I have a related problem, Rapportive: sometimes I send the same email individually to a large number of people, one after another. That way, each one gets an individual email but nobody's email address is exposed to anyone else. GMail puts all of these into a single thread -- and then Rapportive only looks at the first email in the thread, when searching for who to report on. So when I'm replying to email #20, Rapportive is showing the info for recipient #1. I'd much prefer to have Rapportive telling me about the email I'm currently working on, rather than the one at the top of the thread. Yes, I understand I can always click on the recipient to get Rapportive pointed in the right direction, but is that what you really want your users to do in that circumstance?

Thanks for the response Conrad!
Did not know that, thanks that could potentially resolve an issue but it does require a little effort.
Just something to think about :)
