The manage viewer data option allows you to search for a user and then either remove that user or export that user's data.
To manage viewer data, follow these steps.
Open the Campaign module.
Click Manage Viewer Data in the left navigation.
Enter the user to search for. Typically this will be one of the following values:
Email - When using Campaign tracking and a Campaign lead form is used or with SSO integrations
User ID - When using SSO or custom integrations
Custom GUID - For anonymous users
External GUID - When a MAP integration is being used
If a match is found, select an action:
Delete Viewer Data - Remove viewing and lead data for the user
Export Viewer Data - Export the lead and view event data for the user. The lead data will contain the data that was entered into a Campaign lead form. The view event data contains all of the view events for the viewer.
