Meet Thunderbird

Thunderbird brings email, calendars, and contacts into a customizable application. Connect your existing accounts and choose whether to read them separately or through a unified inbox. Filters and organization tools help you arrange incoming messages around the way you file and review correspondence. The interface can be adjusted to suit those habits rather than requiring a fixed reading layout. Thunderbird is free and open source, with desktop and mobile applications in the wider project. Its central role is as a client for the accounts and address books you already use, keeping mail and appointments accessible together over time.
