A customer's withdrawal of consent to receive WhatsApp messages from a business.
Opt-out is the process by which a customer tells a business to stop messaging them on WhatsApp. It can happen explicitly — a customer replies "STOP" or taps a stop-promotions option — or implicitly, when a customer blocks the number or reports messages.
Businesses must honor opt-out promptly and stop sending, especially marketing messages. Failing to do so leads to blocks and reports, which damage the phone number quality rating and can trigger restrictions.
Maintaining a clean, respected opt-out process is both a compliance requirement and a practical way to protect deliverability and brand trust.
Honoring opt-outs keeps you compliant and protects your quality rating — ignoring them quickly drags a number toward restriction.
