If you would like to use one of your developed Email stationery options, choose advanced when asked how would you like your messages delivered.
Then click on the Templates option in the top-left corner of the message content box.
Then, select the appropriate Content Template from the selection shown on the screen.
If you wish to replace the actual content in the existing message with your chosen template, place a checkmark in the box that reads “Replace actual contents”.
If you select the wrong template, use the New Page button to clear it.
