RCS Marketing: The Complete Guide for E-Commerce in 2026

What is RCS?

RCS (Rich Communication Services) is the successor to SMS. Where SMS is limited to 160 characters of plain text, RCS supports images, videos, carousels, interactive buttons, verified sender identity, read receipts, and typing indicators. All of this is delivered through the native messaging app on the recipient's phone — no separate app download required.

For marketers, RCS represents a step-change in business messaging. Instead of a plain-text SMS with a shortened URL, you can send product carousels where customers swipe through items and tap to buy. Instead of an unknown phone number, your brand name, logo, and verified checkmark appear in the conversation. The engagement rates reflect this: RCS messages see 3x higher click-through rates compared to standard SMS.

In 2026, RCS has reached critical mass. Google Messages supports RCS on approximately 90% of Android devices. Apple added RCS to iOS 18, expanding reach to iPhone users. Major carriers globally support the protocol. The infrastructure is in place — the question is whether your brand will take advantage of it before the channel gets crowded.

How to get started with RCS marketing

Getting started with RCS requires brand verification and carrier registration — a process that RevBridge handles entirely for you. Here's what the setup looks like:

Step 1: Brand registration — RevBridge submits your brand details (name, logo, website, business registration) to the RCS ecosystem. This establishes your verified sender identity — the brand name and checkmark that appear in conversations.

Step 2: Carrier approval — Each carrier that supports RCS must approve your brand for messaging. RevBridge manages the carrier-by-carrier approval process. Most brands are approved within 1-2 weeks.

Step 3: Campaign setup — Once approved, you create RCS campaigns through the same RevBridge dashboard you use for email and SMS. Design product carousels, set up action buttons, and configure fallback SMS for non-RCS devices.

Step 4: Optimization — The MAB engine starts testing RCS variants from the first send — carousel layouts, button text, product ordering, and timing. It also tests RCS vs. SMS vs. other channels to find the optimal path for each customer. Check pricing details for per-message costs.
