With 20 years of experience as a global SMS provider, Clickatell’s communication and engagement capabilities have been assisting business to stay in touch with their clients

“Karri is a global first and a brilliant solution that eliminates the inconvenience of school payments. Karri relies on its ability to communicate with parents. “Because SMS messages are delivered directly to their mobile phones, parents are able to navigate the download process and installation process with ease, and with a far higher success rate.” Clickatell’s APIs quickly and easily allowed us to “fire off an SMS from anywhere in our tech stack, making it very easy to develop it into applications.”

Louis Buys - Founder

“Alert-a-buddy is an automated buddy system that relies on SMS to help reduce workload, and provide a vital and robust employee safety net for lone workers around the clock, 365 days a year. As is the case for all SMS messaging customers, reliability is key. Clickatell’s “SMS messaging provides a quick and easy way for users to communicate with our system. Everyone is so familiar with SMS that it’s often the easiest way for them to communicate.”

Alanna Lawrie-Fussey - Managing Director

“Bands For Hire Ltd is a live music agency operating in the UK, providing musical bands for any occasion. They use SMS messaging to effectively communicate and inform clients that an email has been sent, prompting them to check their emails sooner. A simple SMS message takes care of the problem. Bands for Hire chose to use Clickatell for its “easy-to-use API with full and clear documentation and numerous code samples to get started.”
