Build your audience for WhatsApp Chat Messages in Contact Builder.
When opting-in customers, consider these best practices.
- If you skip importing contacts, your messages don’t send.
- Flag opted-out contacts so that Journey Builder doesn’t send messages to them.
- Use Journey Builder to send emails or SMS messages to ask customers to opt in, and then collect the subscribers in a data extension.
- Customers have to opt in only to your WhatsApp channel and not every template message that you use.
- In Contact Builder, create a contacts import definition.
- Create an audience for WhatsApp.
