Nylas Mail is an open‑source, extensible desktop email client built with Electron, React and Flux. It provides a modern web‑based UI and a plugin system for extending functionality.

Use cases

  • manage multiple email accounts on Windows, macOS or Linux
  • read, compose and organize email with a modern desktop UI
  • extend the mail client with third‑party plugins
  • synchronize email locally using the built‑in sync engine
  • customize the interface and workflow for personal productivity

When to choose

  • you need a cross‑platform desktop email client that can be customized with plugins
  • you prefer a web‑technology stack (React/Electron) for a familiar development environment
  • you want to explore or contribute to a historic open‑source mail client

When to avoid

  • you require active maintenance, security updates, or official support
  • you need advanced enterprise features not present in the archived version
  • you prefer a lightweight client without the overhead of Electron
