About Thunderbird
Thunderbird is a free email and calendar app for Windows, macOS and Linux. It is part of the Mozilla family of projects and is funded by donations from users.
What it does
Thunderbird manages several email accounts, either in a unified inbox or in separate views. It includes a calendar, contacts and tasks, so you can keep messages and schedules in one app. Filters help organise incoming mail, and tags let you mark important messages and find them later. The interface can be customised with themes and add-ons to match your workflow. A mobile app is also offered for Android, so you can take your messages with you.
Key features
- Unified inbox or separate account views
- Calendar, contacts and tasks in one app
- Message tags and filters
- Themes and add-ons
- Mobile app for Android
Who it's for
Individuals and teams who want a private desktop mail app with a long track record. It suits people who juggle several accounts and want more control than a webmail page gives them.
Pricing and good to know
Thunderbird is open source and free to download and use. The project is funded by donations and does not sell ads in your inbox. Your email accounts stay with your existing providers. Some advanced add-ons come from third parties and vary in quality, so read reviews and check update history before installing them.
