I advertised taking a survey in my last email, and had someone fill it out. In the survey, I did not ask for contact information. So now I want to go into Marketo and track who the person was that filled out my survey. I've created an "Email Link Performance Report" that went along with the email campaign, so I can see what links were clicked by a certain amount of people. But I can't figure out how to see specific names that clicked on the links.
