WhatsApp Auto-Reply: Setup, Rules & Examples

Someone messages your business at 9pm. They want a price, a slot, a "are you open Sunday?" — a thirty-second answer. But your team is offline, the message sits unread until morning, and by 9am they've already DM'd a competitor who replied in two minutes. That silence is the most expensive thing on WhatsApp, and it happens every single night.

A WhatsApp auto-reply closes that gap. Done well, it acknowledges instantly, sets expectations, and routes the easy questions to instant answers — so nobody waits and your team isn't typing the same five sentences all day. Done badly, it's a robotic wall that frustrates the people you're trying to win.

This guide covers both kinds of auto-reply — away messages (time-based) and keyword replies (trigger-based) — with rules and copy-paste examples, plus where the built-in WhatsApp options stop being enough.

Two kinds of WhatsApp auto-reply (and when to use each)

Front-loading the distinction, because people conflate these and then wonder why their setup feels clumsy:

Greeting and away messages are time-based: they fire regardless of what the customer said. Keyword replies are content-based: they read the message and respond to intent. The best setups layer all three — a greeting on first contact, an away message after hours, keyword rules handling the FAQs in between.

Setting up an away message in the WhatsApp Business app

The free WhatsApp Business app has basic automation built in. It's the right starting point for a solo operator.

1. Open WhatsApp Business → Settings → Business tools → Away message.
2. Toggle Send away message on.
3. Write your message (examples below).
4. Set the schedule: Always send, Custom schedule (e.g. 6pm–9am, plus weekends), or Outside of business hours (which pulls from the hours on your profile).
5. Choose recipients — usually Everyone, or Everyone not in the address book for first-timers only.

The greeting message lives in the same menu and fires when a customer messages you for the first time, or after 14 days of silence. For the schedule itself, our WhatsApp business hours guide walks through setting hours so your away message switches on and off automatically.

The limits you'll hit fast

The built-in away message is genuinely useful — until it isn't:

• One message, for everyone. You can't say something different to a new lead versus a returning customer.
• No keyword logic. It can't answer "what are your prices?" — it only fires on time, not on what was said.
• One phone, one person. The instant a second teammate needs to see those chats, the app's automation doesn't travel with them.
• Greeting messages are blunt. They fire on first contact regardless of context, so they can feel like a form letter.

For a solo shop these are fine. For a team — or anyone who wants instant answers, not just acknowledgements — you need keyword replies, which the basic app can't do.

Away & greeting message examples (copy-paste)

Good away copy does three things: acknowledges, sets a clear expectation, and gives one next step. Skip the apology marathon. Templates by use case:

General after-hours:

Thanks for messaging [Business]! We're away right now but we've got your message. We reply weekdays 9am–6pm — usually within a couple of hours. For anything urgent, [next step].

E-commerce / D2C:

Hi! Orders placed now are processed next business day. Tracking? Reply with your order number and we'll pull it up first thing. 🛍️

Services / appointments:

Hey, thanks for reaching out! We're closed for the day. To book, reply with your preferred date and we'll confirm a slot in the morning. You can also check availability at [link].

Greeting (first contact):

Welcome to [Business] 👋 Tell us what you're looking for and a real person will jump in shortly. Pricing, hours and location? Just reply "info".

Weekend:

Thanks for your message! We're closed weekends and back Monday 9am. We'll reply in order of arrival — talk soon.

Two rules matter more than the wording: never promise a reply time you can't keep (a missed "within 5 minutes" is worse than no promise), and always end with a next step — a keyword to try, a link to browse, an order number to send. For more patterns, see our greeting and away message examples.

Keyword auto-replies: instant answers to repeat questions

This is where auto-reply stops being a doormat and starts doing real work. A keyword reply watches for a word or phrase in the incoming message and responds instantly with the right answer — no human needed for the questions you field fifty times a day.

The pattern is always the same: trigger → matched response. Here's a starter rule set most teams can ship as-is.

A few rules that separate a helpful keyword setup from an annoying one:

• Match loosely, not exactly. A customer types "wat r ur prices" — match on price appearing anywhere, not the whole phrase.
• Always offer an exit to a human. Keyword loops that trap people are the fastest way to lose trust. Every flow needs a talk to a person escape.
• Don't auto-reply to everything. If a message doesn't match a keyword, stay silent and let your team answer — don't fire a generic "sorry, I didn't understand."
• Cap the bot. One keyword reply, then a human — see WhatsApp chatbot vs smart automations on where to draw that line.

Keyword replies and away messages aren't rivals — they're layers. The away message covers time ("we're offline"); keyword rules cover intent ("here's your answer"). For a deeper build, see keyword-triggered replies on WhatsApp and the broader WhatsApp automation playbook.

Auto-reply rules that keep you out of trouble

Automation that fires too aggressively reads as spam — to customers and, in bulk, to WhatsApp's own systems. Keep these guardrails:

• Only reply to people who messaged you first. Auto-replies are reactive. Never use them to start unsolicited outreach.
• One auto-reply per conversation window. Re-sending the same away message on every message in a thread is the fastest way to get muted or reported.
• Keep it human-paced. A reply that lands the same millisecond every time looks automated. A short, natural delay reads better.
• Give an off-ramp. Every automated flow needs an obvious way to reach a real person.

These habits matter beyond etiquette: patterns that look like a bot blasting identical messages are exactly what trips trust-and-safety systems. Our guide on sending WhatsApp messages without getting banned covers the rest.

Where Tenashi fits

The built-in away message is fine for one person on one phone. The moment you're a team — or you want keyword answers, not just "we're away" acknowledgements — you've outgrown it. That's the gap Tenashi closes.

Tenashi is the WhatsApp workspace for teams. You link your existing WhatsApp number with a QR scan — no new SIM, no porting, no template approvals — and your whole team works one shared inbox with automations built in. That means away messages scheduled to your real hours and keyword auto-replies that hand customers instant answers, with a clean handoff to a real agent the moment a conversation needs one. Because every chat is tied to a contact in a real CRM, the auto-reply isn't a dead end — it's the first step of a tracked conversation your team owns.

Two things the official-API tools (WATI, AiSensy, Interakt) can't match here: Tenashi automations work in groups too, not just one-to-one DMs, and there are no per-message fees — a flat price from $18/mo. Sends stay ban-protected with human-paced timing and burst guards (risk reduction, not a guarantee), so even your automated replies don't pattern like a bot. And on Growth & Scale only, AI can go further than fixed rules — drafting suggested replies your team approves in one tap, instead of every answer being hard-coded.

FAQ

How do I set up an auto-reply on WhatsApp?

In the free WhatsApp Business app, go to Settings → Business tools → Away message, toggle it on, write your message and set a schedule. That covers time-based replies. For keyword auto-replies — instant answers based on what the customer typed — you need a workspace like Tenashi, since the basic app can't read message content.

What's the difference between an away message and a keyword reply?

An away message is time-based: it fires whenever you're outside your business hours, regardless of what the customer said. A keyword reply is content-based: it reads the incoming message and responds to specific words like "price" or "hours" with the right answer. Most strong setups use both together.

Can WhatsApp auto-reply to specific keywords?

The free WhatsApp Business app cannot — it only does time-based greeting and away messages. To trigger replies on keywords like "pricing", "location" or "order", you need a WhatsApp workspace or automation tool that reads message content and matches it to a response, then hands off to a human when needed.

Will auto-replies get my WhatsApp number banned?

Auto-replies to people who messaged you first are normal and safe. Risk comes from firing identical messages repeatedly, replying instantly every time like a bot, or using automation for unsolicited outreach. Keep one reply per conversation, human-paced timing and an exit to a real person to stay well within bounds.

Should every message get an automatic reply?

No. Auto-reply your away message after hours and your keyword answers when there's a clear match — but stay silent on messages that don't match a keyword, and let your team handle them. Firing a generic "sorry, I didn't understand" on every unmatched message frustrates customers more than a short, honest wait.

Can a team share WhatsApp auto-replies on one number?

Not with the built-in app — its automation lives on one phone. A shared WhatsApp workspace like Tenashi connects your existing number for the whole team, so away messages and keyword replies fire for everyone, and any teammate can pick up the conversation from a shared inbox once the auto-reply has done its job.
