How to Set Up Auto-Reply on WhatsApp Business (2026 Step-by-Step)

You are asleep, in a meeting, or serving another customer — and a message lands on WhatsApp: "Are you open? How much is a haircut?" If nobody answers within a few minutes, a lot of people simply message the next business. That is exactly the gap a WhatsApp Business auto-reply is meant to close.

In this guide you will set up both native auto-replies (the greeting message and the away message) step by step, learn the schedule and targeting options most people miss, and see where the built-in tools stop — and what "auto-reply" looks like in 2026 when it can actually answer the question instead of just acknowledging it.

The two types of WhatsApp Business auto-reply

The free WhatsApp Business app gives you two automated messages, and it helps to know exactly what each one does:

• Greeting message — sent automatically the first time someone messages you, or when they message again after 14 days of silence. Think of it as your digital "hello, welcome."
• Away message — sent automatically when you are unavailable, either always, on a schedule (e.g. after 6pm), or outside custom hours. This is your "we are closed right now" reply.

Both are fixed text. They are perfect for setting expectations ("thanks, we will reply soon") but they cannot read a question or reply with a price, your hours, or a booking link. Keep that limitation in mind — we will come back to it.

How to set up a greeting message

1. Open WhatsApp Business and tap the ⋮ menu (Android) or Settings (iPhone).
2. Go to Business tools → Greeting message.
3. Toggle Send greeting message on.
4. Tap Greeting message and write your text. Keep it short, warm, and useful — see the examples below.
5. Under Recipients, choose who gets it: everyone, everyone not in your address book, everyone except certain people, or only specific contacts.
6. Tap Save.

A good greeting does three things: welcomes the customer, sets a response-time expectation, and nudges them to share what they need so you can help faster.

Example: "Hi! 👋 Thanks for messaging Bloom Salon. Tell us the service you want and your preferred day, and we will confirm shortly. For prices, just ask!"

How to set up an away message

1. In WhatsApp Business, open Business tools → Away message.
2. Toggle Send away message on.
3. Tap Away message and write it.
4. Choose a Schedule:
   • Always send — useful if you only ever reply during the day.
   • Custom schedule — set the exact hours the away message is active (e.g. 6pm–9am).
   • Outside of business hours — automatically uses the hours on your business profile.
5. Set Recipients the same way as the greeting.
6. Tap Save.

The away message is your safety net for nights, weekends, and busy stretches. It should reassure the customer and, ideally, point them to a self-serve option (your website, menu, or booking link) so they are not stuck waiting.

The schedule and targeting settings people miss

Two details trip everyone up:

• Frequency. Both auto-replies send once per contact per session, not on every message. So a customer who sends five messages gets one greeting, not five. That is by design — it stops the bot from spamming.
• "Already replied" rule. If you have already replied to a conversation, the away message will not fire for that chat during the session. Great for avoiding awkward double-messaging, but it is also the #1 reason people think their away message is "not working."

If your away message truly is not sending, check that: (1) the toggle is on, (2) the schedule covers now, and (3) you have not already replied in that chat.

Where native auto-replies stop — and why it matters

Here is the honest truth every business owner discovers a week in: a greeting or away message is not an answer. The customer asked "how much is a haircut?" and got "thanks, we will reply soon." They still have to wait. Many still leave.

The native WhatsApp Business app cannot:

• Answer a question (price, hours, "are you open now?").
• Reply differently to different people.
• Take a booking or share a booking link based on what was asked.
• Understand a voice note — and a huge share of customers now send voice, not text.
• Reply in the customer's language.

So the native tools are the floor, not the finish line. They buy you a little time. What actually keeps the customer is a reply that resolves their question in the moment.

What "real" auto-reply looks like in 2026

This is where AI auto-reply changes the game. Instead of one canned line, an AI receptionist reads each message (or voice note), understands it, and replies with the actual answer — pulled from your prices, hours, and services — 24/7, in whatever language the customer used.

The difference in a real chat:

Customer asks	Native away message	AI auto-reply
"How much is a haircut?"	"Thanks, we will reply soon."	"A haircut and styling is $25. Want me to book you in?"
Sends a voice note asking to book Friday	(nothing — it can't hear it)	Understands it, offers a Friday slot, confirms
Messages in Arabic	Same English canned text	Replies fluently in Arabic

That is the leap: from acknowledging customers to serving them without you lifting a finger. It is also what stops the "sorry, we missed your message" apologies the next morning.

ChatMunshi is built exactly for this — it plugs into your existing WhatsApp Business number and answers customers around the clock, so your auto-reply does the job a front desk actually does.

Best practices for WhatsApp auto-reply messages

Whatever tool you use, these principles keep your automated replies from feeling robotic:

1. Set a clear expectation. "We reply within an hour" beats a vague "we will get back to you."
2. Give them a next step. Link your menu, booking page, or price list so they are not stuck.
3. Sound human. Use the customer's language and a warm tone — one emoji is plenty.
4. Keep it short. Two sentences. Nobody reads a paragraph from a business.
5. Never over-promise. If you cannot reply until morning, say so — honesty builds trust.
6. Review it monthly. Prices, hours, and offers change; stale auto-replies quietly cost you.

The takeaway

Setting up WhatsApp Business auto-reply takes about two minutes: turn on the greeting and away messages, write clear text, and set a schedule. That alone puts you ahead of every business that leaves customers on read.

But remember what those canned messages can't do — answer the question. If missed replies and after-hours messages are costing you bookings, the next step is an auto-reply that actually resolves the customer's request. That is the difference between a business that says "we will get back to you" and one that quietly closes the sale at 10pm.
