How to Improve Customer Engagement with Business SMS: How RCS Rich Cards Work vs. Alternative Technologies

Customer engagement has become the cornerstone of modern business growth. As brands compete for attention in an increasingly crowded digital landscape, the messaging channel you choose can make or break your outreach strategy. While traditional SMS has long been the workhorse of business communication, a new generation of messaging technology — RCS (Rich Communication Services) — is rapidly redefining what's possible. Central to this evolution is a feature called RCS Rich Cards.

In this article, we'll explore how RCS Rich Cards work, compare them to alternative messaging technologies including traditional SMS, email, and push notifications, and help you determine which approach best serves your customer engagement goals.

What Is RCS Messaging?

RCS, or Rich Communication Services, is a next-generation messaging protocol designed to replace standard SMS. Supported natively on Android devices and increasingly on iOS (since iOS 18), RCS enables businesses to send interactive, multimedia-rich messages directly to customers' default messaging apps — without requiring them to download a separate application.

Unlike traditional SMS, which is limited to 160 characters of plain text, RCS supports images, videos, carousels, action buttons, verified sender IDs, and — most importantly — Rich Cards.

How RCS Rich Cards Work

Understanding how RCS Rich Cards work is essential for any business looking to modernize its messaging strategy. At their core, Rich Cards are structured message templates that combine visual and interactive elements into a single, self-contained unit delivered within a messaging thread.

Two Types of RCS Rich Cards

RCS supports two primary Rich Card formats:

• Standalone Rich Cards: A single card containing a hero image or video, a title, a description, and up to four suggested action buttons. Ideal for promoting a single product, event, or offer.
• Rich Card Carousels: A horizontally scrollable series of cards, each with its own image, headline, and CTA buttons. Best suited for showcasing product catalogs, service options, or step-by-step instructions.

Anatomy of a Rich Card

Each RCS Rich Card typically includes the following components:

• Media: A high-resolution image or video that anchors the card visually
• Title: A short, attention-grabbing headline
• Description: Supporting text that provides context or detail
• Suggested Actions: Clickable buttons such as "Shop Now," "Get Directions," "Call Us," or "Track Order"

Rich Cards are rendered natively within the messaging app, meaning the customer doesn't need to click a link to access content. The experience is seamless, fast, and familiar — all within the conversation thread they already trust.

Delivery and Interaction Flow

When a business sends an RCS Rich Card through an RCS-enabled platform like SMSGatewayHub, the message is delivered via the RCS Business Messaging (RBM) protocol. The customer receives the card in their native messaging app, interacts with it (tapping buttons, scrolling carousels), and the business receives real-time analytics on delivery, read status, and button interactions. This two-way, data-rich flow is one of the most powerful differentiators of RCS Rich Cards.

RCS Rich Cards vs. Traditional SMS

Traditional SMS remains one of the most reliable messaging channels available, boasting a 98% open rate and near-universal device compatibility. However, SMS has significant limitations when it comes to engagement depth.

Verdict: SMS wins on universal reach, but RCS Rich Cards dramatically outperform SMS in engagement depth, interactivity, and brand presentation. For businesses with an Android-heavy audience, RCS Rich Cards represent a significant upgrade.

RCS Rich Cards vs. Email Marketing

Email remains a dominant digital marketing channel, but it faces well-documented challenges: average open rates hover around 20–25%, and deliverability issues, spam filters, and inbox clutter regularly suppress performance.

RCS Rich Cards, by contrast, arrive in the messaging inbox — a space consumers check far more frequently and with far greater intent. Key differences include:

• Open Rates: Business SMS and RCS messages achieve open rates of up to 98% vs. 20–25% for email
• Speed: RCS messages are read within minutes; emails may sit unread for days
• Design Complexity: Email supports complex HTML templates, but RCS Rich Cards offer a streamlined, mobile-first visual experience without the need for HTML coding
• Interactivity: Both channels support CTAs, but RCS buttons trigger native device actions (calls, maps, URLs) instantly — no browser redirect required
• Personalization: Both channels support dynamic content insertion, though RCS makes personalization feel more conversational

Verdict: Email excels at long-form content and detailed product communications. RCS Rich Cards win for time-sensitive promotions, appointment reminders, and transactional messages where immediacy and interaction are critical.

RCS Rich Cards vs. Push Notifications

Mobile app push notifications are another popular engagement tool, but they come with a fundamental barrier: customers must have your app installed and must grant notification permissions. Research shows that fewer than 50% of users accept push notification requests.

RCS Rich Cards bypass this barrier entirely by delivering directly to the native messaging app — no app download required, no permission prompt needed (beyond carrier-level opt-in compliance). Additional contrasts include:

• Rich Media: Both support images, but RCS Rich Cards support full carousels and embedded video
• Persistence: Push notifications disappear quickly; RCS messages remain in the conversation thread for reference
• Two-Way Communication: RCS supports conversational replies; push notifications are typically one-directional
• Analytics: RCS provides granular delivery and interaction data; push notification analytics vary by platform

Verdict: Push notifications work well for app-centric businesses, but RCS Rich Cards offer broader reach with richer interactivity — making them the stronger choice for businesses without a dedicated app.

Real-World Use Cases for RCS Rich Cards in Business

Understanding how RCS Rich Cards work in practice helps clarify their business value. Here are high-impact use cases:

• E-Commerce: Send a Rich Card Carousel showcasing new arrivals with individual "Add to Cart" buttons per product
• Travel & Hospitality: Deliver boarding pass confirmations or hotel check-in details with interactive maps and check-in buttons
• Healthcare: Send appointment reminders with "Confirm," "Reschedule," or "Cancel" action buttons
• Financial Services: Notify customers of transaction alerts with instant action options for fraud reporting
• Retail: Promote flash sales with countdown messaging and a direct "Shop Now" CTA

When to Use Traditional SMS Alongside RCS

It's important to note that RCS and SMS are not mutually exclusive. A best-practice strategy involves using RCS Rich Cards as the primary engagement format while falling back to traditional SMS for devices that don't yet support RCS. This hybrid approach — often built into platforms like SMSGatewayHub — ensures maximum reach without sacrificing engagement quality.
