Coordinate with your business users to plan your campaign launch at a specified date and time. With the proper permission set, you can set up an Auto Send for a Campaign. At the selected date and time, all campaign members not yet sent to and not part of a scheduled or bulk send are added to the Auto Send campaign journey. Your business users can add up to 25,000 members for an Auto Send campaign. If more than one campaign is scheduled by the same person for the same time and date, your business users can still send to a total of 25,000 members.
