Takeaway. The free WhatsApp Business app already does greeting messages, away messages and quick replies at zero marginal cost. Most teams never exhaust it before paying for a platform.
The deadline. Meta's per-message billing has applied since 1 July 2025, and from 1 October 2026 service messages and utility templates sent inside an open 24-hour window stop being free.
What pays. An auto-reply that only acknowledges receipt is the flow least worth paying for. The ones that pay are the flows that end in a booked slot or a qualified contact.
What doesn't. Scheduled personal sends are a phone trick, not a business automation. Anything you build there breaks when Meta ships native scheduling.
Almost every guide to this topic sells you an API on the first scroll. That skips the part that decides your budget: the free WhatsApp Business app is not billed per message, and the WhatsApp Business Platform is. The sequencing that saves the most money is to squeeze the free app until a specific flow visibly earns its own message fees, then move that one flow up.
That matters more in the next few weeks than it has in two years. Two of the free levers people have relied on since late 2024 close on 1 October 2026.
What WhatsApp automation costs after 1 October 2026
Meta moved the WhatsApp Business Platform from per-conversation to per-message billing on 1 July 2025. Every template is priced individually at a rate set by the recipient's country code, so any article quoting a flat cent figure for "a WhatsApp message" is quoting one market and hoping you don't check.
Two exemptions are ending. Per Meta's WhatsApp pricing documentation, service messages have not been charged since November 2024, and utility templates delivered inside an open 24-hour customer service window have been free alongside them. Both become chargeable on 1 October 2026.

Watch this. If your reminder flow was built on "the customer wrote first, so utility templates are free", price it again before October. Weekly sends versus monthly sends stop being a rounding difference.
The exemption that survives is the free entry point: a Click-to-WhatsApp ad or a Facebook page button opens 72 hours of free messaging of any type, which makes ad-click flows the cheapest place to test automation at all. The tier structure sits in our breakdown of WhatsApp Business API pricing.
The two ways to automate WhatsApp, and which one you need
There are exactly two surfaces. The free WhatsApp Business app runs on one phone and covers three automations. The WhatsApp Business Platform runs through a provider, has no message caps, and bills per template.
| Free Business app | Business Platform (API) | |
|---|---|---|
Greeting, away, quick replies | Yes | Yes |

The honest split: under roughly thirty inbound chats a day with one person owning the phone, the free app is the correct answer and a platform is an expense with no matching outcome. Once two people need the same number, or a chat has to become a CRM contact, the free app runs out of room and no workaround fixes it. That is where a shared live chat inbox starts doing real work rather than duplicating the phone.
How to set up automatic WhatsApp messages in the Business app
This is the free half, and it takes about ten minutes. The steps below are for the WhatsApp Business app on Android or iOS, not the personal WhatsApp app, which has no auto-reply of its own.
Step 1: Open Business tools
In the WhatsApp Business app, open Settings (the three dots on Android, the Settings icon on iOS) and choose Business tools. Greeting message, Away message and Quick replies all live here. If you only see the standard chat settings, you are in the consumer app and need to install WhatsApp Business instead.
Step 2: Turn on the greeting message and give it a next action
Tap Greeting message, switch it on, and write the text. This fires for a first-time contact or after 14 days of silence, so it is the single most valuable line you will write all year. Do not spend it on "thanks for your message". Put your booking link in it, generated once with our WhatsApp link generator so the customer can act without waiting for you.
Step 3: Set the away message to a real schedule
Tap Away message, switch on Send away message, then set Schedule to Outside of business hours rather than Always send. Always send is the setting that makes customers think the account is unattended, and it fires even when you are two seconds from replying. Choose Recipients if you want it limited to everyone except your regulars.
Step 4: Save quick replies as keyboard shortcuts
Under Quick replies, add the four or five answers you retype every week: pricing, opening hours, where to park, how to reschedule. Each gets a slash shortcut, so typing /price expands the whole reply. Not automation in the strict sense, and it saves more minutes per week than anything else here.
Tip. Write the away message so it survives being read at 3am on a Sunday. A time-bound promise ("we reply by 9am on weekdays") beats an open-ended "we will get back to you soon", which sets no expectation and so cannot be met.
The five flows worth building
Ranked by payback, not by how impressive they look in a demo.
1. Greeting message with a booking link
The cheapest automation in existence, and the only one on this list that costs nothing at any volume. A first-time contact arrives, gets a one-line welcome, and gets a link that shows real availability. If you do nothing else in this article, do this.
2. Away message that names an alternative
An away message that only says "we are closed" converts nothing. An away message that says "we are closed, here is the booking page, here is the emergency number" turns dead hours into slots. In a 40-comment r/AskMarketing thread on automating WhatsApp replies, the recurring ask is not for cleverness but for the customer to get something actionable the moment they write, which is what an alternative-naming away message does.
3. Appointment confirmation and reminder
This is the flow with a measurable outcome attached: fewer no-shows. It needs the Platform, because the message has to fire off a calendar event rather than off an inbound chat. A confirmation goes out at booking, a reminder goes out 24 hours ahead, and both carry a reschedule link so a cancellation lands as a freed slot instead of an empty chair. The mechanics are the same ones behind automated workflows and booking confirmations, and the wider case sits in our guide to appointment reminders. For healthcare practices this is usually the flow that pays for the whole channel.
Price it against October, though. If your reminders currently ride the free utility window, they get a per-message cost in a few weeks, and a 24-hour reminder to every booking is a very different line item from a 24-hour reminder to bookings worth more than a threshold you set.
4. The scheduled personal send, which you should skip
Search volume for sending a WhatsApp message automatically at a set time is real and mostly consumer. The routes people share are iOS Shortcuts automations and Android apps like SKEDit, and the threads document how brittle they are: a 50-comment r/shortcuts thread on sending a WhatsApp message automatically works through time-of-day automation workarounds, a separate 20-comment r/shortcuts thread on auto-replying to WhatsApp messages concludes there is no native way to reply based on message content, and the r/tasker discussion covers the accessibility-service route that breaks on Android updates.
Two reasons not to build a business process on any of it. These automations run on a single phone that has to stay signed in, so they die with that phone. And WhatsApp has been rolling out native scheduled sending, which retires the workaround entirely. Use the Platform's scheduled campaigns for anything that matters.
5. AI agent that qualifies and books
The top of the range, and the only flow that changes what a chat is for rather than how fast it is answered. Instead of routing to a human, the agent answers from your own documented knowledge, asks the two or three questions that decide whether an enquiry is worth a meeting, and books the slot in the conversation. That turns WhatsApp into a lead qualification surface, and each conversation lands as a record rather than as a notification. The design tradeoffs are covered in our piece on the conversational AI chatbot pattern.
Caution. An agent that books is only as good as the calendar behind it. If your availability is maintained by hand, automate the calendar before you automate the chat.
Templates you can paste in
Three that cover most of the free app. Replace the bracketed parts and keep them short, because WhatsApp truncates long messages behind a "read more" on mobile.
Greeting message:
Hi, thanks for messaging [Company].
We usually reply within [X] hours on weekdays.
If you already know what you need, book a time here: [booking link]
Away message, outside business hours:
Thanks for your message. We're closed right now and reply from [09:00] on [weekdays].
Book a slot yourself, any time: [booking link]
Urgent? [alternative channel]Appointment reminder, sent 24 hours ahead:
Reminder: your appointment with [Company] is tomorrow, [date] at [time].
Address: [address]
Need to change it? [reschedule link]
More variants, including the wording that actually reduces no-shows, are in our appointment reminder text templates.
Where meetergo fits
meetergo's WhatsApp Business app connects a WhatsApp Business number to a booking calendar and a CRM in one place, so the chat and the appointment are not two systems that someone has to reconcile. Chats run in the browser with no phone in the loop, get assigned across the team, and sit next to the contact's record. Booking links and form links send with one click, and every conversation becomes a contact in the built-in CRM tagged with WhatsApp as the source. Routing rules from routing forms and lead capture mode apply to chat-originated bookings the same way they apply to web ones.
The AI agent answers from your company knowledge, checks real availability, books in the chat, detects the customer's language and replies in it, and hands over to a person with the full thread as context. It runs on Mistral in France and Melious in Germany, hosted in Europe with no US cloud in the path and no CLOUD Act reach, and prompts are processed to generate the reply and then not stored or used for training. The details of that posture are on our security page.
Pricing is per number rather than per seat: €39 per WhatsApp number per month with unlimited team members (checked 2026-09-09), with additional numbers for separate locations or service lines billed individually. Full plan detail is on the pricing page.
The honest limitation: this is a WhatsApp Business Platform product, so Meta's per-message fees apply on top of the subscription, and the October change lands on your account the same way it lands on everyone else's. What it does not do is make you buy a platform to get greeting and away messages, which the free app gives you for nothing.

Five mistakes that make WhatsApp automation backfire
Check these before you switch anything on
The one that costs the most is the third. WhatsApp quality ratings are per number, they fall on user blocks and reports, and a low rating throttles how many people you can message per day. Automation makes it faster to reach that state, which is why an opt-in step belongs in front of any campaign flow rather than behind it.
FAQ
Can WhatsApp send messages automatically?
Yes, in two ways. The free WhatsApp Business app sends greeting messages, away messages and quick replies triggered by an incoming chat. The WhatsApp Business Platform sends templates triggered by your own systems, such as a booking, a payment or a form submission. Personal WhatsApp has no built-in automation.
How do I set an automatic reply on WhatsApp without a business account?
You cannot do it natively. Personal WhatsApp has no auto-reply, and the workarounds are Android apps that read notifications, or iOS Shortcuts automations. Both run on a single signed-in phone and break on OS updates. Installing the free WhatsApp Business app on the same number is the supported route.
Is WhatsApp automation free?
The WhatsApp Business app and its three automations cost nothing at any volume. The Business Platform charges per message at a rate set by the recipient's country, plus whatever your provider charges. From 1 October 2026, service messages and utility templates inside an open 24-hour window are charged too.
How many WhatsApp messages can I send per day?
It depends on your number's quality rating and verification status, not on your plan. New numbers start with a low daily limit on business-initiated conversations and move up as the rating holds. Blocks and reports push the rating down and the limit with it.
What is the difference between the WhatsApp Business app and the API?
The app is a free phone application for one person on one number, with three fixed automations. The API, now called the WhatsApp Business Platform, is a connection your software uses, supports a whole team in a browser, allows conditional logic and AI replies, and bills per message.
Which WhatsApp automation should a small team build first?
The greeting message with a booking link, because it costs nothing and converts an enquiry into a slot without a human. Add the away message second. Only move to the Platform when a specific flow, usually appointment reminders, has a number attached to it that beats its own message fees.
Where to start this week
Install the free app, write the greeting message with a real booking link in it, and set the away message to business hours. That is an afternoon and it costs nothing. Then take your reminder volume, multiply it by a per-message rate for your main market, and decide before 1 October whether that flow earns its keep. If it does, it is the one to move onto the Platform first. If it does not, you have just saved yourself a subscription. Teams that live in chat all day, particularly customer support teams, usually find the answer flips the moment two people need the same number.
