While you're mostly correct, they do not automatically download every image, it only initiates the download when you go to read the email. So they're still letting the sender know when you read the email, but yes they are masking the IP by using their own servers to download it. This can still be disabled if you use the setting to not download images, which is frustratingly unavailable in the gmail for ios app.


Ah, okay. I keep meaning to test this out myself. It's unfortunate that Gmail doesn't mask opens entirely.
