RCS Messaging: The Complete Guide for E-commerce (2026)

RCS (Rich Communication Services) is in the middle of replacing SMS on billions of smartphones worldwide. But what is an RCS message exactly? How does it work? And, the question every Shopify merchant is asking in 2026: where does RCS fit in your messaging stack alongside WhatsApp and SMS? This complete guide breaks down RCS technical basics, carrier rollout status, pricing, comparison with WhatsApp, and the cases where RCS makes sense for e-commerce.

For a quick verdict before diving in: in 2026, WhatsApp Business remains the highest-converting messaging channel for Shopify, with 96% open rates and a mature automation ecosystem on top of Kanal. RCS is a meaningful upgrade for transactional SMS, especially for stores already paying for SMS via Twilio or Postscript, but it is not a substitute for WhatsApp marketing for e-commerce.

1. What is an RCS message

RCS (Rich Communication Services) is the successor to SMS. Developed by the GSMA carrier consortium and pushed by Google, RCS turns the native Messages app on your smartphone into an experience close to WhatsApp or iMessage.

Unlike SMS (limited to 160 characters of plain text), RCS supports:

• HD images and videos directly in the conversation
• Action buttons (buy now, book, visit a site)
• Product carousels to showcase your catalog
• Read receipts to know when a message has been seen
• Typing indicators in real time
• Location sharing
• Suggested replies to guide the conversation
• Verified business profiles with logo and brand color

RCS runs over data (Wi-Fi or 4G/5G), not the SMS network. If the recipient has no RCS available, the message falls back automatically to standard SMS. The full technical specs are documented by the GSMA on their Universal Profile page.

2. How to enable RCS messaging

On Android (Google Messages)

1. Open the Messages app from Google
2. Tap your profile photo top right
3. Select Messages settings
4. Tap RCS chats
5. Enable Turn on RCS chats

Most recent Android phones ship with RCS enabled by default via Google Messages.

On iPhone (iOS 18+)

Apple added RCS support with iOS 18 in 2024. To enable:

1. Go to Settings then Messages
2. Enable RCS Messaging

RCS messages between iPhone and Android now appear with improved green bubbles. Apple's full documentation is on the iOS RCS support page.

On Samsung

Samsung has used Google Messages by default since 2022. Activation follows the same Android procedure above.

4. RCS vs WhatsApp: which channel for marketing

The question every Shopify merchant is asking: should you bet on RCS or on WhatsApp marketing?

Advantages of RCS for marketing

• No specific opt-in app needed (built into the native Messages app)
• No app to install, runs directly on the phone
• Verified business identity, brand name and logo are displayed
• Automatic SMS fallback if RCS is not available
• Universal reach on Android handsets with carrier RCS

Advantages of WhatsApp for marketing

• 96% open rate (vs ~70% for RCS)
• 3 billion monthly active users globally
• End-to-end encryption by default, more secure
• AI chatbots integrated for automation, see Kanal AI chatbot
• Business API mature and well-documented
• No carrier dependency, runs everywhere over the internet
• Identical experience across iOS and Android
• Conversational threads that feel like a real chat, not a one-way blast

Our recommendation

For Shopify e-commerce in 2026, WhatsApp remains the highest-performing channel:

• WhatsApp open rates (96%) far exceed RCS (~70%)
• The WhatsApp Business ecosystem is more mature (API, chatbots, integrations)
• WhatsApp works identically across all operating systems; RCS still has differences between Android and iOS
• WhatsApp automation tooling is years ahead of RCS, see our deep dive on WhatsApp Business templates

That said, RCS is an excellent complementary channel, especially as fallback when WhatsApp is not available.

With Kanal, you can combine WhatsApp and SMS/RCS in an omnichannel strategy to maximize reach and conversions.

5. RCS for e-commerce: use cases

1. Abandoned cart recovery

RCS lets you send rich messages with the product image, price, and a "Complete my order" button directly in the message. However, for abandoned cart recovery, WhatsApp posts conversion rates 3 to 5x higher than RCS thanks to its higher open rate.

2. Order notifications

RCS messages are perfect for order notifications: confirmation, shipping, delivery. The customer sees the info directly in the native messaging app without opening another app. This is one of the strongest use cases for RCS today: replacing transactional SMS with richer formats.

3. Promotional campaigns

RCS carousels let you showcase multiple products in a single message. Great for flash sales, seasonal collections, or personalized offers.

For more sophisticated campaigns with advanced segmentation, WhatsApp broadcasts offer more options, including Klaviyo and Shopify integration.

4. Customer support

RCS supports two-way conversations but does not natively integrate AI chatbots. For 24/7 automated customer support, WhatsApp with an AI chatbot remains the most effective solution.

6. RCS campaigns: how to launch your first one

Prerequisites

1. Sign up with an RCS aggregator (Sinch, Vonage, Twilio)
2. Business verification with Google
3. Create a Business profile with logo and colors
4. Phone number database with marketing consent

RCS campaign costs

Costs vary by aggregator and country:

• US/UK/EU: $0.03 to $0.08 per RCS message
• SMS comparison: $0.04 to $0.07 per SMS
• WhatsApp comparison: $0.05 to $0.10 per conversation (via Meta pricing)

RCS is often priced like SMS but offers a much richer experience. For pricing details across all WhatsApp categories, see our WhatsApp Business pricing guide and WhatsApp vs SMS pricing by country.

8. Brands using RCS in 2026

Several large brands have already deployed RCS in their customer communication strategy:

• Air France: booking confirmations and flight alerts via RCS
• BNP Paribas: 2FA authentication and transaction notifications
• DHL and UPS: package tracking with real-time location
• Walmart: promotional campaigns with product carousels
• Vodafone: billing notifications and data offers with action buttons
• Subway: loyalty program offers and store locator

RCS is particularly used by carriers and services that send heavy volumes of transactional SMS and benefit from the engagement bump (40 to 60% CTR vs 6 to 8% on plain SMS).

9. RCS benchmarks: open rates and conversion

Based on the most recent studies (GSMA, Sinch, Mavenir 2025-2026):

Sources: GSMA RCS reports, Sinch State of Customer Communications, and our own WhatsApp marketing statistics 2026.

Note: RCS posts very high CTR thanks to its native action buttons, but its open rate is still limited by adoption (still rolling out in much of Europe and APAC).

10. RCS rollout status by region

In 2026, RCS continues its progression:

• United States: Apple supports RCS on iPhone since iOS 18, eliminating the biggest barrier to adoption. Major carriers (Verizon, AT&T, T-Mobile) all support RCS.
• United Kingdom: BT, EE, Vodafone, O2 deliver RCS via Google Messages.
• France, Germany, Spain, Italy: Orange, Deutsche Telekom, Vodafone, and others deploy RCS progressively. Apple iOS 18.4 added RCS for French carriers in early 2025.
• LATAM, MENA, APAC: rollout is partial, with stronger coverage in Brazil, Mexico, India, and the Philippines.

However, WhatsApp remains dominant globally with more than 3 billion monthly active users, including over 500 million in Europe alone. RCS adoption is following, not leading.

11. The verdict: RCS or WhatsApp for your Shopify store

If you have to pick one channel for your Shopify store in 2026, pick WhatsApp. The combination of open rate, automation maturity, consistent cross-platform UX, and integration with Shopify makes it the dominant choice.

If you already run SMS through Twilio or Postscript, layer RCS on top as the richer fallback. You will get better CTR on transactional notifications (delivery, 2FA, account alerts) without rewriting your stack.

The omnichannel approach wins: WhatsApp for conversational marketing, RCS for richer transactional SMS, and email for long-form. Kanal orchestrates WhatsApp and SMS/RCS from one place, with one shared customer profile.

FAQ

What is an RCS message?

An RCS message (Rich Communication Services) is the successor to SMS. It lets you send enriched messages with HD images, videos, action buttons, product carousels, and read receipts, directly from the native Messages app on your smartphone. RCS is developed by the GSMA and supported by Google on Android plus Apple on iPhone since iOS 18.

Is RCS better than WhatsApp for e-commerce?

For Shopify stores in 2026, WhatsApp still outperforms RCS on key metrics: 96 percent open rate vs around 70 percent for RCS, higher post-click engagement, mature automation ecosystem, and consistent UX across iOS and Android. RCS shines as an SMS upgrade for transactional notifications (delivery, 2FA, account alerts), not as a full marketing channel.

Is RCS available in every country?

RCS rollout is uneven. North America and Western Europe (UK, France, Germany, Spain, Italy) have strong carrier support. Apple's iOS 18 added RCS in the US, with global rollout continuing through 2026. Coverage in LATAM, MENA, and APAC is patchy. WhatsApp, by contrast, runs identically in every country with internet access.

How much does an RCS message cost?

RCS pricing through aggregators (Sinch, Twilio, Vonage) ranges from $0.03 to $0.08 per message in mature markets, similar to SMS. WhatsApp Business conversations cost around $0.065 per 24-hour session in most countries, which works out cheaper per back-and-forth exchange. Pricing also varies by message category (utility, marketing, authentication).

Should Shopify brands adopt RCS in 2026?

Treat RCS as a complement, not a replacement. Use WhatsApp Business for conversational marketing, abandoned cart recovery, post-purchase upsell, and support. Use RCS through your SMS provider as a richer fallback for transactional notifications when WhatsApp is not available. With Kanal you can orchestrate both from one dashboard.

Conclusion

RCS is a major evolution of SMS that brings native messaging closer to WhatsApp features. For Shopify merchants, it is a channel worth watching, particularly to upgrade transactional SMS.

In 2026, WhatsApp remains the highest-performing conversational marketing channel for e-commerce:

• Higher open rate (96% vs ~70%)
• More mature automation ecosystem
• Native Shopify integration
• AI chatbot for 24/7 support
• Consistent UX across iOS and Android
