Yes, that’s possible. Go to ‘Manage posts’ and click on the ‘Published’ tab. After clicking on ‘Stats’ at the bottom of the message, an overview will appear. Here you can see per promoter whether a message has been published. If a message is not published, you can read the cause by placing your mouse on the question mark next to ‘Failed’. If a promoter has rejected a message, it is indicated in the list.
