Reply to comment by flutterbyasaurus in LPT: turn off "auto display images" in your email to stop hidden read receipt trackers by flutterbyasaurus

This is true, but with a caveat.

They don't block them. But they do route all images through proxy services. Because of that, the sender can see that the image was in fact opened, and if it is truly unique to your email they can see that someone (presumably you if you're the only one they sent it to) opened it. But they will not see your IP and thus be able to derive where you were when you opened it.

Yeah this was my understanding. The link to the image is unique to your email (it doesn't execute code lol) so that when the user loads it they know that email has been opened. I don't see how using a proxy would fix this because it's still going to use the unique link.
