You can personalize the newsletter by using Adobe Campaign personalization fields. To add a personalization field, open the personalization field picker by clicking on the button displaying the Adobe Campaign logo. You can then choose from all the fields that are available for this newsletter.
But the 'campaign' buttons do not work. I can click on them, they aren't greyed out. They just don't do anything. No errors either.
However the personalization fields do work for the RTE.
