A2P (Application-to-Person) messaging has evolved considerably in recent years to become an essential resource for corporate communication. This growth responds to the need for companies to establish more direct, effective and personalized interactions with their customers.
A2P (Application-to-Person Messaging) refers to automated messages sent from an application to a user. They are usually used for relevant notifications, such as verification codes, bank alerts or booking confirmations, and are transmitted via an API or web platform.
What is RCS (Rich Communication Services)?
RCS (Enriched Communication Services) is a mobile messaging channel natively integrated into devices and designed to optimize communication between businesses and customers. Its functionality allows users to receive messages enriched with multimedia content, such as images and videos, within the same certified SMS app. It also offers advanced features such as read receipts and customized business profiles.
RBM (RCS Business Messaging)
RBM is the term used to describe the application of RCS in business environments. Through RBM, companies interact with their customers through enriched messages, thus achieving greater participation and improving the communication and user experience. In addition, these tools increase levels of loyalty and cross and upselling.
RCS vs. SMS: Advanced Features That Traditional SMS Can’t Offer
RCS’s advanced features are the capabilities that technically set it apart from SMS and MMS: verified brand identity, unlimited multimedia content, interactive CTA buttons, typing indicators, and real-time read receipts.
Verified identity and brand personalization: security guaranteed
RCS stands out as a highly secure channel with multiple anti-phishing protection mechanisms. This makes it an ideal choice for sectors that handle sensitive data, such as finance and banking.
Only companies that have been verified by Google can use this channel, which guarantees its authenticity. RCS messages include the brand logo and allow companies to create customized profiles with contact details, email, phone number, a brief description of the business and visual elements such as banners and calls to action.
Multimedia content: more engaging interactions
Unlike traditional SMS, RCS allows high-quality multimedia content to be sent, making the user experience more engaging. With up to 1,000 characters available for messages, brands can include text, images, product carousels, videos, voice notes, interactive buttons and quick responses.
Encouraging interaction: CTA buttons and pre-designed responses
RCS transforms traditional messaging into a conversational experience. Thanks to the integration of response buttons, customers can interact with the brand in a simple and effective way.
Other CTA (Call to Action) options such as “Buy now”, “Visit our site” or “View offer” generate more engagement and increase conversion rates. In addition, each interaction is monitored in real time. In this way, companies can evaluate the performance of their campaigns through metrics such as opens, reads and clicks, often in real time.
How does RCS differ from traditional SMS?
Advanced features beyond SMS
RCS messages include features similar to those found in messaging apps such as WhatsApp, Messenger, and iMessage, including support for high-resolution images, videos, and GIFs for a more immersive experience.
RCS Outperforms MMS: Multimedia with No Size Limits and No Loss of Quality
Unlike MMS, RCS allows the sending of multimedia files without size limitations or loss of quality, so that communication becomes more visual and attractive.
RCS: compatible with multiple carriers and brands, with no platform restrictions
While platforms like iMessage are limited to certain devices, RCS is compatible with multiple carriers and phone brands, ensuring that the enhanced messaging experience is consistent and accessible.
Read Receipts and Writing Indicators: RCS Interactivity
RCS includes features such as read confirmations, typing indicators and group chats, providing a smoother and more natural user experience.
RCS for Businesses: Automated and Interactive Messages That Boost Engagement
Companies can leverage RCS to improve customer interaction through automated messaging, interactive invitations and rich content that captures their attention.
RCS use cases
- RCS makes it easy to build long-lasting relationships with customers. Following a purchase or shipment notification, companies can invite users to sign up for their loyalty program through an engaging CTA.
- To increase average purchase value, it is key to apply personalized cross-selling and up-selling techniques. With RCS, companies can integrate these strategies into automated notifications, effectively driving sales.
- While contact centers are essential for resolving queries, RCS enables you to anticipate the most frequent queries by proactively sending relevant information prior to customer interaction. This reduces customer information or clarification needs and generates resource and cost savings.

Frequently Asked Questions
What is RCS, and how is it different from SMS?
RCS (Rich Communication Services) is the successor to SMS, designed to offer a more comprehensive messaging experience: it allows users to send images, videos, carousels, and interactive buttons, and to verify the identity of the sender. Unlike SMS, which only supports plain text, RCS integrates these features directly into the phone’s messaging app, without the need to install any additional apps.
What is RBM (RCS Business Messaging)?
RBM (RCS Business Messaging) is the specific RCS application for business-to-consumer (A2P) communications. Through RBM, businesses can send verified messages featuring their logo and brand name, rich multimedia content, call-to-action (CTA) buttons, and even manage two-way conversations. Only businesses verified by Google can use RBM, which ensures the sender’s authenticity and reduces the risk of phishing.
In which industries is RCS particularly useful for businesses?
RCS is particularly useful in industries where the customer communication experience is critical: banking and finance (security alerts, transaction confirmations with verified identity), retail and e-commerce (shipping notifications with interactive tracking, loyalty campaigns), insurance (renewals with call-to-action buttons), telecommunications (personalized offers), and any industry looking to elevate its A2P communications beyond traditional SMS.
Do my customers need to have an app installed to receive RCS messages?
No. RCS is natively integrated into the device’s messaging app: on Android, in the Google Messages app; on iPhone, Apple has built-in RCS support starting with iOS 18. This means that the recipient receives rich messages directly in their regular SMS app, without having to download anything. If the recipient’s device doesn’t support RCS, the message can be automatically sent as a fallback SMS.
How can a company start using RCS in its communications?
To use RCS in B2C communications, a company must: (1) be verified by Google as a legitimate sender for RCS Business Messaging; (2) have an A2P provider or platform that manages the delivery and orchestration of RCS messages; (3) design rich message templates (images, buttons, carousels) according to each carrier’s specifications. Omnichannel communication platforms such as Communicalia from MailComms Group allow companies to manage RCS alongside other channels from a single platform.
