I think most of us know that Google reads our email. I decided to run some tests to try and figure out how they read it. Honestly I think they could do some improving on it.
I sent some mail between hotmail and gmail. It immediately picked up on what "we" were mailing about. Then, as often happens with email, I changed the topic of our conversation in the email. The targeted advertising did not change.
Only if you change the subject of the email does it change advertising.
Just thought y'all may be interested.

That's really interesting. So if you title all your emails with a topic you're totally into, you'll get the kind of ads you really want. I think I'll start titling all my emails "Italy travel"
Kind of...
Do a little experiment. The subject actually does not matter. It is the body of the first email. You can send an email subj: new car and then in the body type something like "I am looking at a bmw or mercedes." It will spit out ads based around those makes. They actually read the body. They only read it once though....unless you change teh subject.
