Effective communication is central to business success, particularly as mobile messaging platforms gain prominence in engaging customers. Small business owners, tech enthusiasts, and marketing professionals alike are increasingly leveraging mobile messaging to reach their audiences effectively. But with so many options available, which platform is the best for business communication—WhatsApp, SMS, or Viber?
This post will dissect the advantages and use cases of each platform, offering a comparative analysis to help you decide on the right communication tool for your business.
Exploring SMS (Short Message Service)
SMS, also known as text messaging, is one of the oldest and most reliable mobile communication platforms. Its robust characteristics and widespread adoption make it highly relevant even in today’s technologically advanced world.
Key Features of SMS:
- Ubiquity: SMS works on virtually any mobile phone, regardless of whether it is a smartphone or not. It does not rely on internet connectivity, ensuring it can reach virtually anyone with a mobile device.
- Reliability: With a delivery rate of 98% and nearly instantaneous transmission, SMS offers a reliable way to send time-critical messages to customers.
- Simplicity: Unlike OTT (Over-The-Top) messaging apps such as WhatsApp or Viber, SMS does not require an app installation or a user login—users receive messages directly on their device.
Current Business Use of SMS:
Businesses use SMS for various purposes:
- Promotional Messages: Texts notifying customers about sales, discounts, and events.
- Time-Sensitive Updates: Alerts about shipments, deliveries, or appointments.
- Authentication: SMS is widely used for sending OTPs (One-Time Passwords) for securing online transactions and logins.
While SMS is dependable, it does have drawbacks. It supports only limited multimedia capabilities, and costs may accumulate with large-scale campaigns.
WhatsApp and its Business Applications
WhatsApp, a globally dominant messaging app with over 2 billion active users (as of 2023), is a sophisticated platform for real-time communication. Its introduction of WhatsApp Business has made it a go-to choice for many small businesses and marketers.
Features of WhatsApp:
- Interactive Multimedia:
-
- Share text, images, videos, documents, and location updates seamlessly.
- Enhance customer interactions with rich media attachments.
- High Engagement:
- Average user open rates of WhatsApp messages exceed 90%, making it immensely effective for marketing.
- Secure Communication:
- End-to-end encryption ensures data security.
- WhatsApp Business Tools:
- Labels for organizing customers
- Quick replies for FAQs
- Automated messaging (e.g., greeting and away messages)
Usage in Business Communication:
WhatsApp enables businesses to:
- Communicate directly with customers via real-time chat.
- Share product catalogs and payment links.
- Build personal relationships through conversational marketing.
However, since WhatsApp requires both the business and customer to have the app installed, its reach is inherently limited to active WhatsApp users.
Understanding Viber for Business Communication
Like WhatsApp, Viber is another OTT messaging platform that facilitates multimedia communication. With a strong presence in regions such as Eastern Europe and Asia, it is a contender for geographically specific business markets.
Features of Viber:
- Branded Messaging:
- Viber allows branded business accounts to send promotional messages.
- Interactive Content:
- Businesses can create stickers and interactive campaigns tailored to audiences.
- Group Broadcasting:
- Ideal for community-based engagement.
- Cost-Effective:
- Affordable for sending bulk campaign messages compared to SMS.
Business Applications:
Viber supports business marketers by offering tools to engage diverse audiences interactively. Its sticker packs, creative messaging options, and affordable model make it particularly appealing for those targeting its key geographies.
That said, like WhatsApp, the limitation is its reliance on internet connectivity—if your customer is not on the platform, they are not reachable.
