Why does messaging matter to businesses?

Why do businesses prefer WhatsApp?

Messaging has become an indispensable part of modern communications.

Facebook CEO Mark Zuckerberg recently said “People increasingly want the intimacy of connecting privately. Messages are by far the fastest-growing areas of online communications. We all need to communicate privately, and this service is becoming more important in our lives.”

Every 24 hours, 100 billion messages are sent on Facebook’s Messenger, WhatsApp, and Instagram Direct messaging platforms. WhatsApp is simple, reliable, and secure, and with 1.5 billion users, WhatsApp is the global leader in messaging.

How have customer expectations changed?

How do businesses use WhatsApp API?

61% of people prefer to message a business than to pick up the phone and 59% of people prefer to message a business than to send an email. To better reach their existing and prospective customers, businesses need to adapt to messaging. 

A harsh reality check — while nearly 7 in 10 business surveyed think that they’re communicating effectively with their customers. But just 2 in 10 customers surveyed agreed.

Customer engagement is critical. Based on global consumer surveys, 89% of respondents expect a company to respond to them within 24 hours and 80% of respondents say that the experience a company provides is as crucial as its goods and services. Further, 52% of respondents switched companies because of poor customer service.

Why use WhatsApp?

With 1.5 billion users in 180 countries using 60 languages, WhatsApp’s mission is to connect the world through real-time communication. WhatsApp creates digital living rooms/lounges where people have control over their personal, private conversations.

9 out of 10 of the messages sent on WhatsApp are from one person to another and the majority of groups on WhatsApp have fewer than ten people.

What is WhatsApp’s value to businesses?

Example Use Cases

WhatsApp wants to enable any person, no matter what country they’re in and what language they speak, to be able to discover, communicate, and transact with any business. 

Businesses depend on WhatsApp because of its reach (every single day, 102 million WhatsApp messages are sent to businesses around the world), engagement (64% of WhatsApp users agreed that WhatsApp fostered a personal connection to businesses), and preference (68% of WhatsApp users agreed that WhatsApp is the easiest way to connect with a business). People want to message businesses throughout the customer journey, from pre-purchase to purchase to post-purchase.

And compared to other messaging channels, WhatsApp messages have higher delivery, higher open and higher conversion rates.

How can businesses get the most out of WhatsApp?

Why Businesses Prefer UIB WhatsApp Business Account

WhatsApp enables any person to discover and communicate with your business. Startups and SMEs can interact easily with their customers on WhatsApp by using the WhatsApp Business app (available from the Apple Store and Google Play) to easily automate, sort, and respond to messages. Businesses of all sizes can communicate with customers at scale using the WhatsApp Business API (available from UIB) for customer care and notifications. 


Customer care messages are responses to customer-initiated conversations on WhatsApp. They enable companies to:

  • Resolve issues one-on-one with private conversations;
  • Connect with instantly with prospective and existing customers; and
  • Communicate with customers on their preferred channel.

UIB customers using customer care on the WhatsApp Business API have seen increases in customer satisfaction and customer service operational efficiency, and a decrease in customer service operations spend.

Notifications enable companies to:

  • Deliver important, timely messages to your customers;
  • Continue the conversation with customers who respond to your notifications; and
  • Use different message templates across the customer journey.

UIB customers using notifications on the WhatsApp Business API have seen an increase in opt-in rates, delivery rates, open rates, conversion rates, and customer retention rates.

How do businesses get a verified WhatsApp account?

WhatsApp Business Account

Getting the green verification tick for your WhatsApp Business account requires separate approval. UIB will pursue this approval for our customers with WhatsApp. Note that verification does not impact your WhatsApp Business account’s functionality or ownership (not all businesses have verified accounts).

How does pricing work?


Responses to customer-initiated conversations are not charged by WhatsApp if you send replies within 24 hours of a customer’s message. Responses after 24 hours are charged as notifications. 

Notifications are charged by WhatsApp per message. Messages are priced based on how many notifications businesses send within each market (i.e., the country code of the recipient’s phone number, see WhatsApp’s public rate card. WhatsApp has significant volume discounts so companies pay progressively lower prices as their message volumes increase.

How do businesses use template and normal messages?

UIB Use Case: du

du is a vibrant, multiple award-winning telecommunications service provider serving over nine million individual and business customers with its mobile, fixed-line, broadband internet, residential, ICT, and managed services. du’s goal was to improve its customer service by making it faster and fun.

du collaborated with UIB to use WhatsApp for customer care by launching “Blu” – a multi-channel, AI-based virtual assistant on WhatsApp and Facebook Messenger. 

du’s UnificationEngine-powered Blu helps customers to instantly get answers to questions they previously answered by calling up the Contact Centre or visiting a du retail store.

UIB Use Case: DEWA

DEWA used UIB’s WhatsApp Business API and its UnificationEngine Conversational AI platform to deploy their customer service virtual assistant, “Rammas,” on WhatsApp.

Rammas is DEWA’s virtual assistant, designed to assist customers and answer their questions. Answering instantly, Rammas analyzes customers’ questions, checks the available data and information, and then answers their questions. If customers questions can’t be answered by the virtual assistant, they will be directed to a customer service agent. Since launching, Rammas has responded to over two million customer questions.

How does this benefit DEWA’s customers?

Launching conversational customer service in Arabic and English means DEWA customers can access Rammas 24/7/365 on WhatsApp with zero wait time. They can use Rammas to answer queries (e.g., how to set up a new account) and access services (e.g., check and pay bills). Users simply scan a QR Code or click on a link to add Rammas to their smartphone’s contacts. They message Rammas “Hi” on WhatsApp and let Rammas guide them through how to use it.
