The biggest advantage of messenger apps is that they're both synchronous and asynchronous, depending on the client and user behaviour. I'm working at a place that builds a customer service platform based on connecting messenger apps to a web client for agents to work in. The speedup you notice compared to Callcenter agents is astounding - they can handle multiple cases simultaneously, without having to wait for individual customers. They, in turn, can respond whenever they like to. It's really cool!
