I believe this is how they fetch images without meaningfully accessing tracking pixels.
If everything send to gmail is opened upon arrival and cached, you know nothing about when or if the recipient actually opened the email.
- upofadown 5y agoLast time I looked into this, Gmail was not loading and caching images. Is there any evidence that this has changed? What is being described here is likely being done for some other purpose.
- wodenokoto 5y agoGoogle claimed to do that. > Instead of serving images directly from their original external host servers, Gmail will now serve all images through Google’s own secure proxy servers. Https://gmail.googleblog.com/2013/12/images-now-showing.html
