A trigger link can be put in emails or texts and it allows you to track specific customer actions.
i.e. I want to track the contacts who go to my website.
Create a Trigger Link
Under "What should trigger this rule?", select "Trigger link clicked"
Select "Add filter" and select "Trigger Link". Then choose the name of the Trigger link you just created.
Under "What action should we perform?", select any action that you want to take place after the trigger link is clicked. You can add a tag to the contact and call it "trigger link clicked", you can add them to a pipeline, you can add them to an email campaign that says, "thanks for visiting________.com" There are many different actions you can complete here.
Add the trigger link to an email or SMS
