About Mailspring
Mailspring is a desktop email client with a unified inbox, snoozing, scheduled sending, mail rules and reusable templates. Its interface is built with Electron, TypeScript and React, and a separate C++ sync engine runs locally on your computer.
Both the interface and the sync engine are published under GPLv3. Some advanced features belong to Mailspring Pro, an optional monthly subscription.
