A message campaign can be based on either:
- a freeform message: you can define the message content at the time of sending, no need to be pre-approved to be sent. You can send this newsletter to any channel except for WhatsApp.
- a message template approved by WhatsApp: allow business to use pre-created and approved templates to send structured messages to customer who have agreed to receive messages. This type of message can be sent to any channel since Sinch Engage adjusts the content of the template according to the format of the message allowed in each channel.
