Why do businesses integrate with’s API?
In a world where SMS has become an extension of a software provider’s solution, the choice of provider for an API integration becomes less about the SMS and more about what is supporting your business. This is where differentiates itself in operational terms. Rather than list what we see as benefits, let’s review what reasons our clients shared as they moved their SMS business to

Capacity planning
One gambling client outlined that if there was large send to go out because of a national event they wanted to promote then they needed to highlight this to their previous supplier to ensure the messages could go out, meaning a lot of preparation before the event itself. With a technology stack that sends hundreds of SMS per second, that cumbersome activity has gone away.

Highly available architecture
One of our clients moved as their previous provider offered a 99.5% up time guarantee. This equates to 1.83 days a year of unplanned downtime, not much of a guarantee when you have a key message to send out and your reputation is on the line. With an operational history of over 99.999% up time (which is five minutes a year of downtime) you know the platform is going to be there for you.

Innovation & relationships
How many businesses boast about innovation, though behind the scenes, they partner with mediocre SMS suppliers? As well as direct connections with UK network providers, we also have relationships with leading providers of other digital messaging channels – think RCS (Rich Communication Services) and social messaging platforms.

What differentiates you from your competition?
When you compete with other software providers, you may share an ideal of forward thinking and solution innovation. However, what you need to back this up with is an aligned supplier that delivers this same vision. With you are assured that as we have access to new technologies through our Tier 1 network providers.
