There is no better thing a company can do than have open and transparent communication with customers as their best tool for success.
The better customer engagement, the higher the retention rate will be. In fact, 87% of customers trust a brand with top-notch communication.
Yet, many businesses fail to maintain smooth communication and keep on juggling between different communication channels. This often results in project delays and client losses.
Deciding between RCS vs WhatsApp business vs SMS is the biggest common confusion most business owners experience. Well, they all come up with their own set of pros and cons. That is why businesses must pick a suitable option based on their expectations and goals.
Let's understand and learn about each line of communication basis which you can decide which will be the best fit for your business.
A Quick Comparison Between RCS vs WhatsApp Business vs SMS
RCS messaging is the modern version of SMS which is a standard feature on mobile phones. Among some of the significant attributes are high-resolution media, real-time interactivity, and high security.
SMS messaging is the traditional method of communicating with anyone under 160 characters. While WhatsApp business messaging is the ultimate powerhouse for conversation with a 3x higher conversion rate than the traditional SMS.
Let's have a quick glance at the difference between these three customer messaging channels.
| Features | RCS | SMS | |
|---|---|---|---|
| Primary Channel | Native messaging apps | Third-party messaging app | Cellular network |
| Internet Required | Yes | Yes | No |
| Media & Interactivity | High-resolution media | High-resolution media with voice notes | Under 160 characters only |
| Security | Transport encryption | End-to-end encryption | None |
| Business Verification | Verified business profiles | Blue tick badge | Sender ID |
Which Customer Messaging Channel Works Best for Engagement
In comparison to RCS Messaging vs WhatsApp Business vs SMS, Customer Experience is the ultimate deciding factor. The reason is simple; every communication channel has a role to play. Some are best for reach, while others are just for interactive chit-chat with customers.
1. Customer Reach and Accessibility
If reaching the maximum number of customers is your top priority, SMS remains difficult to replace. Customers get the SMS no matter if they have their internet on or not, while on WhatsApp Business a user must have an app and internet support.
However, it makes for a more conversational experience once customers come online
RCS business messaging sits somewhere in between. It is operated natively in existing messaging applications, and brands can use RCS to deliver communications to customers without downloading an additional app. Given the rise in RCS messaging, businesses are widely making use of it for enhancing the customer journey.
2. Customer Engagement and Interaction
The difference is becoming quite significant here. SMS remains best for sending notifications, one-time passwords (OTPs) and notifications. However, it leaves a limited scope for actual conversation.
While considering between WhatsApp vs SMS, WhatsApp allows for more engaging conversations via media sharing, quick replies, catalogues and more interactive messaging, enabling businesses to address customer queries, send leads nurtures and execute transactional conversations.
Meanwhile, RCS Messaging offers similar interactive capabilities. Businesses can use rich media like images, carousels, buttons, and personalized branding to engage customers to trigger the desired action. It almost goes without saying that organizations engaged in large-scale communication should explore the combination of multiple customer messaging platforms instead of one.
3. Integration and Business Scalability
Customers don't just receive messages anymore - with conversational commerce; businesses can track customer engagement, individualize messages, and automate responses all in one interface.
Businesses consider using Salesforce RCS Messaging features to associate customer interactions with the data stored in the CRM, including automation. This helps teams maintain context from one campaign to the next across conversations.
When to Use RCS, WhatsApp, or SMS?
There’s no single messaging channel that works for everyone. What’s the right fit for you will depend on what you want to achieve from your communication and how your customers want you to communicate.
SMS
Best for alerts, OTPs, reminders and anything with a broad audience to reach.
Great for conversations, customer service and personalization. Compared with SMS, WhatsApp has rich interactivity but requires internet access.
RCS business messaging
Suitable for engaging conversational campaigns, on-brand messages and empowering interactive rich messaging in native apps.
Native rich messaging
Great for conversational campaigns, branded messages and enabling rich experiences inside native messaging applications.
Typically, enterprises don't tie themselves to a single platform; rather, a mix of various customer messaging platforms serves to reach customers and drive their engagement at multiple stages of their customer journeys.
Final Verdict: RCS vs SMS vs WhatsApp Business
There is not a definitive winner between RCS, WhatsApp and SMS; each has its own niche and serves to fulfill various objectives that your business may have.
E.g. if you are trying to send information to a large audience that requires a more general messaging function, then SMS is a proven and reliable means of communication.
If, conversely, the objective is to initiate conversation and build engagement with a personal touch through interactive exchanges with your customers, the WhatsApp business would be an ideal pick.
RCS Messaging brings the right blend of easy accessibility and interactive experience, while providing you with an interactive experience.
For most businesses aiming to improve customer engagement, it is better not to limit themselves to just one messaging application. Most organizations use multiple channels for customer messaging to provide an interconnected experience to their customers across marketing, support, and service touch points.
The decision of which messaging service you will use will be primarily determined by the fact: where your customers are and your preferred method of interaction with those customers.
