Which field should be included in a Field Group that captures loyalty details?

Including "Tier" in a Field Group that captures loyalty details is crucial as it categorizes the level of loyalty a customer has achieved within a loyalty program. Loyalty programs often have different levels or "tiers" such as Silver, Gold, or Platinum, which typically define the benefits a customer can enjoy, their spending thresholds, or their general engagement with the brand. By tracking the tier, businesses can tailor their marketing strategies, optimize rewards, and improve customer engagement based on where customers stand within the loyalty program.

While Reward Points, Membership ID, and Start Date are all important pieces of information regarding customer loyalty, the tier designation specifically encapsulates the customer's earned status and can be used effectively for customer segmentation, targeted communication, and personalized promotions, thus directly influencing customer retention and loyalty strategies.
