The pURL and QR Code elements are placed onto the creative template during the design process. If you are designing offline, leave space to add those elements once uploaded.

Select either of both of the elements from the toolbar on the left hand side within the Template Editor and drag them to their proper position on the template. You can then resize and/or edit as you’d like.
*Note: The template placement is for visual purposes only. The final setup is done within the Wizard when you are creating your Direct Mail Campaign.
