What is Nexmo Adaptive Routing?


  • What are the features of Nexmo Adaptive Routing?
  • What are the benefits of Nexmo Adaptive Routing?


In order to identify the carriers who provide the best performance, Nexmo continually tests the routes used to deliver SMS and Voice.

Those tests are run automatically by Nexmo with the aid of the Adaptive Routing algorithm.  

Using Adaptive Routing the Cloud Communications Platform actively re-routes messages through different carrier routes and ensures optimum delivery for your messages. The route choice is made using millions of real-time conversion data points.

Message delivery indicators are:

  • Delivery receipts - in most instances DLRs are indicative of handset delivery. Unfortunately, delivery receipts are not always a reliable measurement of SMS reception. Nexmo uses conversion data as our main quality measurement.
  • Conversion data - by continuously sending a small amount of traffic to carriers, we see which route is performing best at a point in time and automatically rerouted accordingly. This analysis is carried out every 5 mins using data points from the previous 15mins.

With Adaptive Routing in conjunction with the Conversion API we achieve increased deliverability, reduced latency, higher conversion rates and increased stability.
