When Google (and presumably others) sell advertising based on keywords 
in your email, no third-party advertiser gets to see your message. 
Google has collected bids from many third parties, and runs an internal 
auction in which they have all the information, and they make the 
decision about who won and which ad to run.

The advertisers get to see statistics about how many times their ads 
were run, and how often each of their campaigns were winners.
