To communicate a new promotion to eligible members, a two-step process is required: segmentation and engagement.

1. Salesforce Customer Data Platform (CDP), now part of Data Cloud, is used for segmentation. It unifies member data from Loyalty Management with other sources to create a complete customer profile. This allows the creation of precise segments of "eligible members" based on criteria like tier status, point balance, or past engagement, which can then be activated for campaigns.

2. Salesforce Marketing Cloud is the engagement platform. Once the segment of eligible members is identified (either directly or via CDP), Marketing Cloud is used to design and execute the communication campaign across various channels, such as email, SMS, or mobile push notifications, to inform members about the new promotion.

A. Salesforce Cloud Intelligence: This is a general term for analytics tools like CRM Analytics. While it provides insights and dashboards on program performance, it is not the primary application for executing communication campaigns.

B. Salesforce Field Service Lightning: This application is designed for managing a mobile workforce, scheduling service appointments, and optimizing field operations. It is not intended for marketing communications to loyalty program members.
