Conversational Marketing in Malaysia: Making WhatsApp Your Main Channel
Your customers already live on WhatsApp. Here is how to turn it into a two-way marketing channel that people welcome, what the rules are in Malaysia, and how it runs on Salesforce.
The short version
In Malaysia, WhatsApp is where customers already talk, to family, to colleagues and to the businesses they buy from. Industry estimates put WhatsApp use at around nine in ten online Malaysians, which is more than any email list will ever reach.
Conversational marketing means using that channel for two-way conversations, not one-way blasts: a timely message, a customer who replies, and an AI agent or a person who answers straight away. Done well, it shortens the time from interest to sale. Done badly, it gets your number blocked.
Below: why it works, five ways to use it, the rules you have to follow, and how it runs on Salesforce.
Why messaging apps, and why now
Customers expect a reply, not a newsletter. People read WhatsApp messages within minutes, and they reply. Email still matters for detail, but the first response increasingly happens in a chat.
AI can now hold the conversation. Until recently, opening a two-way channel meant staffing it. AI agents such as Agentforce can now answer common questions, check an order or book a meeting at any hour, and hand over to a person when it matters.
Your own data is worth more. With browsers and privacy rules limiting third-party tracking, a customer who opts in to hear from you on WhatsApp is one of the most valuable relationships you can build.
What a good conversation looks like
The difference from bulk messaging is that every message invites a reply, and someone, or something, is ready to answer it.

Five ways to use it
The rules you have to follow
Opt-in comes first. WhatsApp requires customers to agree to hear from you on WhatsApp, and Malaysia's Personal Data Protection Act requires consent for direct marketing. Record when and where each customer opted in, and make it easy to stop.
Business-started messages use approved templates. When you start a conversation, Meta must have approved the message template first. Once the customer replies, you can chat freely within a 24-hour customer service window.
You pay per message, by type. Since 1 July 2025, WhatsApp charges per template message rather than per conversation, with marketing messages priced higher than utility and authentication messages. Replies inside the customer service window are free, so conversations that customers start cost less.
Privacy rules have tightened. The 2024 amendments to the PDPA, in force in stages during 2025, require organisations to appoint a data protection officer, report data breaches, and they raise the maximum fine to RM1 million. Treat your WhatsApp lists and chat history as personal data, with access controls and clear retention.
Frequency matters. Customers who feel spammed block the number, and a high block rate can limit how many messages you are allowed to send. Fewer, more useful messages perform better.
Beyond WhatsApp
WhatsApp leads in Malaysia and Indonesia, but it is not the only messaging channel. LINE is the everyday app in Thailand and Taiwan, Instagram and Facebook Messenger DMs suit lifestyle and retail brands, and TikTok reaches a younger audience. The principles are the same on every app: consent first, useful messages, fast replies and one record of the conversation.
How it runs on Salesforce
For Salesforce customers, WhatsApp can sit inside the systems you already use, rather than in a separate tool with its own customer list.

Marketing Cloud adds a WhatsApp step to a Journey Builder journey, a Flow can send a template when a record changes, and replies can go to an Agentforce agent that checks records and updates details in the conversation. When a person is needed, Service Cloud routes the chat with its full history, so the customer never has to repeat themselves.
How to measure it
| Measure | Why it matters |
|---|---|
| Reply rate | Shows whether messages start conversations, not just get delivered |
| Time to first reply | The faster you answer, the more replies turn into sales |
| Conversion to meeting or order | Links the channel to pipeline and revenue |
| Opt-outs and blocks | An early warning that you are sending too much or the wrong thing |
| Cost per conversation | Compares WhatsApp with email, calls and paid ads |
