The right messaging solutions for your business


Payments & Collections

Ethical debt collection has never been more important; to stay afloat, companies need to get paid, but many customers are vulnerable and need an individual approach. Our award winning Mobile Collections platform helps you strike the right balance.


Omnichannel Customer Service

Customers want to communicate with brands on their preferred channels: WhatsApp, SMS, RCS. And brands want to be able to manage all of their customer interactions in one place. Our omnichannel chat platform can help.


Customer Satisfaction

Customer feedback is essential to ensuring that you retain customers and develop your products / services in a way that builds loyalty to your business. Mobile-first strategies solicit significantly more feedback – helping you make better decisions.


Customer Notifications & Reminders

You can reduce the cost of missed appointments, increase customer loyalty, and lower your service costs by implementing a mobile-first customer notification programme. Options range from simple but effective SMS to two-way rich communication.


Internal Communications

From taking the effort and expense out of staff rostering, to measuring employee engagement, a mobile-first approach to internal communication delivers greater response rates than email or phone calls.


Software Partners / Integrations

The easiest way to build mobile messaging into your communication strategy is to integrate our services with your existing software applications. We specialise in connecting with legacy software platforms and have over 1,000 existing API integrations.

Customer Reviews

I’ve worked with Esendex in the last 3 companies I’ve been employed in. Each company had different requirements and set ups and Esendex were able to accommodate their needs in all three.

Always get a prompt response from the team. Always willing to help. The platforms are very user friendly.


Esendex are a brilliant company to work with. We have utilised their services for over 6 years. Within this time they have been more than helpful. They have recently developed a bespoke mobile journey for our contractors to use.

Esendex and the team are an invaluable resource to our company. We would not have any hesitations recommending them.


Used Esendex now for about 6 years and they have always given my company excellent service, may it always continue.

I have recommended to at least 10 companies and some have taken up and continue to use the service.
