Use Cases and Deployment Scope
We originally began using ManyChat for a free daily messaging service and course via FB messenger support after finding out that our text support couldn't reach certain countries. However, we ran into new issues with attempting to send "campaigns" as it was primarily intended for 1-way communication, and without a response from the recipient, the messages would no longer send. There were similar warnings with the broadcasts used for course updates, but many of them were able to be sent.
