To send notifications to customers when their orders are ready for in-store pickup via SMS or email depending on their communications preference, Northern Trail Outfitters should use a Journey Builder multi-step journey with an API entry event and a decision split. A Journey Builder multi-step journey allows marketers to create personalized customer experiences across different channels and platforms. An API entry event allows marketers to inject contacts into a journey based on real-time events or data from external systems, such as order status updates. A decision split allows marketers to route contacts to different paths or activities based on their attributes or behaviors, such as communications preference. References:
