Your order and fulfillment systems supply shipment and delivery data. Blocx is the message delivery layer, not a shipment-tracking or order-management service.
Can we send updates through more than one channel?
Use the channels supported by your plan and the intended content and recipients. Your application chooses the channel and any permitted follow-up; do not assume an automatic cross-channel sequence is created for you.
How can support see whether an update was delivered?
Associate message identifiers and documented status feedback with the order record. A successful submission alone should not be shown as confirmed customer delivery.
How many status changes should trigger a message?
Choose changes that help the customer act or understand the order. Your application should suppress redundant internal events and avoid sending a new notice for every fulfillment-system update.
Answer the next order question before it becomes a ticket.
Choose one milestone or exception, connect the real event, and give the customer a clear path to the latest order information.
