The Summary Results section allows you to view top level statistics for your profile. For example, you might want to view the average open rate over the course of a whole month.

To view a summary of your campaign results, go to campaigns then summary results.
From here you can select a date range for the search, minimum number of recipients, message type and grouping options.

Once you’ve selected your desired criteria, click search and you will then see the report. These results can be downloaded as a csv file, allowing you to create your own reports in Excel.
