Verification Activity is the step that prevents the automation from completing the automation instance and delivering an inaccurate report if some agents have not created their data extensions in time. This activity verifies that a data extension meets certain criteria, such as row count or field value, before proceeding to the next step. If the criteria are not met, the activity stops the automation and sends an email notification. Data Extract Activity is a step that extracts data from a data extension or data view and places it in a file on the Enhanced FTP server. Wait Activity is a step that pauses an automation for a specified period of time.
