WhatsApp auto-reply: the three ways, and which one fits
"WhatsApp auto-reply" is three different things under one name, and they differ widely in what they can do and what they cost. Most people searching for the first need the third, and do not know it exists.
1. The three ways side by side
| Way | Understands the question? | Cost | Fits |
|---|---|---|---|
| Away message in the Business app | No — one fixed text | Free | Telling a customer you are closed |
| Keyword rules | Partly — it matches what you wrote | Included in the platform | Menus, buttons, a known short list of questions |
| AI replies | Yes — it reads intent, not letters | Platform + Meta fees on conversations you start | A store asked questions it did not anticipate |
2. Where the away message stops
It is the fastest thing to switch on and the least you can expect from it. It sends the same text to everyone: the one asking a price, the one complaining about a late order, and the one wanting to cancel. All three messages then sit waiting for you unchanged.
It is entirely enough when your goal is that the customer knows you will reply in the morning. It is not enough when your goal is not to lose them before morning.
3. When keyword rules are enough
A rule fits what is finite and known: a menu of buttons, an answer to "1" and "2", a single word like "address". It stops when the customer writes in their own words, which is what they usually do:
- Three phrasings of one question, none of which is the word you wrote.
- Latin-letter writing: "bekam" does not match the Arabic word.
- A misspelling — the most common thing in typing from a phone.
That is why AI has become the practical layer: it understands all three phrasings without your writing any of them.
4. Switching on AI replies
- Connect your number on the WhatsApp Business API — minutes through Meta's embedded signup.
- Give it what it knows: your prices, shipping and returns policies, the questions customers repeat. This decides quality more than any setting.
- Set working hours: who answers by day and who by night.
- Set the human handover — and when the bot pauses because a person joined the conversation.
- Review weekly the questions it could not answer; each is a missing line in what it knows.
5. The mistake that spoils an auto-reply
The bot and a person both replying. When an employee opens the conversation in Meta's own app or in the platform and types, and the bot keeps answering, the customer sees two contradictory voices. The bot should pause the moment a human types and resume when the conversation ends — and that is behaviour to test yourself before trusting it.
Frequently asked
How do I switch on the away message in WhatsApp Business?
In the WhatsApp Business app: Settings, Business tools, Away message. You write one text and choose when it sends — outside business hours or always. It is free, but it is one fixed text that does not read the customer's question.
What is the difference between keyword rules and AI?
A rule matches a word you wrote in advance: whoever types "price" gets the price reply. AI understands intent: "how much", "what are your prices" and a misspelling all reach the same answer without your writing any of them.
Does an auto-reply stop my staff from replying?
It should not. The correct setup pauses the automation the moment a person types in that conversation, and resumes after it ends. That is what stops the bot and the employee both answering the same customer.
Can I auto-reply only outside working hours?
Yes, and it is the most common setup: the team answers by day and the automation covers nights and weekends. The automation can capture what the customer needs and hand it to the team first thing.
