Thunderbird
An inbox that answers to you.
Bring email, calendars, and contacts together in an open-source desktop app that works with many mail providers.
Why it matters
Keeps a community-oriented email client available across desktop operating systems and email providers.
The honest heads-up
It is an email client, not an email hosting service. Check compatibility with your organization’s authentication and calendar requirements.
Your first small step
Install Thunderbird and connect an existing email account.
