> Not quite, the sender still doesn't get location and your browser fingerprint.
Yes, but the key question was about the open rate.
The statement:
> I thought Gmail's solution to this was to always download every image in your email and then proxy the image from their own servers when you view it. This results in a meaningless 100% "open rate" for Gmail
is incorrect because
a) GMail does not always download every image in your email
