Before uploading contacts, sending campaigns, starting automations, or initiating WhatsApp messages, you must have collected valid consent from each recipient where required.
Consent must clearly identify the business sending messages and should explain the type of messages a user may receive, such as support updates, service reminders, order updates, offers, product information, or other business communications.
You are responsible for maintaining proof of consent, including the source, date, method, and scope of the opt-in where needed.
You must honor opt-out, block, unsubscribe, or discontinue requests received through WhatsApp or any other channel. If a user replies STOP, UNSUBSCRIBE, OPT OUT, or otherwise asks not to be contacted, you must stop sending non-required messages to that user.
You must not re-upload, re-message, or retarget users who have opted out unless they provide a new valid opt-in.
