Use order facts deliberately
Campaign rules can consider products, collections, order value, dates, customer context, and lifecycle events. Use only the data required for the published offer and document where each decision is made.
Wait for the right decision point
An order event is not always final evidence of eligibility. Payment state, cancellation, fulfillment, return windows, and program policy can affect when a decision is appropriate.
Design for understandable status
Customers and support teams need consistent language for received, pending, qualified, not qualified, delivered, and changed outcomes. Clear status reduces avoidable contacts and disputed expectations.
