You need to run an email link performance report.
Email performance will show you more of how the email performed in a broad sense, while email link will show you what links are performing the best.
You can create these reports either in the program itself, or if you want a broader view in the Analytics tab. If you create it in the program, it will by default show you all emails in that program. If you do Analytics, you can select exactly which emails you want to see.
Hope that helps!
