When a link is received with no description on where the page is located or accessed, the URL will often times have the path to the page visible. For example if the page is https://sisacademy.org/page/giving/onboardinquiryautomation
This would be able to be found by navigating to:
  1. onMessage > Website > Site Name > Pages and Menus
  2. Expand the Giving Menu
  3. You will see a Page Titled onboardinquiryautomation you can click the Editing Wrench then select View Page to see the Full page URL which should match what you are seeing above but the .org changes to myschoolapp.com as you are now logged into the HTTPS app portion.
