Marketing Admins can now view a list of who has subscribed to a campaign in the Administrator view instead of having to create a report. To see a list of subscribers:

1. In the side menu, click Create, then click the Campaigns tab. 
2. Find the campaign to view subscribers for, and click the number above Subscribers. 

A searchable list of subscribers appears, and clicking on a subscriber's name navigates to their respective Workspaces & Accounts page.
