Managing unsubscribes and blocks
Handle customers who opt out or block your WhatsApp number.
When customers reply STOP or block your number, SendBlix updates their contact record to prevent future marketing messages.
How it works
SendBlix monitors inbound messages for unsubscribe keywords (STOP, UNSUBSCRIBE, etc.). When detected, the contact is marked as opted out. You can customize the unsubscribe keywords and the confirmation reply.
