Compliance and Guidelines
It is important to implement measures to stay compliant when using Viber channels. Non-compliance may result in being blocked from using the communication channel or being suspended permanently.
You must obtain consent from recipients before you send them messages. Recipients have the option to opt-out or block your sender.
The introductory message that you send to customers must not be promotional. Refer to the Viber approval section for more information.
Some countries have criteria for using Viber as a communication channel or sending messages to other countries. Refer to the Local Regulations and Features section for more information.
