Got questions? We’ve got answers!

Customer engagement is evolving! Instead of one-way blasts to customers, communications are becoming conversational. Why? Because that’s what customers crave – 89% say they want two-way conversations over messaging channels.

Today’s tech-savvy customers want to ask questions right in the messaging stream on their preferred channel, and they want quick answers. This shift toward a more personal approach to communication is known as conversational messaging, or conversational customer engagement.

There are many messaging channels to choose from, and people use different ones based on age, location, and what’s most popular at any given time. It’s tricky to keep up.

Reaching customers across multiple channels can be a real challenge for businesses. Managing all those integrations and maintenance takes a lot of time. Then just when you think you’re on top of it, everything changes.

That’s why Sinch came up with Conversation API. Conversation API lets you use all those messaging channels with just one integration. And it has additional features to simplify the management of multiple messaging channels. Not only that, but because all traffic is routed through the same API, you get an overview of customer conversations across all channels, even if they switch channels mid-conversation!
Check out this article on Sinch Community that gives you a quick overview and short video tutorial on how you can test and get started using Conversation API from the Sinch Dashboard.

Smart Conversations is a collection of add-on features for Conversation API that passes received messages to the Sinch Machine Learning (ML) API engine. Depending on the features enabled, the ML engine will collect and analyze the message and, based on the type of message received, Smart Conversations can send “intelligent” automated responses.

The Sinch Smart Conversations functionality allows you to add artificially intelligent analyses to your Conversation API apps. Configure your webhooks to gain important insight into your conversations.
