I believe the easiest way to achieve what you’re trying to do is to use URL parameters and Converatble URL Targeting.
If you add a URL parameter to the path of your email link like:
so that your email link is http://www.yoursite.com/?greeting=hello, you can than use URL Targeting in Convertables to exclude any pages with ‘hello’ in the address.
Hopefully this achieves what you’re hoping for.
