WhatsApp Business Auto Reply: Setup, Rules and Limits
How-to — — by Mahmoud Zalt
Set up greeting and away messages in the WhatsApp Business app, what to write in them, and the point where a fixed auto reply stops helping.
The reason you are looking this up is probably a message that sat unanswered for nine hours, and a customer who went somewhere else. An auto reply does not solve that, but it buys you the thing you actually lost, which is the customer's patience.
People will wait a long time for a business that told them how long they would wait. They will wait about twenty minutes for one that said nothing. That gap is worth ten minutes of setup, and it is the honest case for auto replies.
This guide covers both message types, what to write in them, and the specific point where a fixed block of text stops being enough. At that point you either hire a person to watch the inbox or you hire an AI Employee from Sistava to answer properly, and the second half of this guide is about telling those two moments apart.
What are the two auto reply types in WhatsApp Business?
A greeting message and an away message. Meta describes the greeting message as automatically sending a custom welcome message to new customers when they start a conversation, and the away message as responding automatically to messages received outside your business hours to set expectations.
They fire on different triggers, which is the part people mix up. The greeting is about who is messaging and whether the conversation is new. The away message is about when they are messaging, measured against the schedule you set.
There is a third tool alongside them that is not technically automatic but does most of the work in practice. Meta describes quick replies as shortcuts for messages you frequently send, so you can respond to common questions in a few taps. You still press the button, but you stop retyping the same paragraph.
| Tool | Fires when | You write | Best used for |
|---|---|---|---|
| Greeting message | Somebody starts a conversation with you | One welcome message | Setting the tone and asking for the detail you always need |
| Away message | A message arrives on the schedule you set | One out-of-hours message | Naming a real reply time so nobody is left guessing |
| Quick replies | You choose to send one | Several short answers | The six questions you answer every single week |
How do you set up an away message in WhatsApp Business?
Open the WhatsApp Business app, go into its business tools, choose the away message, turn it on, write the text and set the schedule. That is the entire procedure, and it works the same way on every platform even though the menu labels shift around.
The greeting message sits next to it in the same business tools section and follows the same pattern. Write it once, choose who receives it, and turn it on. Nothing here needs a developer, a plan upgrade or an integration.
Setting up both auto replies
- Open the app's business tools — In the WhatsApp Business app, look in settings for the business tools section. It groups the greeting message, away message, quick replies, labels and your catalog together.
- Turn on the away message and write it — Say when you actually reply, not that you will reply as soon as possible. A named time is the difference between a customer waiting and a customer leaving.
- Set the schedule to match reality — Match your real working hours, including the lunch hour you genuinely cannot answer in. An away message that fires while you are visibly online reads badly.
- Turn on the greeting message and write it — Two lines. One that welcomes them, one that asks for what you always end up asking for anyway, like the model, the date or the address.
- Load your six most repeated answers as quick replies — Pricing range, opening hours, where to park, what you need from them, how long the job takes, what happens next. Two taps each from then on.
- Test both from a second phone — Message your own business number as a stranger, out of hours and in hours. Read what comes back with fresh eyes before a customer does.
The schedule step is where most setups go wrong. If your away message fires at 6pm but you answer messages until 9pm most evenings, customers get told you are closed by a business that is plainly open. Set the schedule to the hours you will genuinely defend, then defend them.
What should a WhatsApp auto reply actually say?
Three things, in this order: that you received the message, when a person will reply, and what they can do in the meantime. Anything beyond those three is decoration. Anything missing one of them leaves the customer doing the guessing you were trying to spare them.
Write it in your own voice rather than in customer service language. Thank you for contacting us, your message is important to us, is text nobody has ever been reassured by. Hi, thanks for messaging, we read WhatsApp at 9am and 4pm and will reply in the next slot, does the same job and sounds like a human typed it.
Benefits
One useful fact
Your hours, your price range, or a link to the thing half of them are asking for. Free information now buys patience later.
An emergency route
If something genuinely cannot wait, say what to do. A phone number for urgent cases costs you nothing and saves the rare bad night.
Your actual voice
WhatsApp is read like a text from a person. Corporate phrasing stands out here far more than it does in email.
When does a fixed auto reply stop being enough?
The moment the same customer needs a second message. A greeting message can acknowledge a question about whether you have availability on Thursday. It cannot look at Thursday. Every question that needs a fact from your business rather than a fact about your business is beyond what fixed text can do.
The second sign is volume of the same question. If you find yourself firing the same quick reply forty times a week, you have not automated that answer, you have made it faster to type. The work is still yours and it still lands on your evening.
That is the gap an AI Employee fills. Instead of a fixed block of text, you brief it once on your business, your prices, your hours and your rules, and it answers each message on its own terms. You can shape one for exactly your business at Sistava, including the hard line about what it must never answer alone.
The limits worth knowing before you rely on this
Auto replies only work inside the WhatsApp Business app, on the phone that holds that account. If you move to Meta's WhatsApp Business Platform, the API that larger setups run on, the built-in greeting and away messages are not there. Automation on that side is something you or your provider build.
There is also a rule that governs everything on WhatsApp, and it is worth knowing even at this level. Meta's documentation says a customer messaging you starts a 24 hour customer service window, and once it expires you can only send pre-approved template messages. So an auto reply can answer somebody who wrote to you, but you cannot casually follow up three days later.
Finally, an auto reply is not a substitute for answering. Customers notice when the only thing they ever receive is the automatic one. Set it, then hold yourself to the time you named in it, because the auto reply is a promise you made in writing. If holding to that promise is the part you keep failing, look at what a Sistava AI Employee covers between your working hours, because the fix there is capacity rather than better wording.
Frequently asked questions
FAQ
Can I set an auto reply on regular WhatsApp?
No. Greeting messages, away messages and quick replies are features of the free WhatsApp Business app, not the standard consumer app. Third-party tools that claim to add auto replies to a personal account work by automating it, which WhatsApp's messaging guidelines list as prohibited behaviour.
What is the difference between a greeting message and an away message?
The trigger. Meta describes the greeting message as a welcome sent to new customers when they start a conversation, and the away message as an automatic response to messages received outside your business hours. One is about the conversation being new, the other is about the clock.
Can both auto replies be on at the same time?
Yes, they are separate settings with separate schedules and they cover different situations. Most businesses run both, with the greeting doing introductions and the away message covering evenings, weekends and whatever hours they will not be answering.
Will an auto reply annoy my customers?
Only if it says nothing. A message that acknowledges them, names a real reply time and gives one useful fact is welcome. A message that thanks them for their patience without telling them anything is the version people find irritating, and it is also the version most businesses send.
Do auto replies work if I use the WhatsApp Business Platform?
The built-in greeting and away messages belong to the WhatsApp Business app. On the Platform, which is Meta's API, automated replies are something you or your provider build, and the same 24 hour customer service window and template rules apply to what you can send.
Can an auto reply answer a real question, like a price?
Only if the price fits in the fixed text you wrote. An auto reply sends the same words to everyone, so it can state a price range but cannot quote a specific job, check availability, or answer a follow-up. That is the point where businesses move to something that actually reads the message.
