How to Implement RCS Rich Cards Step-by-Step to Boost Customer Engagement

Why You Need a Hands-On Implementation Plan for RCS Rich Cards

You've probably heard the buzz around RCS Rich Cards and how they're reshaping business messaging. But here's the thing — knowing what RCS can do and actually implementing it are two very different challenges. Most guides stop at the theory. This one doesn't.

In this guide, we'll walk you through the entire implementation journey — from registering your brand to sending your first interactive RCS Rich Card campaign. Whether you're a marketing manager, a developer, or a business owner, you'll have a clear roadmap by the end of this article.

Step 1: Audit Your Current Messaging Strategy

Before jumping into RCS, take a hard look at what you're currently doing. Pull up your existing SMS campaigns and ask yourself these questions:

• What's your average open rate and click-through rate on traditional SMS?
• Are customers responding to your calls-to-action, or are messages being ignored?
• Do you have campaigns that would benefit from images, carousels, or action buttons?
• What percentage of your audience uses Android devices with RCS-capable messaging apps?

This audit gives you a baseline. You'll use it later to measure exactly how much improvement RCS messaging brings to your customer engagement metrics.

Pro tip: Export your last 90 days of SMS campaign data. You'll want delivery rates, response rates, and conversion numbers handy.

Step 2: Choose the Right RCS Business Messaging Platform

Not all RCS providers are created equal. You need a platform that offers:

SMSGatewayHub's RCS messaging platform checks every box above and offers free testing credits so you can experiment before committing budget. That's where you want to start.

Step 3: Register and Verify Your Brand Agent

Here's where the actual setup begins. In RCS terminology, your business identity is called an Agent. Think of it as your brand's verified profile inside the customer's native messaging app.

What You'll Need to Prepare:

• Brand name (as you want it displayed to recipients)
• Logo — high-resolution, square format (minimum 224x224 pixels)
• Brand color — hex code for your primary brand color
• Hero image — a banner image for your agent profile (1440x448 pixels recommended)
• Description — a concise tagline about your business (max 100 characters)
• Contact details — phone number, website, email
• Privacy policy URL — mandatory for verification

Submit these assets through your RCS provider. SMSGatewayHub handles the Google RBM (RCS Business Messaging) verification process on your behalf, which typically takes 3–7 business days. Once approved, your brand appears as a verified sender — no more anonymous phone numbers.

Step 4: Design Your First RCS Rich Card

This is the fun part. RCS Rich Cards are essentially mini landing pages delivered directly inside the messaging app. Here's how to design one that actually converts:

Anatomy of a High-Converting Rich Card:

• Media (Image or Video): Use a compelling product image or a short video (max 10 seconds for autoplay). Dimensions: 1440x1440 pixels for standalone cards.
• Title: Keep it under 25 characters. Make it action-oriented. Example: "Flash Sale — 50% Off"
• Description: 2–3 lines maximum. Focus on the benefit, not the feature. Example: "Your favorite sneakers at half price. Today only. Tap below to grab yours."
• Suggested Actions (Buttons): You get up to 4 buttons. Use them wisely:

Standalone vs. Carousel — When to Use Each:

Use a standalone Rich Card for single-focus messages — like an appointment reminder, a delivery update, or a flash sale. Use a carousel (up to 10 cards that users swipe through) when you want to showcase multiple products, plan options, or menu items.

For example, a restaurant could send a carousel with 5 cards — each featuring a different meal combo with a "Order Now" button. A real estate agency could show 6 property listings, each with an image, price, and "Schedule Visit" action.

Step 5: Integrate RCS API with Your Existing Systems

This is where how businesses can use RCS messaging at scale becomes real. You'll want to connect the RCS API to your existing tech stack:

• CRM Integration: Trigger personalized Rich Cards based on customer lifecycle events (new sign-up, abandoned cart, loyalty milestone)
• E-commerce Platform: Auto-send order confirmations with product images, tracking buttons, and delivery Rich Cards
• Marketing Automation: Schedule campaigns, A/B test card designs, and set up drip sequences
• Customer Support: Send suggested reply chips so customers can respond with one tap instead of typing

SMSGatewayHub provides well-documented APIs with sample code in Python, PHP, Java, and Node.js. Most development teams can complete the integration in 2–4 days.

Step 6: Test Before You Launch

Never skip testing. Here's a quick checklist:

• Device testing: Send test Rich Cards to at least 5 different Android devices from different manufacturers (Samsung, Xiaomi, OnePlus, Google Pixel, Vivo). Rendering can vary slightly.
• Failover testing: Send to a non-RCS device and confirm the SMS fallback works correctly with your shortened URL and plain-text CTA.
• Button testing: Tap every single button. Does the URL open correctly? Does the phone number dial? Does the calendar event save properly?
• Load testing: If you're planning a campaign to 100,000+ contacts, run a smaller batch of 1,000 first to check delivery speeds and error rates.
• Content review: Double-check for typos, broken images, and accurate pricing. Rich Cards look professional — a typo stands out 10x more than in plain SMS.

Use the free RCS testing credits from SMSGatewayHub to run these tests without spending your campaign budget.

Step 7: Launch, Monitor, and Optimize

Once you've tested everything, it's go time. But launching isn't the finish line — it's the starting point for optimization.

Key Metrics to Track from Day One:

• Delivery Rate: What percentage of messages were successfully delivered as RCS vs. fell back to SMS?
• Read Rate: Unlike SMS, RCS gives you actual read receipts. Aim for 70%+ read rates.
• Button Tap Rate: Which buttons are getting clicked? This tells you what your customers actually want.
• Conversion Rate: Track how many taps converted into purchases, sign-ups, or appointments.
• Opt-out Rate: If this spikes, your messaging frequency or content needs adjustment.

Optimization Tactics That Work:

A/B test your card images. We've seen businesses increase tap rates by 35% simply by switching from a product-only image to a lifestyle image showing the product in use.

Experiment with button copy. "Buy Now" vs. "Grab Yours" vs. "Claim 50% Off" — small wording changes can produce significant differences in click rates.

Time your sends. Analyze when your audience is most responsive. For B2C brands in India, we've observed peak engagement between 10 AM–12 PM and 7 PM–9 PM IST.

Segment aggressively. Don't send the same Rich Card to everyone. Segment by purchase history, location, browsing behavior, and engagement level. A carousel showing winter jackets shouldn't go to someone in Chennai in May.

RCS Rich Cards vs SMS: A Quick Performance Comparison After Implementation

Once you've been running campaigns for 30 days, here's what typical performance improvements look like based on aggregated data from businesses using SMSGatewayHub:

The difference between RCS Rich Cards vs SMS isn't incremental — it's transformational. And these numbers compound over time as your audience grows accustomed to interacting with your Rich Cards.

Common Implementation Pitfalls to Avoid

Since this is a how-to guide, let's flag the traps we see businesses fall into during implementation:

• Skipping the failover setup: About 25–30% of mobile users in India still don't have RCS-capable devices. Always configure SMS failover so no customer is left out.
• Overloading cards with text: Rich Cards are visual-first. If your description reads like a paragraph from a legal document, you've lost the plot. Keep it punchy.
• Ignoring consent management: RCS follows the same TRAI regulations as SMS in India. Ensure you have proper opt-in before sending and make opt-out easy.
• Sending too frequently: Just because RCS is more engaging doesn't mean you should message daily. Start with 2–4 messages per month and adjust based on engagement data.
• Not leveraging suggested replies: Suggested reply chips (pre-written response options customers can tap) are one of the most powerful RCS features. They reduce friction and increase response rates by up to 3x.

Your 30-Day RCS Implementation Timeline

Here's a realistic timeline to go from zero to live:

• Days 1–3: Audit current messaging, gather brand assets, choose your RCS provider
• Days 4–7: Submit brand agent for verification via SMSGatewayHub
• Days 8–14: Design your first 3 Rich Card templates (1 standalone + 1 carousel + 1 transactional)
• Days 15–20: Complete API integration with your CRM or e-commerce platform
• Days 21–25: Run testing across devices, fix edge cases, finalize failover messages
• Days 26–28: Launch pilot campaign to a segment of 5,000–10,000 contacts
• Days 29–30: Analyze results, optimize, and plan your full-scale rollout
