A outfit like Yesware provides rough location data w/ their pixels.

FWIW, they're partially funded by Google Ventures- perhaps there is some type of technical compromise that doesn't break geographic tracking completely: http://www.yesware.com/blog/2012/07/18/how-does-yesware-trac...

Yes, but it is unclear whether their servers will load them regardless of whether or not they're sent to my browser.

But surely ALL emails to @gmail.com are received.
