Occasionally, we run experiments to help us assess the impact of messages on user experience and engagement on WhatsApp. These are standard practices on our platform and help us improve the messaging experience for you and your customers.
Ongoing experiments are described below and do not have a fixed end date. To protect the validity of the experiment and ensure the best possible business and consumer experience, we cannot provide any exceptions or opt-outs for these experiments.
Marketing message experiment
As of June 14, 2023, about 1% of WhatsApp users will not receive marketing template messages from any business, unless one of the following conditions is met:
there is an open conversation and inbound free between the customer and the business
If you send a marketing template message to a customer who is part of the experiment group, your message will not be sent and you will not be charged for it, since no conversation was created. Instead, you will receive a undelivered webhook status message containing an error code 130472, notifying you of the failure.
Attempting to resend the message will result in the same error. If you need to deliver the marketing template message to the customer, we recommend contacting the customer by some means other than WhatsApp and asking them to send you a message so you can resend the message within the customer service window.
