No, they don't. This spy pixel crap is exactly how privacy-invading tools like Superhuman get read receipts. Some even show the city and country that the e-mail was read from by GeoIP-reversing the IP address that accessed the pixel. This practice needs to be ended, and IMO is a far worse violation of privacy than GDPR or anything else people are making noise about today.
- tyingq 6y agoGmail does say they use image proxies. Is there some specific way those tools are getting around this? Just unique image names per sent email? https://gmail.googleblog.com/2013/12/images-now-showing.html https://gmail.googleblog.com/2013/12/images-now-showing.html
- dheera 6y agoI wasn't aware of the proxy, so I may be wrong about the GeoIP aspect, but it's possible other mail clients don't proxy, so it's something to be wary of nonetheless. They use unique URLs for each e-mail and recipient, so when the proxy makes the request, they can trace it down to which exact e-mail was opened.
