This is true - Gmail does this by loading them on their servers if I remember right. Pixel trackers do nothing these days if you send to Gmail addresses.


Hi Luke,

As far I know, this is not true. Gmail does load images through their servers but they do this just to scan for malware, not for stripping out pixel trackers. Pixel trackers still get loaded client-side on Gmail.

Actually I just looked it up and it’s been a thing since 2013. gmail.googleblog.com/2013/12/image...

I read the same post today when someone else referred to it me :)

In the post it never explicitly states that it strips out pixel trackers. It simply scans them for malware and serves than from a proxy. HEY does the same thing but actually removes the tracker from the email HTML content.

Google doesn’t say when the load the images from the proxy.

  1. They load the images when the email comes in.

In this case, the pixel trackers would be inaccurate and always gaslight marketers. They would get data saying the email was received right when the email was sent.

  1. They load the images from the proxy when the client requests the email to be viewed.

In this case, the pixel tracker would provide accurate data. The image is being loaded through the proxy in real time when the user is viewing it.
