Hey! Ahh man this would be very cool. I started looking in to this, and it actually looks like we’re blocking a bunch of tracking pixels by default and without really alerting the user. We should probably make the functionality in the existing remove-tracking-pixels package optional and present it better. If anyone wants to pick this up, I think it could be structured / communicated almost exactly the way the messages-autoload-images plugin is!
Under the current implementation, what will happen if you open an email with mailspring tracking inside another mailspring client? Will the tracking be blocked?
