  2. Select Pushpage issues
  3. Edit the appropriate Pushpage
  4. Click Edit within the text box
  5. Change the Insert dropdown to be one of the User Placeholders that you want

Note: If you are sending a Test Pushpage, this will NOT display the User's Placeholder. Instead you can send a live issue to a Distribution group with just a Static User and you will see how the Placeholders display within the issue.
