I built a landing page within the system. I cannot find it anywhere HELP
You may want to work with our support team on this one. They should still be available at 1-866-800-0004 Ext 2 or via chat.
If you are having trouble finding where it was created, there are some tests like filling it out with test info, and checking your contact campaign history after, to see which campaign goal it triggered. If it is missing, our support team should be able to investigate.
