Don't forget the technical issues. Outlook Express 6 and most web based email providers don't allow javascript execution by default. I supose another email clients works the same way.

That is why I suggested that to make it work for newsletters, the publishers would have to submit the content of the newsletter before delivering, maybe using some programatic interface (Web services) and Google would return the HTML tags of ads targetted according to the newsletter content.
