What is rich messaging?

Rich messaging aims to support person-to-person or business-to-person communication with upgraded, interactive messages. Senders can attach high-resolution photos, videos, audio messages, GIFs, and an array of other media to enhance the receiver’s experience while conveying a lot more information with each message.

Google’s Rich Communication Services (RCS), for example, is one approach to rich messaging, but it is not the same thing as rich messaging in general.

For a number of reasons, rich messaging applications have supplanted SMS in both personal and professional outreach. SMS messages simply do not support many staples of modern communication, such as group chats or “read” receipts. What’s more, the reach of SMS will remain limited because it requires a cellular connection, whereas rich messages can be sent over the internet.

Though SMS will probably be around for a while, rich messaging is becoming increasingly popular as companies have been trending toward greater use of applications like WhatsApp.

With RCS, businesses don’t need a separate app —modern features like typing indicators, read receipts, and media sharing are available directly in the phone’s native messaging app (Google Messages, Apple Messages). This allows CX leaders to deliver rich, branded, and secure experiences tied to a customer’s mobile number without forcing app downloads.

Armed with these and similar channels, CX directors can now:

• More easily capture new customers with compelling outreach.
• Resolve customer issues directly via text, chat, or social media messaging (a huge advantage given how obsessed we’ve all become with our phones);
• Interact with customers in real-time, which is a capability more and more people are looking for when seeking help.
• Gather and act on analytics.
• Scale their communications while simultaneously reducing the burden on contact center agents.

Given these facts, it’s no surprise that more and more CX leaders are making texting a key component of building lasting customer relationships.

How does RCS messaging work?

RCS messaging lets users send messages over mobile data or WiFi through a supported native messaging app. Instead of requiring both people to install the same third party app, RCS uses a phone number as the user’s identity and works across compatible carriers, devices, and messaging services.

The technology is based on the RCS Universal Profile, a GSMA specification that defines how RCS services should work across networks and devices. Before starting RCS chats, a messaging service can check whether the recipient supports RCS and which RCS features their device can receive.

When RCS is available, conversations can include high resolution media, read receipts, typing indicators, and interactive elements such as suggested replies. For business messaging, an RCS agent can also send branded messages containing rich cards, media, suggested actions, and other interactive content.

If RCS is unavailable for a particular customer, businesses can use SMS or MMS as a fallback rather than losing the message entirely if there is no internet connectivity. The result is an RCS messaging experience that adds many of the features people associate with messaging apps while keeping conversations inside the phone’s regular messaging inbox.

RCS vs RCS for Business

RCS and RCS business messaging use the same underlying technology, but they serve different purposes. Standard RCS is designed mainly for person to person mobile messaging, while RCS for Business gives companies additional tools for branded customer communication.

With standard RCS, users can send richer messages through a supported native messaging app. Depending on the device and carrier, RCS features can include read receipts, typing indicators, group conversations, and high quality media. On supported Android devices, users can usually turn on RCS through their messaging settings and tap RCS chats to manage related options.

RCS business messaging extends the same RCS network for communication between companies and customers. Businesses can create verified sender profiles, add branding, send rich cards, offer suggested replies, and include actions customers can tap directly inside a conversation.

The main difference is therefore who is sending the message and what the messaging experience supports. Standard RCS improves everyday conversations between people. RCS for Business adds business identity, interactive customer experiences, and tools designed for customer service and outbound communication.

What is rich messaging on different platforms?

Now that you have more perspective on what rich messaging is and what it offers, let’s spend some time talking about which platforms you should focus on.

There are a few major providers of rich messaging, but we’ll focus on Apple and WhatsApp. Apple has long been a communication giant, but with billions of users worldwide, Meta’s WhatsApp has certainly earned its spot at the table.

The sections below provide more details about how rich messaging works on each platform.

What is Rich Messaging on Apple?

Through Apple Messages for Business, contact centers can offer their customers a direct line of communication. This allows for far greater speed and convenience, to say nothing of the personalization opportunities opened up by artificial intelligence (more on this shortly).

What is RCS on iPhone?

Apple added support for RCS messaging with iOS 18, giving iPhone users a richer way to communicate with people who are not using iMessage. RCS conversations can include high resolution photos and videos, delivery receipts, read receipts, and typing indicators. They still appear as green message bubbles in Apple’s Messages app.

To use RCS on an iPhone, the device needs iOS 18 or later and a cellular plan from a carrier that supports RCS. Availability therefore varies by carrier and region. Users can manage RCS through Settings, Apps, Messages, and RCS Messaging.

Apple also supports RCS business messaging, allowing supported businesses to send alerts and transactional updates through the Messages app. Users can turn RCS Business Messages on or off separately in their messaging settings.

Security has also improved. Starting with iOS 26.5, Apple began rolling out end to end encrypted RCS messaging in beta with supported carriers. Encrypted conversations display a lock icon so users can see when that protection is active.

What is Rich Messaging on WhatsApp?

WhatsApp is a widely used application that uses rich messaging for texts, voice messages, and video calling for over two billion users worldwide. Utilizing a simple internet connection for its services, WhatsApp allows users to bypass the traditional costs associated with global communication, making it a cost-effective choice.

It supports integration with tools like the Quiq agentic AI platform, which can automatically transcribe voice messages and allows for the export of these conversations for analysis using technologies like natural language processing.

What is RCS on Google Messages?

Google Messages is one of the main ways Android users access RCS. When RCS chats are enabled, users can send messages over mobile data or WiFi while gaining features such as read receipts, typing indicators, group chat controls, and high resolution photo and video sharing.

Google Messages also supports RCS conversations with businesses. Verified companies can appear with their name, logo, and verification checkmark, then send interactive content such as images, suggested replies, and action buttons directly inside the conversation. Customers can use these experiences for tasks such as getting support or tracking an order without moving to another app.

RCS availability still depends on the device, carrier, and region. If RCS cannot be used, Google Messages can fall back to SMS or MMS depending on the user’s settings and connection.

RCS vs. SMS vs. MMS vs. OTT: Understanding the Key Differences in Messaging

As consumer expectations have grown, so has the need for messaging technology to evolve. Businesses can no longer rely solely on traditional SMS to deliver standout experiences, especially when customers are used to rich, app-like interactions. That’s where understanding the differences between messaging types comes in.

From basic texts to interactive messages with buttons, images, and videos, here’s how SMS, MMS, RCS, and OTT messaging stack up.

What is SMS?

SMS (Short Message Service) is the most basic form of text messaging. It has a 160-character limit and doesn’t support media like images or videos. Despite its simplicity, it’s still widely used for short, timely notifications and reminders.

What is MMS?

MMS (Multimedia Messaging Service) expands on SMS by allowing users to send pictures, videos, and audio. It relies on mobile data and carrier support, and can be more expensive to send—especially at scale.

For businesses that still rely on SMS and MMS for large-scale outreach, platforms like Textedly provide dedicated solutions for sending bulk SMS and multimedia messages, managing opt-ins, and tracking campaign performance. While MMS doesn’t offer the full interactivity of RCS or OTT messaging, it remains a dependable and widely supported option for appointment reminders, alerts, and promotional campaigns.

What is RCS?

RCS (Rich Communication Services) takes messaging to the next level with features like read receipts, typing indicators, carousels, high-resolution media, interactive buttons, and branded customer experiences via verified RCS Agents. It’s carrier-dependent and still gaining traction, but it offers a powerful upgrade for business-to-customer communication while running over Wi-Fi or data networks instead of the cellular voice network

What is OTT Messaging?

OTT (Over-the-Top) messaging apps like WhatsApp, Facebook Messenger, and Apple’s iMessage work over the internet and bypass traditional carriers altogether. These platforms offer end-to-end encryption, rich media, and global reach, making them a go-to for brands looking to meet customers where they are.

RCS also enables businesses to create branded, interactive customer journeys. Features like carousels, surveys, order updates, and suggested reply buttons allow for more engaging experiences while increasing trust with verified sender IDs.

Key Features and Benefits of Rich Messages

Whether on Apple, WhatsApp, or another channel, rich messaging is one of the best ways of interacting with customers; it’s convenient and powerful enough to help a CX leader rise above their competition.

At its core, rich messaging is defined by key features such as high-resolution photos and videos, read receipts, typing indicators, branded buttons, quick reply options, and interactive carousels, all within the customer’s native messaging app. These features create smoother, faster, and more trusted interactions compared to traditional SMS or MMS.

Below, we will get into more specifics about the advantages to be had from using rich messaging.

1. Cost-Effectiveness

Because it works over the internet, rich messaging is a great way for CX directors to connect with customers without breaking the bank.

But it can also help your organization save money by reducing customer support costs. When consumers need to talk to someone at your business, they can speak to knowledgeable agents (or a large language model trained on those agents’ output) through your rich messaging platform.

In this same vein, rich messaging makes it far easier to engage in asynchronous communications. This means agents are able to handle multiple conversations at the same time, resulting in further savings.

Finally, rich messaging is far more scalable than almost any other approach to customer outreach, especially when you effectively leverage AI.

2. Real-Time Insights

When they integrate rich messaging with a platform offering excellent support for real-time analytics, companies gain access to conversation analytics that provide the insights they need to improve contact center performance.

They can generate reports on click rates and other helpful interaction metrics, for instance, giving CX leaders a feedback loop they can use to test changes and see what improves customer satisfaction, loyalty, and lifetime value.

3. Rich Messaging is Native to the Devices Customers are Already Using

You could pay for the most compelling billboard in the history of marketing, but if it’s on the moon where no one will see it, it’s not going to do you much good. For this reason, we’ve long pointed out that it’s important to meet your customers where they are – and these days, they’re on their phones.

When combined with the statistics in the following section, we think that the case for rich messaging as a central pillar in the CX director’s communications strategy is very strong.

4. Increased engagement through RCS chats

As it turns out, text messaging consistently achieves higher open and response rates compared to other methods. Adding elements like tappable carousels, suggested replies, and rich media further boosts engagement by making every message interactive and visually compelling.

This high level of engagement demonstrates the significant potential of text messaging as a communication strategy. Considering that only about 25% of emails are opened and read, it becomes clear that investing in text messaging as a primary communication channel is a wise decision for effectively reaching and engaging customers.

5. The human touch (but with AI!)

Rich messaging lets brands personalize conversations at scale with the help of AI. Machine learning powers this personalization, the same tech behind Netflix recommendations. Now, thanks to advancements in agentic AI, this same technology is being integrated into text messaging.

Previously, language models lacked the necessary flexibility for personalized customer interactions, often sounding mechanical and inauthentic. However, today’s models have greatly enhanced agents’ abilities to adapt their conversations to fit specific contexts. While these models haven’t replaced the unique qualities of human interaction, they mark a significant improvement for CX directors aiming to improve the customer experience, keep customers loyal, and boost their lifetime value. What’s more, when used over time, these innovations will help a CX leader stand out in a crowded marketplace while making better decisions.

To make use of this, though, it helps to partner with a platform that offers this functionality out of the box.

6. Security

RCS security depends on the type of conversation. Consumer RCS now supports end to end encryption across supported iPhone and Android devices, with Apple beginning its rollout in iOS 26.5 and Google Messages supporting the same cross platform standard. Users can see when encryption is active through a lock icon in the conversation.

RCS for Business works differently. Business messages are encrypted while traveling between the customer, Google, and the messaging provider, and stored messages on Google servers are encrypted as well. However, RCS for Business does not currently provide end to end encryption because Google needs access to message content for spam, phishing, and malware protection.

Businesses should therefore treat RCS as a secure messaging channel while still considering their own privacy obligations and the sensitivity of the information they ask customers to share.

How much does RCS messaging cost?

There is no single price for RCS messaging. Costs depend on the country, carrier, provider, message type, and whether a business is charged for individual messages or conversations. This is similar to popular messaging apps used for business communication, where pricing can vary based on how and where messages are delivered.

For traffic outside the US, Google supports different billing models for conversational and nonconversational RCS agents. Some interactions are billed per message, while conversational agents can be charged for a 24 hour conversation window that allows multiple messages between the customer and business. In the US, carriers set their own rates and messages can be classified differently depending on whether they contain text, rich media, or interactive content.

The messaging provider you use can add its own charges as well. For example, Twilio currently lists US RCS text messaging from $0.0083 per inbound or outbound message, while rich media messages cost more. Carrier fees and onboarding charges may also apply.

Businesses considering implementing RCS should therefore calculate costs based on message volume, customer location, expected message types, and provider pricing. Since RCS works directly on supported mobile phones, companies can leverage RCS without asking customers to download another app, which can make the additional messaging cost worthwhile for customer service and other business conversations.

How businesses get started with RCS

Implementing RCS requires more setup than sending traditional SMS messages, since businesses need an approved RCS agent and a provider that can connect them to supported carriers. Once that foundation is in place, RCS delivers a much richer customer experience through an advanced messaging protocol built for branded conversations and high quality media sharing.

1. Choose an RCS provider

Businesses typically start by choosing a messaging provider or customer communication platform that supports RCS for Business. The provider handles much of the technical connection between the company, Google, and participating mobile networks.

2. Create your RCS agent

An RCS agent represents the business inside the customer’s messaging app. Companies provide details such as their business name, logo, contact information, website, and other brand information that customers can use to identify the sender.

3. Complete business verification

Before an agent can communicate with customers at scale, the business needs to complete the required verification and approval process. Verification helps customers distinguish legitimate companies from unknown senders and gives the business a recognizable identity inside RCS conversations.

4. Build and test the messaging experience

Businesses can then create the actual customer journeys they want to offer through RCS. This could include customer support conversations, appointment reminders, order information, product recommendations, or campaigns containing high quality media sharing and interactive responses.

Testing is especially important because RCS capabilities can vary between devices, carriers, and markets. Businesses should also decide when SMS messages will be used as a fallback if RCS is unavailable for a recipient.

5. Launch and connect RCS with your existing channels

Once the agent has been tested and approved, it can be launched on supported networks. RCS can then sit alongside existing channels such as SMS, WhatsApp, Apple Messages, and web messaging rather than operating as an isolated communication channel.

Platforms such as Quiq can bring these conversations together, allowing businesses to add RCS while keeping customer interactions connected across the channels they already support. Essentially, you can create a cross-carrier messaging initiative without doing any heavy lifting.

Bring RCS conversations into Quiq

RCS gives businesses a richer way to reach customers without asking them to download another messaging app. But adding the channel is only part of the job. Companies also need a way to manage those conversations alongside the other channels their customers already use.

Quiq supports Google RCS alongside SMS, Apple Messages, WhatsApp, web chat, and other messaging channels. Businesses can use rich elements such as images, video, and interactive replies while managing customer conversations through the same conversational platform.

Quiq can also help businesses through the Google RCS registration process, making it easier to add RCS to an existing customer communication strategy rather than treating it as a separate system.
