Customers do not wait.
When someone messages your business on WhatsApp and gets silence, they do not sit patiently. They open the next Google result and message your competitor. In Malaysia, where WhatsApp is the default channel for customer enquiries, a missing first reply is often the only reason a new customer leaves.
WhatsApp Business has an auto reply feature built in. Free. No extra tools required. But most Malaysian business owners either never turn it on, or they leave the default "Thank you for contacting us" message that tells the customer nothing useful and does nothing to keep them engaged.
This guide explains how WhatsApp Business auto reply works, when each message sends, and what to write so your auto reply converts, not just acknowledges.
What Is WhatsApp Business Auto Reply?
WhatsApp Business auto reply is a feature in the WhatsApp Business app that automatically sends a pre-written message when a customer contacts your number, either when they message for the first time (Greeting Message) or when they contact you outside your set business hours (Away Message). Both features are free and available to all WhatsApp Business accounts without any API or paid plan. Auto reply is one of the most commonly used features in the WhatsApp Business app.
WhatsApp Business auto reply is not a chatbot. It does not read incoming messages or generate different replies based on what the customer sent. It fires one pre-written message based on a trigger: new contact or outside hours.
That is its strength and its limitation.
The strength: it guarantees that every customer gets an immediate response, even at 2 AM on a Saturday. No missed first impressions.
The limitation: it cannot answer questions. If a customer asks "Do you have parking?" or "How much for a single session?", auto reply responds with your generic greeting, which may not be what they needed.
Understanding this distinction helps you write auto reply messages that do real work within those constraints, rather than expecting the feature to do something it was not designed for.
What Are the Two Types of WhatsApp Business Auto Reply?
WhatsApp Business includes two distinct auto reply types: Greeting Message, which sends to contacts who message you for the first time or after 14 days of inactivity, and Away Message, which sends when a customer contacts you during hours your business has set as closed. According to WhatsApp's official Business documentation, both features run in the background without requiring your phone to be active or online.
Greeting Message
This sends when:
- Someone messages your number for the first time
- An existing contact messages after 14 days with no conversation
Greeting Message is your first impression. It runs any time of day, regardless of your business hours setting. A customer who messages at noon on a Monday when you are with a patient still receives the Greeting Message because they are a new contact.
Away Message
This sends when:
- A contact messages during hours you have configured as away in your Business Hours settings
- You have enabled "Always send away message" mode
Away Message is your out-of-hours reply. It does not send during business hours. If both Greeting and Away conditions apply (new contact, outside hours), Away Message takes precedence.
| Feature | Trigger | Timing | Priority |
|---|---|---|---|
| Greeting Message | New contact or 14-day gap | Any time of day | Away Message overrides if outside hours |
| Away Message | Outside business hours | Only during closed hours | Takes precedence over Greeting |
The 14-day reset on Greeting Message often surprises business owners. A patient who came to your clinic in May and messages again in June is treated as a new contact and receives the Greeting Message again. This can feel impersonal if your message is not written to work for both first-time and returning contacts.
For the full step-by-step process to activate both features, see How to Set Up WhatsApp Business Auto Reply.
When Does WhatsApp Business Auto Reply Actually Send?
WhatsApp Business auto reply sends within seconds of the incoming message, provided the app has an active internet connection. The Greeting Message fires on the first incoming message in a new conversation window. The Away Message fires only when the customer's message arrives during hours marked as closed in your settings. Both run when your device screen is off, but NOT if the app has been force-closed or if the device has no internet access.
This last point catches many business owners off guard.
WhatsApp Business auto reply is device-dependent for the free app. If the phone running WhatsApp Business is off, out of battery, or has no data connection, the auto reply will not send. It is not a server-side feature — it runs on your device.
For businesses where the phone sometimes goes offline overnight (power saving mode, weak signal), this means customers messaging at 11 PM may not receive your Away Message until the phone reconnects.
The WhatsApp Business API, used by platforms like AlwaysON, runs entirely on servers, which means auto reply sends reliably regardless of your phone's status.
What Should Your WhatsApp Business Auto Reply Message Say?
Effective WhatsApp Business auto reply messages do three things: confirm the message was received, set a clear expectation for when the customer will hear back, and offer an immediate next step such as a FAQ link, price list, or location. In our experience working with Malaysian service businesses, messages that include at least one actionable element tend to result in less drop-off and better follow-through than acknowledgement-only messages.
Most WhatsApp Business auto replies fail because they focus on what the business needs ("we'll reply soon") rather than what the customer needs ("here is the information you were probably looking for").

The three-part formula for effective auto reply:
Part 1 — Acknowledge. Confirm the message was received. This reduces customer anxiety ("did my message go through?") and the impulse to follow up immediately.
Wrong: "Thank you for contacting us."
Right: "Hi! We received your message."
Part 2 — Set expectations. Tell customers exactly when they will hear from a real person. Vague language ("soon", "shortly") increases uncertainty. Specific language ("within 2 hours", "by 9 AM tomorrow") builds trust.
Wrong: "We will get back to you as soon as possible."
Right: "Our team replies between 9 AM and 6 PM. If you messaged outside those hours, you will hear from us first thing when we open."
Part 3 — Give immediate value. Give customers something useful without waiting. A price list link, your location, your most commonly asked question answered upfront.
Wrong: "Thank you for your patience."
Right: "While you wait, our pricing and FAQ are at alwayson.my — most customers find their answer there in under a minute."
What Do Effective Auto Reply Messages Look Like for Malaysian Businesses?
Malaysian service businesses — clinics, tuition centres, salons, gyms — achieve better customer engagement when auto reply messages are specific to the business type, include the hours, and give at least one actionable link or response-time commitment. Generic messages that could have been sent by any business in any industry are missed opportunities to build trust before a human even replies.
Here are message templates that work for specific Malaysian business types. These are designed to be useful, not just polite.
| Business Type | Greeting Message | Away Message |
|---|---|---|
| Dental Clinic | "Hi! Thanks for reaching out to [Clinic Name]. We'll confirm your enquiry within 2 hours (Mon-Sat, 9AM-6PM). For urgent dental emergencies, call us at [number]. Services and pricing: [link]" | "Hi! We've received your message. Our team is closed right now and back at [time]. We'll reply first thing when we open. For dental emergencies after hours, please call [number]." |
| Tuition Centre | "Hi! Thanks for your interest in [Centre Name]. Our staff will be in touch within a few hours. Our available classes and 2026 fees are at [link]. Which subject or level is your child looking for?" | "Hi! We've received your enquiry. Our admin team is off for the evening and back at 8 AM tomorrow. We'll respond then. Upcoming trial class dates: [link]" |
| Hair Salon | "Hi! We got your message at [Salon Name]. To book an appointment, let us know your preferred date and service. Our price list is at [link]. We'll confirm within 2 hours." | "Hi! The salon is closed right now (open [hours]). We'll reply to your booking request when we open. You can also book directly via our form: [link]" |
| Gym / Fitness Studio | "Hi! Thanks for reaching out to [Gym Name]. We'll get back to you about membership or class slots shortly. Our trial pass details and current promos: [link]." | "Hi! Looks like you caught us after hours. We'll reply at [opening time]. To lock in a free trial class tomorrow, go to [link] — weekday morning spots fill up quickly." |
Adapt these to match your business name, hours, pricing link, and typical enquiry type. The templates above are starting points — the businesses that perform best on WhatsApp localise these further: Bahasa Melayu greetings for a BM-first customer base, Chinese for communities where that is the primary language.

What Are the Limits of WhatsApp Business Auto Reply?
WhatsApp Business auto reply cannot respond to follow-up questions, branch based on what the customer wrote, remember previous conversations, detect language and switch between English and Bahasa Melayu, or operate when the host device is offline. These are design limits of a free consumer-grade feature, not bugs. Businesses receiving more than 30 to 50 WhatsApp messages per day typically encounter these limits within weeks of turning the feature on.
Here is what you will run into:
One message, no memory. Auto reply fires once when a conversation opens. If a customer replies to your greeting with "actually, can you tell me about your pricing?", nothing happens. They wait for a manual reply.
No keyword matching. You cannot set different messages for customers who mention "appointment" versus "pricing" versus "complaint". Every customer gets the same message.
Language locked. You write one message in one language. A customer who messages in Bahasa Melayu receives your English greeting, or vice versa, unless you have written a message that works across both.
Device dependency. As covered above, the free app's auto reply relies on your phone being online and the app running. Server-side reliability requires the WhatsApp Business API.
14-day gap resets the relationship. Returning customers who have not messaged in two weeks are treated as new contacts. A loyal patient who took a break over school holidays receives the new-contact greeting again, which can feel impersonal.

When Should You Upgrade Beyond WhatsApp Business Auto Reply?
Malaysian businesses typically outgrow WhatsApp Business auto reply when they reach 40 or more messages per day, when the same questions such as pricing, location, and availability are being answered manually every day, or when customer enquiries are going unanswered overnight. At that point, upgrading to a keyword-based or AI-powered tool typically reduces manual handling time considerably while improving response quality and consistency.
Watch for these signs that the built-in tool has reached its ceiling:
You are answering the same questions every day. If "how much?" or "how to book?" lands in your WhatsApp five or more times daily, those questions should be automated, not manually handled one at a time.
Customers follow up before you reply. If customers are sending "hi, any update?" or "sorry to chase", your response time has become visible — and costly.
Messages pile up after 6 PM. A tuition centre that gets enquiries from parents after they finish work, or a clinic that has patients messaging on weekends, loses leads overnight when auto reply cannot answer the actual question.
You have hired someone just for WhatsApp. If you have a dedicated person managing WhatsApp messages, the volume has outgrown the tool. A monthly salary for a customer service staff member in Malaysia runs RM1,800 to 3,000 per month. An AI platform handling the same enquiry volume typically costs RM200 to 500 per month and responds 24 hours a day, seven days a week.
What comes after the free app:
Keyword-based tools via WhatsApp Business API let you set up conditional replies. "How much?" triggers a price list message. "Book" triggers a booking link. "Hours" shares your schedule. These require an official WhatsApp Business Solution Provider (BSP) and cost roughly RM200 to 500 per month.
AI-powered platforms like AlwaysON go further, reading the full message and generating contextual responses. A customer who writes "can my daughter come next Tuesday at 4 if slots are still open?" gets a direct, helpful answer, not a keyword-triggered template.

Frequently Asked Questions
What is WhatsApp Business auto reply?
WhatsApp Business auto reply is a built-in feature of the free WhatsApp Business app that automatically sends a pre-written message when a customer contacts your number. There are two types: Greeting Message for new contacts and Away Message for out-of-hours enquiries. Both are free and require no third-party tools or paid plans, and both send within seconds of the incoming message when the host device is online.
Does WhatsApp Business auto reply work when my phone is off?
No. The free WhatsApp Business app's auto reply relies on the app running on your device with an active internet connection. If your phone is off, in airplane mode, or without data, auto reply will not send until the device reconnects. Businesses that need guaranteed 24/7 auto reply need the WhatsApp Business API via an official provider, which runs server-side and does not depend on device status.
Can I set different auto replies for different types of enquiries?
Not with the built-in WhatsApp Business app. The free version sends one fixed message per trigger and cannot branch based on what the customer wrote. Keyword-based and AI-powered tools available through WhatsApp Business API providers allow conditional replies based on message content. For a full breakdown of what each tier supports, see WhatsApp Auto Reply for Malaysian Businesses.
How do I change my WhatsApp Business auto reply message?
Open WhatsApp Business, tap the three-dot menu at the top right, go to Business Tools, then select Greeting Message or Away Message. Tap the pencil icon to edit the message text, make your changes, and save. Changes take effect on the next incoming message. For full setup screenshots and step-by-step instructions, see How to Set Up WhatsApp Business Auto Reply.
Is WhatsApp Business auto reply enough for a growing Malaysian business?
It depends on message volume. For businesses receiving under 30 to 40 messages per day with mostly simple enquiries, the free built-in feature is a reasonable starting point. Once the same questions repeat daily, messages arrive frequently outside business hours, or response quality starts affecting conversion, upgrading to an API-backed or AI-powered tool typically pays for itself in the first month.
