Apparently big players like Google can preload and cache for others, somewhat mitigating img tracking/attacks.

Maybe clients could use Tor to limit the damage when img are needed but not necessarily trusted.

How would caching work if it is a (uniquely) _tracking_ pixel?

They cache the image when the email is received, not when it is opened.

Which would break tracking because open-rate would be 100% even if the user is on vacation.
