You can see any scheduled mailings in the Container Activity Report.
You can get to this report by going to the root level container of the client's system (top most level), clicking on "Container" (in top menu), then "Activity". Select the date range, check the box that says "Include Sub containers" to see all containers, and then click on the "Scheduled Emails" tab.
Please note: This will only show emails that are scheduled to send via the "Send Later" functionality - not triggers.
