How can a business estimate expected charges under the new model?

WhatsApp research suggests that there are typically 10-20 messages per user-initiated conversation.

Business-initiated conversations where no user reply is expected will typically result in a single conversation charge if all business-initiated messages are sent within the 24-hour conversation session. 

Rates per conversation will depend on the phone number the brand is messaging and are available on the rate card.
