Clickatell, a global communication technology organization with a remarkable 20-year history, has become a pioneer in the field of SMS API services. Its SMS gateway now boasts a reach of over 6 billion people worldwide, making it a dominant player in the industry. Through its wide range of communication solutions, Clickatell empowers businesses, institutions, and governments to connect easily with clients, employees, and partners through the most popular messaging channels, thus enhancing customer experiences and helping ensure effective communication.

Avenga has been Clickatell’s technical partner for 7 years, working on several groundbreaking projects. We’ve been instrumental in delivering timely resources and assistance to Clickatell, helping them design, deliver, deploy, and maintain many of their world-renowned innovative products and services. One of the most notable projects we’ve cooperated with is Clickatell’s enterprise messaging platform.

Businesses and institutions face a significant challenge in communicating with people across various mobile networks in a secure and instant manner. SMS, with its impressive 98% open rate, is one of the most highly effective tools for enhancing customer engagement and loyalty. It is versatile and can be used for various services like 2FA authentication, transactional notifications, and marketing campaigns.

However, establishing connections with different mobile networks individually in multiple countries is impractical and not cost-efficient. Also, creating and managing large contact lists for each SMS campaign compounds the issue further. To address these challenges, Clickatell decided to develop an innovative SMS-enabling platform that allows two-way text message interaction with any communication solution used by businesses. The company has partnered with Avenga to ensure the proper execution of this project.


Architectural design and implementation

Engineered a comprehensive communication platform that offers businesses access to the world's largest SMS gateway. This system sends messages securely and promptly, reaching over 6 billion people worldwide.

Intuitive UI

Designed a straightforward interface that allows businesses to create single admin accounts, which can be accessed and managed by multiple users based on their assigned roles, rights, and permissions.

Advanced functionality

The Clickatell platform enables both one-way and two-way messaging. For urgent alerts and pin-numbers, businesses can use the first option to enhance internal business processes by sending time-sensitive texts. To improve lead generation, conduct SMS surveys, and provide better overall support, businesses can use the second option.


The solution is highly flexible in terms of integration, enabling businesses to apply the Clickatell platform's features to any communication system they may have, whether it's an app or a website.


The platform offers extensive configuration functionality that enables deeply personalized correspondence between businesses and clients.
