Key benefits of RCS Messaging

Lower customer service costs

RCS messaging allows businesses to reduce pressure on in-house resources and lower customer service costs by providing more convenient tools for customers to access, including chatbots for common customer queries. This provides customers with a more engaging, personalised journey that  addresses their specific needs.

Enrich communication

Embed images, videos, and rich cards into messages. Better yet, use RCS Messaging for two-way customer conversation to support service interactions, payments and receipts, policy renewals, bookings/appointment reminders, FAQs and for a multitude of other customer touchpoints.

Access actionable engagement data

Access status-based read receipts for improved tracking. Real-time analytics provide you with insight about how customers are interacting with your messages and which communications are working best, helping you to improve  conversion rates, including ‘delivery’ and ‘seen’ reports.

Tap into expert professional services and support

Our Professional Services team supports our customers with everything from simple one-way RCS messages to more complex workflows and solutions.

Improve ROI

Stay agile and adapt your communication strategy as business and customer circumstances change. Automate and manage your business communication, analyse the results in real-time and make adjustments as you go to maximise campaign and business ROI. 

Gain ‘verified sender’ status to help reduce spam and reassure customers that interactions are from a trusted source.

What can RCS be used for?

Here are some of the ways you can have smarter interactions by sending richer content to your customers.


Retailers have to do all they can to maintain a competitive edge – and being able to send richer, mobile focused communications to their customers is going to be a big part of their future success.

RCS will play a big part in this, by delivering fully branded interactions directly to the customer’s default messaging application.

Example applications include:

  • Deliver digital receipts
  • Customer service chat interactions
  • Arrange/rearrange delivery times and delivery updates
  • Upsell or cross-sell products with carousels
  • Receive payments
  • Deliver marketing messaging.

Gain “verified sender” status to help to eradicate spam and reassure customers that interactions are not from fraudulent sources.

Set-up branded, automated interactions with customers, using tools like buttons and linked payment facilities – all of which help to promote self-service.

Example applications include:

  • Updating insurance claims (e.g. uploading photos and other details)
  • Making payments via linked facilities
  • Missed payment reminders with linked payment processing
  • Renewing policies
  • Applying for loans/credit
  • Fraudulent activity notification
  • Arranging in-branch appointments
  • Customer identity verification.

Many manual processes undertaken by utility providers can now be easily automated in a rich and intelligent way by using RCS.

This means that providers can expect to reduce the strain on their in-house resources, and also provide more convenient tools for customers to access services.

Example applications include:

  • Collect meter readings
  • Provide tariff selection facilities
  • Chat style customer service
  • Bill payments
  • Frequently asked questions.
Property & Estate agents

With RCS, agencies can add far richer content to their customer interactions. The net reults is that agents spend less time on the phone speaking with potential customers, which in turn frees them up to focus on other value add tasks.

Example applications include:

  • Rich property alerts including dynamic fields based on search criteria (including images, video, text, and maps)
  • Carousels with available properties making selections easier
  • Live chat with an agent without having to make a call
  • Booking and rearranging house viewings automatically
  • Document exchanges.

RCS supports enhanced engagement with patients, allowing them to perform many tasks independently, which would have previously required interaction with a healthcare representative.

Example applications include:

  • Booking and rearranging appointments automatically
  • Add appointments to calendar
  • Sending smart appointment reminders (i.e include images of healthcare professionals and practices)
  • Innoculation reminders (i.e. link to existing appointment management systems)
  • Send prescriptions
  • Supply test results.
Local Government

Local Governments have to carefully plan how to effectively engage with each of their audiences, to ensure all messages reach their destination.

RCS can help with this by increasing engagment levels, while at the same time reducing costs.

Example applications include:

  • Collect council tax or arrange repayment plans
  • General notifications
  • Maintenance engineer appointments booking and rearranging
  • Service closure notification
