Let me clarify my understanding and please tell me your recommendation...
What kind of behaviors are included in "Click Through"?
Are any links on an email included in? for example, clicking on the links of the external websites, landing pages, and that on the header and footer...
What kind of ways are there to track which links on the email a contact clicks?
In my understanding, it is available to use forms with hidden fields to track them (or via blind form submit ).
Also, in campaign scenario, if I need to judge whether a contact accesses to the landing pages from the email or not, I need to use "Submitted Form?" decision in campain canvas, not "Clicked Email?" decision, because "Click Through" tracks any links on an email and we cannot choose which links to track in campaign canvas.
