RCS messaging 101: Your quick start guide

What is RCS messaging and how can businesses use it to its fullest potential? Read more about this messaging channel’s key features and functionalities, the different ways to use RCS, tips on choosing the right RCS provider and more.

Welcome to RCS, the evolution of SMS

Consumer preferences and demands are changing and we now all expect to receive richer and more interactive messages which is where RCS comes in. RCS, which stands for Rich Communication Services, offers a rich, immersive messaging experience similar to WhatsApp and Facebook Messenger. Send and receive not only texts but images, videos, voice recordings and location pins as well. 

Built on top of the existing SMS channel (so there’s no need to download a separate app), RCS is essentially seen by many as the next stage of the evolution of SMS. 

As long as your phone is RCS-enabled, you’ll be able to send and receive RCS messages. If not, your message will be converted to an SMS message. 

For businesses, this unlocks a world of possibilities. Provide customers with a rich messaging experience that they can access via their mobile’s built-in messaging app – helping you to enhance customer engagement and experience. You can also benefit from a branded business profile and brand verification, which boosts customer trust.

While it’s currently only available on Android devices, Apple has announced that it will adopt the RCS messaging standard in late 2024. So finally, iPhone and Android users can exchange rich messages and engage with interactive features like typing bubbles and read receipts without needing to download another app. All they need is an internet connection, whether that’s WiFi or mobile data.

5. Sales

From rearranging appointments to processing payments, handling common queries can be time-consuming and take resources away from the cases that really require human intervention. A chatbot delivered via RCS can not only solve this challenge, but also give customers the power to serve themselves, eliminating the need to speak to a support agent or experience delays in the process as a result of being put on hold.

Example applications include:

  • Appointment booking and management
  • Order updates
  • Account management
  • Answering FAQs

Case study: Southwark Council

Southwark Council wanted to capitalise on their success with SMS campaigns for those in early arrears on their council tax. With an existing campaign engagement rate of 32%,  Southwark planned to increase engagement levels and looked at RCS as an option because it provided the opportunity to build in suggested replies and calls to action that SMS alone could not provide.

By incorporating RCS into their communication strategy, Southwark Council saw:

  • A 55% increase in people choosing to make a payment, up from 21%.
  • A 60% increase in people choosing to engage with the customer service team for support.
  • 90% of people stating this was a better experience than SMS, in addition to making customers feel more reassured.

Choosing an RCS provider

Once you’re ready to implement RCS into your business communication strategy, your next step is to choose the right provider. Here are some areas to consider.

Highly experienced

Has your RCS provider worked with businesses like yours? This could be in terms of project scope, business size or they’ve worked with organisations in the same industry as you. The best providers will also be experienced in implementing mobile messaging solutions as a whole so they can help you to decide where it’s best to use RCS in addition to your existing comms channels for maximum ROI.

At Esendex, we’ve been helping our customers benefit from mobile-focused communication strategies for over 20 years. We’re also committed to learning about and investing in future developments in business messaging so you don’t have to. That means we can help you stay one step ahead of the competition.

Customer-centric approach

Can your RCS provider respond proactively when your business needs change? This may mean implementing RCS in a way that’s best for your organisation or recommending a different messaging approach that might be better suited.

For example, Esendex will take the time to understand your business, from challenges to goals, so we can help you select the right mobile messaging solution for your needs. That includes bespoke solutions and integrations.

RCS feature set 

Some key RCS features include high-quality media sharing, interactive buttons, read receipts and message performance reports. What features can your prospective RCS provider offer?

The Esendex messaging studio platform is included as part of our RCS offering. So in addition to features like branded business profiles, access to suggested replies, interactive buttons, images and other media, you can also:


Can your RCS provider support interoperability across different types of devices and operating systems? This means your RCS messages can be sent and received by a wide range of users.

Esendex will first identify whether the recipient’s device can receive RCS messages. If the device is RCS-compliant, the rich message will be delivered directly into the default messaging app on the recipient’s phone – just like a standard SMS.

If the device isn’t RCS-compliant, the recipient will receive an SMS landing page message so they still receive the rich experience you intended.

Integration capabilities

The ability to integrate with your existing systems, such as your CRM solution or any other messaging platforms, is key to a smooth RCS implementation. What seamless integration solutions or APIs does your provider offer? 

Enabling business messaging is quick and easy with Esendex. Our Rich Content API allows you to integrate message sending capabilities into your existing systems. So within minutes, you can start sending RCS messages.

Level of support

As your business grows, your messaging requirements may do so too. Can your RCS provider scale its services and support to align with your changing needs? 

At Esendex, we’re committed to maintaining strong customer relationships. That’s why we offer 24/7 support to every customer. No tiered pricing, no hidden costs. We strive to be the expert partner you can rely on.
