Created by Andreas Müller.

Get started

Install ThirdStats from the Thunderbird Add-ons repository:

1. Start Thunderbird, open the main menu and click on Add-ons
2. Search for ThirdStats
3. Click Add to Thunderbird and give necessary permissions
4. Open the ThirdStats Popup in the upper right corner of the main toolbar and enjoy your email account stats

To properly recognize emails as sent, make sure to configure all email adresses you write from as Thunderbird identities for your email account. You can do so under account settings > select your account > click button more identities at the bottom and add or modify identities as you need.

Also keep in mind, that the processing of large mailboxes can take a lot of time.

Here is how ThirdStats looks like on the Thunderbird default dark theme and light theme on Windows:

Privacy and Security

ThirdStats runs entirely locally and will never contact, send or sell data to, any third-parties.

ThirdStats features require Thunderbird permissions to function, but will always seeks to minimise permissions where possible, and use granular permissions where available (Example: Thunderbird Permissions API does not currently provide for reading only message headers, instead of the entire email, including the body):

• Accounts: Access accounts and identities (read-only)
• Downloads: Export and download data as a file
• Messages: Access messages to create statistics (read-only)
• Storage: Store processed data (cache) for performance. Can be cleared or disabled at any time.

See the Security Policy for details how ThirdStats values your privacy.
