Hi Erin,
If it's not appearing on your smart list, there might be a chance that the link wasn't clicked. Check this against the email link performan report for your email campaign. If the link doesn't appear there, then the link wasn't clicked. One of the things that I also use is Google Analytics and anotate a particular day that we have an email campaign, and look for any spikes in page views, particularly for that day and that particular url.
