading -- related messages are automatically grouped into threads for easier reading.
  • AI assistant (optional) -- a built-in assistant powered by Claude can summarize emails, draft replies, and help you manage your inbox.
  • Keyboard shortcuts -- Gmail-style and Outlook-style shortcut presets let you navigate and act on messages without touching the mouse.
  • Scheduled sending -- write a message now and schedule it to be sent later today, tomorrow morning, or at a custom date and time.
  • Offline mode -- download messages for reading without an internet connection.
  • Drag-and-drop -- move messages between folders by dragging them in the sidebar.
  • Desktop notifications -- get notified about new mail even when the window is in the background.
  • 6 interface languages -- English, Russian, French, German, Spanish, and Italian.

Supported Platforms​

MailCopilot is available for Linux (AppImage, deb, rpm) and Windows (installer). A macOS version is planned for a future release.
