I have added the <preferences>this will be a link</preferences> link into the email and run a test email from Step 4.1. - what i get is the following:
"Subscriber Preference Center
When you send this campaign, this page will display a preference center allowing your subscriber to update their preferences or unsubscribe from your list. You can test this by sending yourself a test campaign in Step 4.1."
That means everything is working right - as the message explains, when you send the actual campaign (not a test) it will show the preference center page.
Actually, Mathew, if you believe that is the correct behavior then the message is really misleading.
It specifically says "You can test this by sending yourself a test campaign in Step 4.1." Well...that is exactly what tonycharman and I did. And...we receive that message...not the actual Preference Center page!
To make this statement correct in that situation -- actually sending a test campaign -- your team should remove the last line. Better, it should allow us to actually preview the Preference Center page.
