We are planning to send an email campaign with three separate URL click options. Is it possible to see how many people click on each link?
An Email Link Performance report in Analytics will show you the numbers for these links, but if you want to see exactly who clicked each link then a smart list with a Clicked Link In Email filter and Link constraint within that filter would be best.
Reports are focused on numbers, and the smart lists will give you the details of who clicked it.
Yes, the email perf report will show you the total count, but it also includes people who click more than once.
The email link perf report will also do this and show you which links were clicked.
