Your Ultimate Guide to RCS

Chapter 01

RCS 101: What Exactly is RCS?

If you’re reading this resource, you’re likely new to the idea of RCS in marketing and looking for straightforward answers to foundational questions, like “What the heck is RCS?!”

Rich Communication Services (RCS)

Rich Communication Services (RCS) is a new(ish) messaging protocol that allows you to send branded and interactive messages directly into recipients’ text message inbox without requiring them to download another app.

“Rich” in this context means that, unlike text-only SMS messages or the lower-quality visuals available via MMS, RCS supports high-resolution images and videos, buttons, carousels, typing indicators, read receipts, and more. Additionally, it allows businesses to create branded text experiences, with their name, logo, and colors.

RCS takes texting to the next level, enabling you to engage with audiences in highly dynamic, visual ways that drive powerful results.

  • Branded Messaging — Display your brand logo, colors, and verified identity with every message sent.
  • Rich Media Content — Send high-resolution images, videos, GIFs, and interactive carousels natively.
  • Interactive Actions — Add suggested replies, action buttons, and deep links for one-tap engagement.

RCS vs SMS & MMS: How RCS Compares to SMS and MMS

Content types Text only Text, images, GIFs, videos, audio Text, high-res images, GIFs, videos, audio, plus interactive buttons & carousels

Frequently asked questions

What’s the difference between SMS, MMS, and RCS character limits?

SMS supports up to 160 characters, MMS up to 1,600, and RCS supports 3,000+ characters.

What content types can SMS, MMS, and RCS send?

SMS sends text only. MMS adds images, GIFs, videos, and audio. RCS sends all of those plus high-resolution media, interactive buttons, and carousels.

How are SMS, MMS, and RCS delivered?

SMS and MMS travel over the carrier network. RCS is delivered over mobile data or WiFi, with SMS as an automatic fallback when a device or carrier doesn’t support RCS.

What sender identity does each protocol use?

SMS and MMS send from a 10-digit number or short code. RCS sends from a verified business profile (an RCS Agent) showing the brand’s name and logo.

Is RCS more secure than SMS and MMS?

Yes. SMS and MMS are not encrypted; RCS messages are encrypted.

Verified Sender: Building Trust with Every Message

90%

of executives think their customers trust them

30%

of customers actually do

61%

of consumers spend more with brands they trust

Customer loyalty relies on trust. But, unfortunately, trust is becoming harder to earn and maintain. According to a PwC survey, while 90% of business executives think customers trust their companies, only about 30% actually do. And four in 10 customers stopped purchasing from a company after losing trust in the brand.

What Verified Sender Status Means

A verified sender profile, also known as an RCS Agent, shows recipients that your brand has been authenticated by mobile network carriers. Like a blue checkmark on a social media profile, this status lets your contacts know your messages are coming from a legitimate source — not a malicious impersonator.

Chapter 04

Engagement: Why RCS Experiences Shine

Every day, people are bombarded with so many ads, alerts, and notifications that their brains tune them out — a phenomenon psychologists call “inattentional blindness.” The best way brands cut through the noise is by delivering content that’s simple, visually interesting, and highly relevant. RCS makes all of that easier — here’s how.

Captivating Visual Appeal

Designed images, videos, GIFs, and rich media — polished, curated, and easy to digest.

Interactive, App-Like Design

Rich cards, carousels, and CTA buttons open maps, web pages, or calls — without leaving the conversation.

Strong Trust & Security

Verified sender profiles ease fears about spoofing and spam, building audience confidence.
