Yes, enterprises can send multiple WhatsApp Template Messages outside a customer care session. These can be sent as part of the business initiated conversation. Once the business-initiated conversation with a given user is started, the business has up to 24 hours to send additional messages to this user without extra cost.
Beginning June 1, 2023, the business-initiated conversation category will be split into three new categories (each with their own pricing structure): Utility, Authentication, and Marketing conversations. All templates used to begin business-initiated conversations will be associated with one of those three categories. Additionally, the user-initiated conversation category will be reclassified as the service conversation category. All of the above-mentioned conversations will still last 24 hours.
If you send a template message, and an existing conversation in the template message's category does not already exist, a new conversation will start. If you send a template message while there is already a conversation in progress, and the category of the template and the category of the open conversation do not match, a new conversation will begin in the category of the template. Finally, any template messages sent during a service conversation will begin a new conversation in the category associated with the template.
