Mailspring

Desktop email with a unified inbox and optional follow-up tools

Meet Mailspring

Mailspring is a desktop email client for macOS, Windows, and Linux. Its unified inbox combines several accounts, with search across messages and tools such as custom signatures, themes, keyboard shortcuts, and spelling and grammar checks. Mail synchronizes directly between the configured provider and the computer.

Pro tools include scheduled sending, snoozing, follow-up reminders, templates, and activity tracking, with some available within free limits. The published source code provides another way to inspect or contribute to the application. Users can manage messages across accounts while keeping the relevant mail-provider configuration behind each one.
