you to monitor when recipients open your messages. It works with the self hosted
(pixel-track)[https://github.com/jv-barsuk/pixel-track] service.
This extension targets Thunderbird 128 and later. It creates one pixel per
message through `POST /api/pixels`, using the first recipient as `label` and
the subject as `campaign`, then inserts `/t/{token}` into the message.
The compose toolbar button inserts a pixel manually. Automatic insertion runs when a
configured rule matches. Multiple account identities and recipient addresses can be
selected. Recipient matching checks To, Cc, and Bcc fields. Plain-text messages are
converted to HTML only when insertion occurs for a configured recipient or through
the manual button.
