Mailen

A desktop mail, calendar, contacts and notes client for Windows and Linux.

Mailen brings Gmail, Outlook.com and Microsoft 365 accounts into one window: mail, calendars, contacts, tasks and notes, side by side. It is a personal project, built and used by its author.

Mailen runs entirely on your own computer. It talks directly to Google and Microsoft on your behalf and has no server of its own, so your mail never passes through anyone else. Read the privacy policy for exactly what it reads and why.
