Google Analytics only gives out aggregated data, however. I would feel a lot safer if Google started running their own email analytics service, and blocked off everyone else. Oh, I can see the potential antitrust implications, but as a customer I still trust Google far more than any company whose sole purpose is to spy on my email. (Disclaimer: I also work for them. I don't think that'd alter my conclusion, but possibly how strongly I feel about it.)
