Overview

Thunderbird is a solid open-source email client for Windows with a native installer. It supports multiple accounts, spam filtering, message tags, and built-in OpenPGP encryption for secure email communication.

The Supernova redesign brought a unified sidebar for mail, calendar, tasks, and chat. Extensions from addons.thunderbird.net add further customization.
