WhatsApp error 131050: User has stopped reciept of marketing messages.

Code 131050 means the recipient has used WhatsApp's built-in control to stop receiving marketing messages from your business specifically. This is a user preference enforced by the platform, not a block: the person can still message you, still receive your utility and authentication templates, and still get your replies inside the service window. Only marketing templates are refused, and they are refused with 131050 until the user opts back in.

Meta is explicit that you should not retry. The message will not be delivered while the preference stands. The platform provides a user_preferences webhook that notifies you whenever a user stops or resumes marketing messages from your business, which is the mechanism intended to keep your own suppression list accurate.

Your account quality is not being penalized by this error itself, but continuing to attempt marketing sends to users who opted out is the kind of behaviour that eventually does affect quality.

Treat the user_preferences webhook as authoritative and wire it into your audience system so opted-out users are excluded before dispatch. Keep marketing and utility templates clearly separated so a user who opts out of marketing still receives what they need. Report opt-outs per campaign; a rising rate is feedback about content and frequency. Like other delivery-time failures it arrives in the statuses webhook, so a broken webhook pipeline hides opt-outs from you - worth ruling out with the webhook debugging guide. The platform-enforced drop for frequency rather than preference is 131049.
