# Wino Mail (open-source email and calendar app)

> Wino Mail is a free, open-source email and calendar app for Windows. Built-in Mail & Calendars app clone for Windows. It has 1,597 GitHub stars and is released under the GPL-3.0 license. Its source code is on GitHub at bkaankose/Wino-Mail.

Native mail and calendar client for Windows. I'm a big fan of Windows Mail & Calendars due to its simplicity. Personally, I find it more intuitive for daily use cases compared to Outlook desktop and the new WebView2 powered Outlook version. Seeing Microsoft deprecating it dragged me into starting to work on Wino a couple of years ago. Wino's main motivation is to bring all the existing functionality from Mail & Calendars over time without changing the user experience that millions have loved since the Windows 8 days in Mail & Calendars.
