How does the Viber opt-in policy look like?

The recipient of messages must provide consent (opt-in) before a business sends any messages. Companies must retain proof of receipt of such consent. Users also need to be able to block the service from sending messages at any stage. Businesses can collect opt-ins by promoting Viber on their usual communication channels, incl. website, email, SMS, and more.
