Esendex and its multichannel messaging platform

Esendex is a UK-based provider of business messaging services, trading as Commify UK Limited. The company presents itself as a CPaaS (Communications Platform as a Service) provider and states that it has been supplying business messaging for more than 20 years. Its offer centres on a single platform and build-once APIs that let organisations send, manage and track messages across several channels.

The company reports more than 46,000 business customers worldwide and says it is part of the Commify group, which it describes as having made 18 acquisitions since 2003, with more than 45,000 customers and responsibility for sending over five billion messages a year.

Channels available through the platform

The messaging stack covers the following channels:

• SMS: sending and receiving text messages to any country at scale.
• WhatsApp: interactive, conversational messaging powered by Esendex APIs.
• RCS: rich media messaging intended to make messages stand out.
• Email: sending, receiving and tracking emails while managing communication channels securely.
• Voice: intelligent IVR and IVM voice solutions aimed at call centre productivity.
• Online Journeys: consistent branded journeys from the first message onwards.

Platform, APIs and reseller programme

Esendex structures its products around three main routes. The Messaging Platform is a single place to send, manage and track messages across every channel. The API route is aimed at developers and businesses integrating multichannel messaging into their own systems, with documentation covering SMS, WhatsApp, RCS, email, voice and multichannel APIs. A reseller programme allows partners to add multichannel messaging to their own offer, set their own pricing and generate a new revenue stream. The company also offers a Managed Services team that builds bespoke packages.

For developers, Esendex provides a Developer Hub with documentation and a seven-day free trial with no commitment.

Use cases and industries served

The site groups its applications into several use cases: customer service, notifications and reminders, two-way conversational messaging, authentication and security through one-time passwords (OTP), marketing, customer research and critical alerts. These cover appointment reminders, confirmations, delays, order updates, interactive polls, buttons, suggested replies, pictures, videos and links, as well as automated welcome or away messages and emergency communications.

Esendex was founded by Adam Bird and Julian Hucker in 2001 in Nottingham, where its headquarters remains.
