To implement collated summary emails for consignments rather than sending individual emails for each consignment and inundating recipients' inboxes with multiple emails, a collated summary email provides a consolidated overview of all relevant consignments within a given timeframe. The summary email can include key details such as consignment numbers, item descriptions, quantities, and any notable remarks or exceptions. By condensing the information into a single email, you can quickly scan the contents, saving time and reducing email clutter.
