What Clicked Link in Email rule are you using? And what isn't working exactly? The Link ID is "download" here.
I get that, but I clicked the link in question to get to that landing page. I'm trying to figure out how to get it to record the link clicking activity. Link tracking is checked in the email editor.
You have to start with a Smart List on Clicked Email (no constraint). Only after determining that it has results can you add a constraint.
In general you must use proven activities, not ones you hope happened!
