Thunderbird seems to block ALL tracking links from CONSTANT CONTACT (specific return tracking server is r20.rs6.net--see copy of error message attached). Configuration: Windows 10, Thunderbird 115, Firefox 123. Ublocker was Firefox extension but issue continued with Ublocker uninstalled. Bit Defender & Bit Defender VPN tested installed and uninstalled. Also tried various configurations of Firefox and Thunderbird settings/privacy & security.

That domain is blocked by Firefox Enhanced Tracking Protection.

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

  • click the shield icon for more detail and possibly disable the protection

You can check the Web Console for relevant-looking messages like blocked content.
