Email tracker, read receipt and spy pixel blocker plugin for macOS Apple Mail
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.
Browse your inbox privately with images displayed once again.
Be informed. Say No To Spy Pixels.
On macOS 12, the default Mail Privacy Protection is highly recommended over MailTrackerBlocker for more comprehensive privacy guards.

Look for the small icon button in the email viewer. Tap to see which trackers have been blocked. Check out the tracker report for an aggregated 30-day view of who's tracking you.
Disabling "load remote content in messages" with MailTrackerBlocker enabled is redundant; re-enable this option for the best experience.
MailTrackerBlocker is a free and an open source project done on personal time. Thanks to all who have supported my project!
