Account owners who wish to see a record of activity in their organization and track all actions taken by admins across projects and email campaigns, may do so with Admin Event History. This can be useful for tracking changes made to surveys when there are multiple projects or multiple organization-level admins taking action.
To see the history log, navigate to any project's Settings tab and click Admin Event History.
This will display a table of administrator activity. You may change the Show setting in the upper-left to display a certain number of entries, and use the Filter in the upper-right to search for select data.
