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.

You can install
MailTrackerBlocker.pkg directly from the releases page but I strongly recommend installing as an Homebrew Cask for ease of updating.
$ brew install mailtrackerblocker
Preferences > General > Manage Plug-ins... > check "MailTrackerBlocker.mailbundle" > Apply and Restart Mail. Note that you'll need to do this again for each update.

⚠️ Disabling "load remote content in messages" with MailTrackerBlocker enabled is redundant; re-enable this option for the best experience.
If you installed with Homebrew:
$ brew uninstall mailtrackerblocker
If you installed the
osascript -e "quit app \"Mail\"" sudo rm -r /Library/Mail/Bundles/MailTrackerBlocker.mailbundle sudo rm -r /Library/Application\ Support/com.onefatgiraffe/mailtrackerblocker sudo pkgutil --forget com.onefatgiraffe.mailtrackerblocker
