During the analysis phase of a delivery, the system is conducting checks on the target population, content validity, and other parameters without actually sending any messages. At this stage, if errors are detected, the delivery process has not begun, and no messages have been dispatched. Therefore, there is no risk associated with stopping the delivery to address any identified errors. It's actually a prudent measure to prevent the dissemination of erroneous messages.References:The analysis phase and its role in preventing the sending of erroneous messages are common features in email campaign management systems like Adobe Campaign Classic.
