Zinc Broadcasts that have been sent out can be managed and viewed in the Broadcast History tab of the Admin Console.
Clicking on an individual broadcast brings you to the broadcast summary page. It includes a preview of the broadcast, the number of people who have seen and/or clicked on the content link attached to the broadcast, the recipients of the broadcast, and whether they have seen it and/or interacted with it. It also shows who produced the broadcast and when it will expire.
The Broadcast Summary page can show you if the broadcast needs to be edited, and if the broadcast is reaching the desired audience. The icons in the top right corner of the broadcast summary page allow you to expire and edit the broadcast. (To learn more about editing and expiring broadcasts, click here)
