I don't think these changes at Apple will ruin your use case at all. From what I've read, will load images privately, which means it'll probably hide IP (as they've mentioned) and details about browser etc. It'll still need to load the image. If you were to create a specific image for every sent email, you can still see whether that image was accessed by Apple. Unless they create something like a CDN to cache every image people receive, even if they don't open the email, you'll still be able to see whether an email was opened. You just won't be able to see from where, or from which browser, which seems unnecessary in your use case. To me this seems like the only actual negative impact could be on LE, who sometimes use this technology to find missing persons. Edit: I was wrong, upon further reading they do get the images for every email, even ones that weren't opened. Seems wasteful (the majority of my email never gets opened), but it's a great implementation. Guess it's time to give Apple Mail another try.
