Lists and Smart Lists can be shared and referenced across workspaces for easy reuse from the Database.
Person partition rules apply (Smart Lists and static lists in a workspace only show people who are both members of the list and members of the current workspace).
Go to the Database.
Right-click a campaign folder. Select New Folder.
Assets can only be shared across workspaces if they are nested in a folder.
Drag and drop a list or Smart List you want to share into the new folder.
Right-click New Folder and select Share Folder.
Choose a Workspace to share with. Select Save.
Awesome! This list will now be available in both workspaces.
In Marketing Activities, you can only share top-level folders. In Database, you can share top-level folders as well as one level down.
