The Event Wizard allows you to generate a report of Contacts who engaged in your Campaign(s). The results file contains a list of contacts email addresses with tracking events for the selected Campaigns. You can select which tracking events to include, as well as any related Contact and Custom Data.
The Campaign Report Wizard allows you to generate an overview report showing Campaign Statistics like Open and Click Through Rates from one or more Campaign. This report includes only overview statistics, rather than information about particular Contacts actions.
Both of these reports are available under Reports > Generate Report, and reports can be generated for one or more Campaigns. These reports can also be scheduled to run at regular intervals using the Calendar available under the Tasks menu.
