RCS Rich Cards vs Carousels: Understanding the Difference

Rich Communication Services, better known as RCS, has quietly become one of the most important upgrades to business messaging since SMS itself. For brands trying to reach customers directly on their phones, RCS opens the door to a far more visual, interactive experience than plain text ever could. But once a business decides to adopt RCS, a practical question comes up almost immediately: should you use a rich card or a carousel? The two formats look similar at first glance, but they serve different purposes, and choosing the wrong one can quietly undercut your campaign’s performance.

This guide breaks down what rich cards and carousels actually are, how they differ structurally and strategically, and how to decide which one fits a given use case — whether you are sending order updates, running a promotional campaign, or building a full conversational commerce flow.

What Is RCS, and Why Does the Format Matter?

RCS is the modern successor to SMS, built into the default messaging apps on most Android devices and increasingly supported across iOS as well. Unlike SMS, which is limited to 160 characters of plain text, RCS supports images, buttons, typing indicators, read receipts, and structured layouts. For businesses, this means a single message can now look and feel like a mini web page rather than a wall of text.

Within RCS Business Messaging, Google and the GSMA defined a set of structured message types that brands can use to present information. Two of the most commonly used are rich cards and carousels. Both let you combine an image, a headline, descriptive text, and action buttons into a single message. The difference lies in how many of these “cards” appear, and how the recipient interacts with them.

What Is an RCS Rich Card?

A rich card is a single, self-contained message unit. It typically includes:

A hero image or video thumbnail at the top
A title and short description
Up to two or three action buttons (for example, “Buy Now,” “Learn More,” or “Call Us”)

Rich cards come in two orientations: vertical, where the image sits above the text, and horizontal, where the image sits beside the text. This flexibility makes rich cards well suited to situations where you want to focus the recipient’s attention on one specific piece of information — a single product, a single offer, or a single update.

Because a rich card presents only one message and one call to action, it tends to feel focused and intentional. There’s no scrolling required, no competing options to weigh. The recipient sees the card, reads the message, and either taps a button or moves on. This makes rich cards particularly effective for:

Order confirmations and shipping updates
Appointment reminders
Single-product promotions
Account alerts that require one clear action

What Is an RCS Carousel?

A carousel is essentially a horizontally scrollable sequence of rich cards, all delivered within a single message. Instead of showing one product, offer, or update, a carousel can present anywhere from two to ten cards that the recipient swipes through.

Each card in a carousel functions independently, with its own image, headline, description, and buttons. This makes carousels ideal for scenarios where you want to give the customer a choice, showcase a range of items, or tell a sequential story across several images. Common use cases include:

Showcasing multiple products in a new collection
Presenting several flight, hotel, or travel options
Comparing plan tiers or subscription packages
Walking a customer through a multi-step process, such as onboarding

Carousels essentially bring a “browse and choose” experience to messaging, something that was previously only possible on a website or app. For an e-commerce brand launching a new seasonal line, a carousel lets the customer flip through several products without leaving the conversation thread, tap the one they like, and move straight into a purchase flow.

Key Structural Differences

At a technical level, the difference between a rich card and a carousel comes down to cardinality and layout intent.

Number of cards: A rich card is always a single unit. A carousel is a container of multiple rich cards, typically between two and ten, depending on the messaging platform’s limits.

Navigation: Rich cards require no navigation since there is only one thing to view. Carousels require the user to swipe horizontally, which introduces a small amount of friction but also invites exploration.

Message size and load time: Because carousels contain multiple images and multiple sets of text, they are heavier messages. This can matter on slower connections, and it also means more content needs to be prepared and quality-checked before sending.

Attention distribution: With a rich card, one hundred percent of the recipient’s attention goes to a single offer or update. With a carousel, attention is split across several cards, and there’s a real possibility the recipient stops scrolling before reaching your best offer or highest-margin product.

Choosing Between a Rich Card and a Carousel

The decision usually comes down to the goal of the message and the nature of the content.

Use a rich card when:

You have one clear message and one clear action you want the recipient to take
The message is transactional in nature, such as a delivery update or payment confirmation
You want to minimize decision fatigue and drive a fast, direct response
You’re working with limited content or a single hero product

Use a carousel when:

You want to present a range of products, plans, or options
The customer benefits from comparing items side by side
You’re telling a story or walking through multiple steps
Your campaign goal is discovery and browsing rather than a single conversion point

A useful mental model is to think of a rich card as a highly targeted advertisement and a carousel as a small storefront window. If you know exactly what your customer wants, a rich card gets them there faster. If you want to inspire consideration or showcase variety, a carousel does more of the work.

Design Best Practices for Both Formats

Regardless of which format you choose, a few best practices consistently improve performance.

Lead with a strong image. RCS is a visual channel, and the image is often what determines whether a recipient engages further. Use high-resolution, well-lit images that clearly represent the product or offer, and avoid cluttered graphics that don’t render well on small screens.

Keep copy concise. Rich cards and carousel cards have limited space for text. Write headlines that immediately communicate value, and use description fields to add just enough context to support a decision, not to explain everything.

Prioritize your best card first in a carousel. Since not every recipient will scroll through all the cards, put your strongest offer, most popular product, or clearest value proposition in the first position.

Limit buttons to essential actions. Every rich card supports a small number of buttons. Rather than listing every possible action, choose the one or two that actually move the customer forward, such as “Shop Now” or “Track Order.”

Test load performance. Carousels in particular can be heavier to load. Compress images appropriately so the message renders quickly, since delays reduce engagement.

Personalize where possible. Whether you’re sending a single rich card confirming a purchase or a carousel showcasing recommended products, personalization based on customer data significantly increases relevance and response rates.

How Rich Cards and Carousels Fit Into a Broader Messaging Strategy

Neither format exists in isolation. Most mature RCS strategies use both, deployed at different stages of the customer journey. A retail brand, for example, might use a carousel to introduce a new product line to a segment of engaged subscribers, then follow up with individual rich cards for order confirmation, shipping updates, and delivery notifications once a purchase is made.

This combination allows a business to guide the customer through discovery, decision, and post-purchase support entirely within the messaging channel, all while maintaining the rich, branded visual experience that RCS makes possible. Compared to SMS, where every step of this journey would be a plain text message with a link, RCS rich cards and carousels let brands keep customers inside a native, trusted, and visually engaging experience from first contact through fulfillment.

Measuring What Works

Because RCS supports read receipts and interaction tracking, businesses can measure engagement at a granular level: delivery rate, read rate, button tap rate, and conversion rate per card. When testing rich cards against carousels for a given use case, it’s worth tracking not just overall conversion but also how far into a carousel recipients typically scroll before tapping or dropping off. This data often reveals whether a single, focused rich card would actually outperform a carousel for that particular campaign, or whether the variety on offer in a carousel is genuinely driving incremental engagement.

Final Thoughts

Rich cards and carousels are two of the most powerful tools available in RCS Business Messaging, but they are built for different jobs. A rich card delivers focus and clarity, ideal for transactional messages and single-offer promotions. A carousel delivers breadth and choice, ideal for product discovery and multi-option decisions. The businesses that get the most value out of RCS are the ones that match the format to the intent of each message rather than defaulting to one format across every use case.

As RCS adoption continues to grow across both Android and iOS, understanding these formats — and using them deliberately — will increasingly separate messaging campaigns that convert from those that simply get ignored.
