PostMaster General keeps a log file of all activity on your list, including subscriptions and removals, so that you may view the activity on your list. For large log files, only a portion of the file is displayed.
Options are available to display additional parts of the file, or to display more lines at a time.
Your log file may be imported into a spreadsheet program so that additional analysis may be done. This example uses Microsoft Excel to create a graph showing the list size over time. View the log file as described above. Your browser may prompt you to save the file or choose an application to open it.
