MailTrackerBlocker is a plugin (mailbundle) for the default Mail app built-in to macOS. Email marketers and other interests often embed these trackers in HTML emails so they can track how often, when and where you open your emails. This plugin labels who is tracking you and strips out spy pixels out of the HTML before display, rendering the typical advice of disabling "load remote content in messages" unnecessary.

Be informed. Say No To Spy Pixels.

MailTrackerBlocker is a macOS Apple Mail plugin (i.e. mailbundle) to block read trackers disguised as "spy pixels".

Most commercial trackers can be reliably blocked through a blacklist of known URL patterns. Failing that, MailTrackerBlocker applies a generic regex filter for 1x1 images. Read more about how email pixel tracking works.
