Does the WhatsApp greeting message send every time a customer messages me?

No. It is sent when a customer first messages you, and again when they message after 14 days of inactivity.

• A regular who orders every week will not see the greeting each time.
• The greeting needs an active internet connection to send.
• If Meta Business Agent is connected, greeting messages are switched off automatically.
• Keep the greeting short: who you are, hours, and how to order.
