To meet the requirement of targeting loyal and engaged customers (platinum-tier customers visiting investment pages more than three times in 24 hours) and sending an immediate email offering a private consultation, the best solution is to use a streaming insight with a data action into a journey in Marketing Cloud Engagement . Here's why: Understanding the Requirement The company wants to identify platinum-tier customers who visit their Investment pages more than three times within a 24-hour period. Once identified, these customers should immediately receive an email offering a private consultation. This requires real-time monitoring of customer behavior and triggering an automated response. Why Streaming Insight with a Data Action? Streaming Insights for Real-Time Monitoring : A streaming insight in Salesforce Data Cloud monitors customer interactions in real time. It can detect when a platinum-tier customer visits the Investment pages more than three times within 24 hours. Data Actions for Immediate Response : A data action allows you to trigger specific actions based on the insights generated. In this case, the data action would send the customer's information to a journey in Marketing Cloud Engagement to initiate the email campaign. Journey in Marketing Cloud Engagement : Marketing Cloud Engagement journeys are designed to automate personalized marketing activities, such as sending transactional emails. By integrating the streaming insight with a journey, the system can immediately send the email offering a private consultation. Steps to Implement This Solution Step 1: Create a Streaming Insight Navigate to Data Cloud > Insights > Streaming Insights . Define the criteria for identifying platinum-tier customers who visit the Investment pages more than three times in 24 hours. Step 2: Configure a Data Action Set up a data action that sends the identified customer's information to Marketing Cloud Engagement. Ensure the data action includes relevant details (e.g., customer ID, email address). Step 3: Build a Journey in Marketing Cloud Engagement In Marketing Cloud Engagement, create a journey that listens for incoming data from the data action. Configure the journey to send a personalized email offering a private consultation. Step 4: Test and Deploy Test the entire workflow to ensure that the streaming insight triggers the data action and that the email is sent immediately. Why Not Other Options? A . Calculated insight with a data action to a Marketing Cloud Engagement transactional email : Calculated insights are not designed for real-time monitoring. They are better suited for batch processing or periodic calculations, making them unsuitable for this use case. B . Rapid segment to a data action journey in Marketing Cloud Engagement : While rapid segments are useful for quickly grouping customers, they do not provide the real-time detection required for this scenario. C . Standard segment with activation into Marketing Cloud Engagement : Standard segments are static or periodically updated and cannot respond to real-time customer behavior. Conclusion By using a streaming insight with a data action into a journey in Marketing Cloud Engagement , Cumulus Financial can achieve real-time monitoring and immediate engagement with its loyal customers.
