I successfully set up a landing page with a corresponding thank you page. I also created a form to embed on my own webpage so people can sign up there. When people sign up using the form, instead of the landing page, they still get the incentive email. But I can't find a way to make a custom thank you page for them to land on when they hit "confirm subscription" in the email. I tried linking to my existing thank you page but it actually takes them to the landing page. Any tips?
