RCS will come in handy as the Indian e-commerce market continues to evolve and adapt to changing consumer demands. With the industry projected to reach US$ 325 billion by 2030, experiencing significant growth, RCS will play a key role in enhancing customer engagement and driving business success.

RCS (Rich Communication Services) is a modern messaging protocol designed to enhance traditional SMS, offering businesses in India and globally a more interactive and feature-rich way to connect with customers. RCS comes as a complimentary solution to connect with consumers in a more engaging and personalized way.

So, the next immediate question that pops in our mind is, how does RCS allows for personalized communication?

  • The RCS messages include customer specific details, such like names, purchase history, behavior, location -based offers and also, the needs. All these metrics helps in getting to know the customers better, and so businesses can tailor their services accordingly. For example, a shoe store offering customized deals, like
Hi Neha, it's great to see you again! We’ve noticed you recently purchased a pair of running shoes and we think you might love these new arrivals in our store.
Adidas Ultraboost 22 (Available in your size!)
Nike Air Zoom Pegasus 39 (20% off today!)
  • RCS supports quick-reply buttons, sliders, suggestions for further purchase, browsing history, these features create intuitiveness, and so users can navigate and interact with the system more easily. This makes the entire experience  seamless and foster greater engagement. For example, when booking a flight via RCS, users get options like  checking flight status, changing seats, airport location or adding luggage etc.
  • India has rich linguistic diversity, so for businesses to expand their reach and create impactful communication, they can create messages in a customer’s native language. RCS can help creating personalized, rich messages in preferred language, which will resonate with the local culture and lifestyle. Customers will then feel more comfortable navigating, making purchases and even seeking assistance in their own language. It’ll also help in increasing the relevancy and emotional connection. For example, a clothing brand promoting regional festivals or local trends can create a deeper and personal connection with customers, resulting in better engagement, niche market penetration and eventually foster loyalty & growth from customers.

After all, RCS has the potential to touch base with one-to-one, conversational experience between enterprises and their customers.

Standout Features of RCS

RCS is a tool to complement SMS and MMS as it provides a more detailed user experience, similar to popular messaging apps. It is operated via internet (data or Wi-Fi) for message delivery rather than the cellular network. Here are some standout features of RCS:

  • Rich Media: Supports high-resolution images, videos, GIFs, and other multimedia content.
  • Interactive Elements: Includes features like sliders, buttons, suggested actions, quick replies, tracking elements and forms, which allow for direct engagement within the message.
  • Larger File Sizes: Allows for sharing of larger files up to 10MB or even 100MB in some cases.
  • Verified Business Profiles: Provides verified sender IDs with logos and branding, which enhances trust and security.
  • Read Receipts and Typing Indicators: Offers real-time feedback on user engagement.
  • No Character Limit: RCS does not cap the character limit, so loner and richer messages can be sent across devices.
