Opt-In
Opt-in is a customer explicit permission to receive WhatsApp messages from a business. WhatsApp requires opt-in before a business messages someone, and it is the foundation of compliant, effective WhatsApp marketing.
Businesses collect opt-in through click-to-chat links, website widgets, checkout, QR codes and by asking existing customers. The opt-in should be clear about what the customer will receive.
Messaging people without opt-in leads to blocks, a falling quality rating and possible bans.
