Can I ask for feedback with a utility message?

Yes, if the request is about one specific order or visit and has no promotion. A general survey, or one with an offer, is marketing.

• Meta says a general or generic request for feedback will not be approved as utility. It must be about a specific order or interaction.
• Meta's utility examples include a note after delivery that quotes the order number, and a request about a recent visit to a store.
• Add a discount or any promotion and it becomes mixed content, which Meta treats as marketing.
• Marketing costs more: ₹0.8631 a message in India against ₹0.115 for utility. Meta approves a misjudged utility template as marketing.
• Send it only to customers who opted in to WhatsApp messages from you.
