Warning — The customer unsubscribes by writing over WhatsApp
If a customer replies with the word STOP, BAJA, CANCELAR or UNSUBSCRIBE (the whole message, not a phrase that contains it; it doesn’t matter if they write it in uppercase, lowercase or with accents), the Platform automatically marks them unsubscribed from marketing — without anyone on your team having to do anything. From then on, no campaign send reaches them, even if they’re still on a list. You can revert it by hand from the toggle on their record (section 4.2) if the customer asks through another channel.
