Click tracking is an option which is disabled by default. In order to enable clicks on links detecting, go to a specific Campaign -> Settings -> General Settings
To find those prospects who clicked on the links inside your template, go to Campaign -> People -> add new Filter and search by Status: Clicked
Hit 'Apply' if you need to temporary save this filter list - it'll be automatically removed by your next session.
Hit 'Save' to permanently save the filter list so it also could adjust the numbers if there are more people clicked.
You can also find those who clicked in the campaign's Stats by switching the Live toggle
Note: Reply tracks only those links that were added to the email template using the Insert/Edit link button in the template editor.
