01
Create a message sequence
Map the offer, order confirmation context, evaluation status where used, approved outcome, access instructions, reminders where appropriate, and support responses. Each message should have one clear purpose and an identifiable sender.
02
Design for failure states
Include delayed events, bounced or filtered email, changed addresses, expired links, device changes, accessibility needs, recipient confusion, duplicate contact, and cases where the order no longer qualifies.
03
Protect role clarity
Make it clear when the customer is interacting with the Shopify merchant and when a provider controls a card-related step. Support handoffs should not require the recipient to understand the entire provider stack.
