What are Message Templates?
Message templates are the building blocks of campaigns and broadcasts. If you create a campaign or a broadcast, the content is stored as a message template. Bookboost will create one template for each language in a campaign or broadcast.
You can also create the message template first, then use that template to create a broadcast by clicking the three dots next to the name of the template, then by selecting either "Use to create a campaign" or "Use to create a broadcast".
