About this Add-on
SoundMail is an advanced notification sound manager for Thunderbird that lets you assign different sounds to different emails. Play custom or built-in sounds for incoming and outgoing messages based on flexible filter rules, account settings, or a global default notification.
The extension user interface is currently available in English (US), Russian, German, French, Spanish, Japanese, Arabic, and Simplified Chinese.
