Thunderbird Add-On Overview

Spam Experts provides a Mozilla Thunderbird add-on to report any spam not blocked by the Spam Experts filter.

See Report Spam Using the Thunderbird Add-on for details on reporting single or multiple messages as spam using the add-on.

Supported Versions

We support Mozilla Thunderbird versions 78.0 and newer.

We no longer support any older versions of Thunderbird. However, between version 68.5.0 and 78.0, you may use Configure Thunderbird to Access the IMAP Quarantine instead.
