SMS via Esendex API


London, UK



Houseful, formerly known as Zoopla, has been using SMS across its various brands for several years. They decided to consolidate their business messaging capability, to secure economies of scale while supporting agents and partners to deliver a consistent quality customer experience. 

We’re always aiming to improve deliverability when it comes to SMS and the Esendex API has helped us achieve this for everyone who touches Houseful’s Estate Agent CRM ecosystem. In partnership with Esendex, we’ve consolidated our SMS service across Estate Agent CRM products to reduce costs and provide technology that will get smarter as business communication technology evolves.

Challenge & Key Obstacles

Houseful had been using SMS across the group with different suppliers supporting different parts of the business. In 2010, Houseful’s cloud-based property software Jupix joined the Esendex platform and was subsequently followed by Expert Agent in 2019.

The group selected Esendex as its sole supplier in 2023, when its flagship Estate Agent CRM, Alto, also moved to Esendex. The Group chose the Esendex API as it was quick to integrate across its existing group platforms and processes and could be added to over time. Another important consideration was that the system needed to handle varying SMS volumes – ranging from thousands to millions – with the same system reliability and competitive send rates as a given.

As a frontrunner in the technology space, Houseful also wanted to identify an SMS provider that would innovate and support them as mobile and cloud-based communication evolved.

Our estate agent customers need to send appointment reminders and property transaction updates reliably and on time. With SMS from Esendex, texts land straight into the hands of the agent’s clients when they are most valuable to them.
