Insider One RCS: Transform SMS into Rich, Actionable, and Interactive Experiences

What is RCS (Rich Communication Services)?

RCS (Rich Communication Services) is the next evolution of mobile messaging that upgrades traditional SMS into a richer, more app-like experience inside a customer’s native messaging app. For brands, RCS supports rich media (like high-resolution images and video) and interactive UI elements (like carousels and buttons), which enable more engaging customer experiences than text-only messages.

Why enterprise brands are investing in RCS now

RCS has been around for years, but the context has shifted dramatically. With over 1 billion Android users already sending billions of RCS messages daily and Apple’s iOS 18 support turning it into a true cross-platform standard, rich messaging is evolving from “nice to have” to a “default expectation” for mobile conversations.

A recent study by global tech strategists Juniper Research forecasts that operators will generate $3.1 billion globally from RCS for Business traffic in 2027, up from $1.2 billion in 2025.

Enterprise brands are investing now because RCS combines the universal reach of phone-based messaging with visual, interactive capabilities,  like rich cards/carousels, documents, CTAs, quick replies, and branded verification. This is even more critical because it doesn’t need opt-in permission and creates an app-like experience without needing the user to install the app. 

This powers higher engagement in critical moments, from ecommerce promotions and cart recoveries to travel service updates and banking alerts.

How RCS compares to SMS and MMS

SMS is reliable and universal, but it’s fundamentally constrained: it’s primarily text-based and typically lacks built-in interactivity and native rich content presentation. RCS changes the experience by enabling rich media, buttons, and structured message formats like carousels, so recipients can act directly from the message thread. 

If you need maximum reach with basic content, SMS remains the baseline. If you need richer visuals and structured interactivity in the native messaging app experience, RCS is built for that, especially with carousels, suggested actions/replies, and branded/verified sender experiences.

Components of an RCS message

Brand Logo

Displays your company logo prominently in the sender profile or message header, reinforcing visual brand recognition.

Brand Description

A short text field (often in the conversation start card) that describes your business, appearing next to the logo for context.

Verified Sender

A checkmark or badge confirming the message is from an authenticated business, building trust and reducing scam perceptions.

Media – Rich cards 

Supports high-res images, videos, GIFs, PDFs, or audio previews directly in the message for engaging, visual storytelling. Carousels (rich card carousels) let you present multiple items, such as products, destinations, or options, in a single message. This is especially useful when a customer needs to compare or choose without bouncing across multiple pages.

Title Text

Bold, prominent header (up to ~200 characters) that grabs attention and summarizes the message’s purpose. Also helps create an app-like experience in the message center. 

Descriptive Text

Supporting body copy (up to 2048 chars in rich formats) providing details, context, or instructions below the title.

Suggested Actions 

Clickable buttons for one-tap tasks like “View Map,” “Call Now,” “Add to Calendar,” or “Open URL,” streamlining user journeys.

Suggested Replies

Pre-defined quick-response chips (e.g., “Yes,” “No,” “Track Order”) that users tap to reply instantly, guiding conversations.

Types of RCS messages 

Basic RCS 

Basic RCS serves promotional and transactional use cases like OTPs, alerts, limited-time offers, or event announcements. They are limited to 160 characters with text, URL previews, emojis, and special characters; these messages display from a verified sender with delivery/read status. For non-RCS devices, they fallback to SMS automatically. The sender can also see the status of messages sent and whether the message has been delivered or read.

Single RCS 

Single RCS is a powerful way for brands to connect with customers by sending multimedia like carousels and rich cards. Effective for prompting quick responses by displaying personalized content like product visuals or special offers. These messages can also help direct users to take specific actions, such as scheduling events, locating stores, calling support, or visiting a website.

Conversational RCS 

Conversational RCS enables real-time, two-way dialogue between brands and customers, supporting rich media (images, videos, audio, PDFs, carousels) alongside interactivity like quick replies and branching logic during an active session (typically 24 hours). 

It comes in two types: brand-initiated (A2P), where businesses start with a rich message that can escalate to chat upon reply; and user-initiated (P2A), where customers message first for support or inquiries. This format embeds full customer journeys, from marketing and ordering to after-sales, in one thread. It is ideal for use cases like support, guided shopping, surveys, or upsells.

Real-world use cases 

RCS is best used where visuals, trust, and immediate action matter, especially for high-intent moments and service journeys.

Ecommerce: recommendation carousel with “View product” CTAs

Use an RCS carousel to showcase multiple recommended items with high-res images, then add a CTA like “View Product” to send users directly to the product page. This format aligns with RCS support for interactive carousels and action buttons.

Travel & hospitality: disruptions resolved inside the message

For flight delays or changes, RCS suggested actions can present clear next steps (e.g., rebook or contact support) without forcing customers to search a help center or stand in line. RCS suggested actions and replies are explicitly designed for these kinds of guided flows.

Banking: trusted, verified communication for high-risk moments

When fraud or suspicious activity occurs, a verified brand profile (logo + verification badge) helps customers quickly recognize legitimate outreach and reduce spoofing risk. Insider One’s RCS supports branded messaging elements like logo and verification badge for this trust-focused use case.

Where RCS fits in Insider One’s platform ecosystem

Insider One’s RCS integrates seamlessly as a new messaging channel right alongside SMS and MMS, empowering teams to expand mobile programs without rebuilding workflows, custom setups, or data pipelines.

Leveraging the drag-and-drop interface customers already love, RCS slots into the familiar SMS flow: select it as the message type during campaign design, preview rich elements in real-time, and test/send with one click. No new integrations or steep learning curves, and setup takes just minutes.

From there, RCS powers full customer journey orchestration: trigger messages based on real-time events (e.g., cart abandonment, flight delays), layer in unified customer data for personalization, build segments across channels, and automate follow-ups blending RCS with email, push, in-app, and web experiences. Analytics flow into the same dashboard for CTR, open rates, and revenue attribution.

This unified approach keeps RCS as a high-engagement lever in omnichannel strategies, scaling effortlessly as brands adopt richer mobile tactics.

Open-rate tracking (beyond delivery)

Unlike traditional SMS, RCS can support engagement signals such as opens/read receipts, depending on implementation, enabling better measurement of message performance. Insider One’s RCS capability includes open-rate tracking for RCS messages.
