Messaging Quality

Sending messages is easy. Delivering them rapidly and consistently across the globe is more difficult. We've assembled an array of technologies to raise the bar on messaging quality, regardless of where your users are. We’ve built a Message Quality engine that, when coupled with our direct-to-carrier network infrastructure, delivers messages with the lowest latency, most consistently.

Always adapting, always improving

In order to optimise deliverability to thousands of networks around the globe, a platform needs to gather continuous feedback from customers who send large amounts of messages to a broad set of countries. Because we handle the messaging traffic from the world’s largest chat applications, we are uniquely positioned to optimise deliverability for the rest of our customers.

Quality optimisation

Our patented Adaptive Routing algorithm can measure real-time deliverability and route messages automatically to the best performing route. We process more than 60 million data points per month, giving us real-time insight into the best performing routes all over the globe, resulting in the highest possible delivery with the lowest possible latency.

The consistency of low latency and high deliverability over time is what sets us apart. We’ve found a way to reduce the volatility of deliverability, regardless of where on the planet your end users may be. Our Messaging Quality engine delivers a conversion rate that is so consistent, it typically varies by less than 0.03% in any given 12-month period!

Intelligent message delivery

Managing your identity and content is important when sending messages. End-users need a consistent and contextual experience and expect a rich character set within their messages, whether it’s full language support or expressing feelings via emojis.

Persistent sender

Within a messaging conversation, we’ll deliver your messages using the same sender ID, giving your end-user context during the entire dialogue.

Local number match

To enable a more familiar user experience and increase end-user engagement, the Vonage API platform can automatically send from a local pool of phone numbers for each destination.

Our platform automatically filters and selects the best performing gateway that supports unicode, delivering your messages with international symbols and emojis.
