If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Was it clear which item the notification referred to?
Did the message arrive at a useful time?
What availability information was missing?
Was the next action understandable?
What would make the message more useful?

Author notes / illustrative keys where applicable:
1. Item recognition determines whether the recipient can connect a restock message to the intended product or variant. Make the verified item identity clear without implying stock has been reserved.
2. Useful timing depends on whether the customer still needs the item and can act. Investigate the message's context rather than assuming faster notifications necessarily improve purchase decisions.
3. Missing availability detail reveals uncertainty about variant, quantity or purchase conditions. Explain what the service actually knows while avoiding guarantees that stock will remain available.
4. A clear next action distinguishes checking availability from placing an order or requesting another update. Match the instruction to the actual destination without implying an automatic reservation.
5. A useful improvement addresses the specific decision left unresolved by the restock message. Test accurate item context or action guidance rather than promising priority access the service does not provide.
