The List Activity Summary is a summary of the subscriber activity on a particular list.

First select your List. (Go to Lists and click on Select List.) Then go to Reports, click on List Activity Summary and choose the date range for which you’d like the report. Click Create Report for this Date Range.

The report will list various types of activities (bulk load, bulk update, unsub request, manual add, etc.) and the number of times (volume) that type of activity took place. For more detailed information (email address, date and time) about a particular type of activity, go to Reports and click on List Activity Detail. There you can select the particular activity and process a more detailed report.
