Issue
You want to run a report that will show you which leads/people clicked on links within a specific email.
Solution
The Email Performance report will show click rate and what links are in emails, but not which specific leads leads clicked on a link. To see that, you can instead create a Smart List. Using the filter of "Clicked Link in Email," you can then pick the desired email and the results of the Smart List will show you which leads clicked a link in the desired email.
