A message at 9 p.m., a quote requested while you're on a job, a question asked on a Sunday: without a fast reply, each of these is a customer going cold. The WhatsApp automated message is the first building block for never missing one again. This guide walks you through the four automations that power a WhatsApp channel run by an AI sales agent, with ready-to-copy examples by trade — and, above all, the one limit to know between a scripted message and a genuinely smart reply.
What exactly is a WhatsApp automated message?
An automated message is text sent without any action from you, triggered by a specific event: a customer messages you for the first time, contacts you outside your hours, or is waiting on an appointment confirmation. Instead of leaving the message unanswered — or dropping everything to reply to every notification — you set the rule once, and WhatsApp does the rest.
Be careful not to conflate two very different things that share the same name. An automated message can be scripted (the same text every time, whatever the incoming message says) or smart (an AI reads the request and replies in context). The free WhatsApp Business app only does the first. We'll come back to this below, because it changes everything in practice.
Why it became essential in 2026
Customer behaviour has shifted. On WhatsApp, people don't wait: the channel feels instant, just like messaging a friend. In practice, a prospect who messages you and hears nothing within ten minutes assumes you're closed, swamped or not serious — and sends the same message to two other businesses. Speed of first reply is now a decision factor as strong as price.
Yet most requests don't land when you're free. A large share arrive in the evening, at weekends, or while your hands are full. The automated message isn't a comfort gadget: it's what keeps the contact alive during the 16 hours a day you can't reply yourself. To place WhatsApp in your wider strategy, our WhatsApp for business guide lays the foundations before you automate anything.
Why an auto-reply changes the game

The 4 types of automated messages to know
No need to overcomplicate: four automations cover almost every need of a sole trader, a local shop or a small business. Here's how each works and what it's for.
1. The greeting message
This is the first message sent automatically when a new contact writes to you for the first time (or after 14 days of silence). Its job: welcome, reassure and set the expected reply time. A good greeting message confirms the customer is in the right place and that their request has landed, even if no one is behind the screen yet.
2. The away message
It fires automatically outside your opening hours. Unlike the greeting, it manages expectations: it says when you'll be back and, ideally, offers an action in the meantime (leave a number, flag urgency, check a useful detail). It's your night watchman.
3. Quick replies
These are shortcuts: you type a keyword (for example /hours or /price) and WhatsApp inserts pre-saved text. It's not fully automatic — you trigger it — but it cuts the time spent on recurring questions tenfold. Ideal for FAQs: address, base pricing, payment methods, availability.
4. Scheduled follow-ups and reminders
The next level: messages sent automatically at a set time — an appointment reminder the day before, a follow-up on an unanswered quote, a birthday message. These require the API (the free app doesn't do them), but they pay off the most, because they go and fetch the customer instead of waiting for them to come back.
Ready-to-copy examples (by situation)
Here are templates you can adapt by simply changing the name, town and trade. Keep them short: a long automated message is rarely read to the end.
Hi, and thanks for your message 👋 This is [BUSINESS NAME] in [TOWN]. We've received your request and will get back to you very soon. To speed things up, tell us in a word what you need 🙂
Thanks for your message! We're currently closed and reopen [DAY/TIME]. Leave your request and your number and we'll call you back as soon as we open. If it's urgent, add "URGENT" and we'll do our best.
Great question! Our prices depend on the service. For a precise, free quote, just tell us: the type of need, your preferred date and your area. We'll come back with an estimate within 24 hours.
What it changes, trade by trade
The value of automated messages varies by activity. Three concrete examples that speak to most local businesses:
- For a car garage, the away message catches evening breakdowns: the customer leaves their need and the garage calls back at opening instead of losing the job to the recovery service next door.
- For a restaurant, the automatic greeting handles the flow of bookings and questions (menu, hours, terrace) even mid-rush, without pulling a waiter off the floor.
- For a hair salon, the scheduled follow-up reminds clients of tomorrow's appointment and nudges those who haven't rebooked in two months — two automations that fill the diary on their own.
The limit to know: scripted message ≠ smart reply
This is the point most guides skip. The automated message in the free WhatsApp Business app is scripted: it sends the same text whatever the customer wrote. If a prospect asks "do you fix leaks on Sundays?", they get the same "we're closed" as someone who just wanted your opening hours. The message goes out, but the conversation doesn't move forward.
An AI agent on the API does something else entirely: it reads the message, understands the intent, replies specifically ("yes, we do emergency Sunday call-outs — can you give me your address and the nature of the leak?"), asks the useful questions and qualifies the prospect before handing over to a human. That's no longer an answering machine, but a first sales exchange run on its own. The gap is the same one between the app and the API: our comparison of WhatsApp Business API vs the free app shows where the line is crossed.
| Criterion | Scripted message (free app) | AI agent (API) |
|---|---|---|
| Content | Always the same text | Adapted to each request |
| Understands the question | No | Yes |
| Asks follow-up questions | No | Yes, qualifies the prospect |
| Hands over to the team | No | Yes, with context |
| Reminders / follow-ups | No | Yes, scheduled |
| Price | Free | Software (from $89/month) |
How to set up your automated messages
In the WhatsApp Business app, it all happens under Settings → Business tools. There you'll find "Greeting message", "Away message" and "Quick replies". Turn them on, write your texts, set the away-message hours, and you're done. Budget ten minutes for a basic setup.
To go further — understand requests, qualify, follow up, connect a calendar and a CRM — you need the API and software to drive it. The good news: you keep your number, and a guided onboarding avoids any downtime. The complete WhatsApp Business API guide explains that switch step by step.
5 best practices for messages that convert
- Be human, not robotic. An emoji, a warm "hi" and a sign-off with your business name beat administrative-sounding text.
- Always ask for an action. Number, detail of the need, urgency: every message should invite the customer to take a step forward.
- Promise a realistic time. "We'll get back within 24 hours" kept beats "instant reply" never honoured.
- Don't promise what you don't do. No automatic priced quote, no commitment the AI can't honour — the message opens the conversation, it doesn't close the sale.
- Review every 3 months. Hours, offers, tone: an out-of-date automated message looks bad. Five minutes a quarter is enough.
With Reepli: from scripted message to WhatsApp sales agent
Setting up a greeting message is good. But a fixed text doesn't qualify a prospect or fill your diary. Reepli.ai turns these automations into a real sales agent connected to WhatsApp:
- Reepli Essentiel — $89/month: the WhatsApp Conversation agent (which welcomes, understands the request, qualifies the prospect and hands real opportunities to your team) + the built-in CRM, with API access included.
- Optional agents — $45/month each: Appointments (automatic reminders and booking), Follow-up (unanswered quotes, dormant customers), Sales, Instagram and Google Reviews.
- Onboarding — $250 one-off: account verification, migration of your number and guided setup of your automations.
One point that matters on the Google Reviews agent: Reepli.ai never replies for you. The AI suggests a draft reply for each new review, and you validate before publishing. The trial is free for 7 days, no card required, and the team answers any question at [email protected].
In short: start simple, scale up
Start by turning on the three basic messages in the app — greeting, away, quick replies. In ten minutes, you already stop losing evening and weekend requests. Then, the day you realise how many opportunities still slip through for lack of a real reply, take the step to an AI agent: that's when the automated message stops being an answering machine and becomes a salesperson working for you around the clock. The right automated message doesn't just say "we're here" — it moves the sale forward.
