You set up automatic replies inside Meta Business Suite, under Inbox then Automations, where instant replies, away messages, and FAQ answers are all free and take about ten minutes to turn on. Viber works differently and has no equivalent free auto-reply for a normal business account, so most small businesses there rely on saved quick replies sent manually. The goal is simple: nobody who messages you at 11pm should be met with silence until morning.
You know the message. "Hi po, open pa kayo?" sent at half past ten, seen at seven the next morning, and by then they have already booked somewhere else. It is not that you were careless. You were asleep, like a person should be. But the business does not know that, and neither does the customer. Catching those messages is the entry point to our AI & automation work.
Why the first reply matters more than the perfect reply
Most people messaging a small business are comparing two or three options at once. The one that answers first often wins, not because they are better, but because they were there. An instant reply that says "we got your message, here are our hours, we'll respond properly in the morning" holds the lead in place. Silence loses it.
Setting up Messenger instant replies, step by step
All of Meta's native automation lives in one place.
- Open Meta Business Suite
- Go to Inbox
- Open Automations
- Choose Instant Reply and toggle it on
- Write your message and save
That is the whole setup. It is free, there is no separate platform fee for using Meta's own native tools, and it applies to anyone who starts a new conversation with your Page.
The three native tools worth turning on
Instant reply fires immediately when someone starts a new conversation, any time of day. This is your safety net.
Away message sends when your Page is set to Away or outside the business hours you set on your Page. Worth knowing: if your Page status is "away," the instant reply may not fire at all, because the away message takes priority. Set one or the other for a given period, not both expecting both to send.
FAQs let you set up common questions with pre-written answers the customer can tap. This is the most useful of the three for a busy business, because it actually resolves the question instead of just acknowledging it.
Writing a reply that doesn't sound like a robot
The most common mistake is treating the first automated message like a courtesy note rather than something that does real work. "Thanks for messaging us!" wastes the moment.
A good instant reply does three things at once:
- Confirms the message went through
- Answers the most common question before it gets asked
- Sets an honest expectation about when a human will reply
"Salamat sa message! We're open Mon to Sat, 9am to 6pm. Prices start at ₱___. If you're asking about booking, reply BOOK and we'll send the slots. We reply to everything by 9am the next day."
Note the honesty in that last line. Do not promise a reply "within minutes" if you cannot deliver it. A broken promise in an automated message is worse than no promise. Keep it short, too. Native auto-replies are commonly capped at around 500 characters, so you cannot write an essay even if you wanted to.
What about Viber?
This is where a lot of advice online gets it wrong, so here is the honest version. Viber does not give a normal small business the same free auto-reply toggle that Messenger does. There are two separate business products, and they are not the same thing:
- Viber Chatbots can send automated messages, but creating and running one carries a monthly maintenance charge. For a solo operator in Calamba, that is a serious monthly cost for auto-replies alone, and usually not worth it at low volume.
- Viber business accounts have been rolling out self-serve features, with the Philippines among the first markets.
The realistic answer for most small businesses: use saved quick replies on Viber and send them manually the moment you see a message. It is not automation, but it removes the typing time, which is most of the friction. Then put your real automation effort into Messenger, where it is genuinely free. Anyone telling you Viber auto-replies are free and easy for a small business is skipping the part where you get the bill.
The rule nobody mentions until it bites them
Meta enforces a 24-hour messaging window. You can reply freely within 24 hours of a customer's message. After that window closes, automated follow-up messages are not permitted under Meta's policy. There are narrow exceptions using approved message tags for specific non-promotional cases, and a separate paid marketing-messages program, but the everyday version is this: automation catches them in the moment, not a week later.
This matters because a lot of guides promise "set up a follow-up sequence that chases leads for a week." On Messenger, that is not how the rules work. Build for speed inside the window instead of drip campaigns outside it.
Make sure a human still follows up
An auto-reply is not a replacement for you. It buys you the hours between the message arriving and you being awake, nothing more. Set a fixed time each morning to work through the overnight inbox, and treat that as a real appointment rather than something you get to eventually.
What we would set up first, in your position
If you only do one thing this week: turn on the instant reply, and put your top three questions into the FAQ answers. Price, hours, and location cover most of what people ask before they buy. That combination alone stops the majority of overnight leaks, and it takes about fifteen minutes. Everything else, the chatbots, the branching logic, the CRM integration, can wait until the volume actually justifies it.
Signs you've outgrown the free tools
Native automation is genuinely enough for a small Page with low to moderate volume. You have outgrown it when you need branching conversations that adapt to what the customer answers, structured lead capture into a spreadsheet or CRM, or multiple staff members working the same inbox without stepping on each other. Until then, paying for a platform is paying for capacity you are not using. When you do reach that point, our guide to writing replies in your own voice with AI keeps the personal tone your customers recognize.
What the official Meta setup actually says
Meta's own documentation splits inbox automation into a short list of free tools: instant replies, away messages, automated greetings, and tappable FAQ answers, all managed from the Automations area of Meta Business Suite. The two official references are Set up Inbox automations in Meta Business Suite on desktop and Create an automated Messenger greeting for your Facebook Page. Everything else written about this topic, including this article, is interpretation on top of those two docs.
Why this matters: a lot of screenshots circulating online show menus that have since moved. Meta rearranges Business Suite often, so when a step-by-step guide does not match your screen, go back to the official doc, find the Automations area, and work from there instead of chasing an outdated walkthrough.
Which tool to turn on for which job
Four free tools, four different jobs. Most businesses need the first three turned on and the fourth only when volume justifies it:
| Tool | What it does | Cost | Turn it on when |
|---|---|---|---|
| Instant reply | Fires automatically the moment someone starts a new conversation with your Page | Free | Always. This is the overnight safety net |
| Away message | Sends when your Page is set to Away or outside business hours | Free | You have real business hours and want them enforced |
| FAQ answers | Shows tappable common questions with your pre-written answers | Free | You get the same three questions daily, usually price, hours, location |
| Automated greeting | Greets people who open a conversation before they type | Free | You want first-time visitors guided to the right question |
| Chatbot platform | Branching conversations, lead capture, team inboxes | Paid, per platform | Volume outgrew the free tools, see the signs above |
Comment replies and Instagram DMs
Two related tools people ask about, both handled from the same Business Suite inbox:
- Comments on your posts are not the inbox. Automated replies to comments are a separate feature from Messenger automations, and Meta offers them for Page posts alongside private replies to commenters. Availability and menus vary by Page, so check the Automations area of Business Suite for what your Page is offered. If the option is not there, your Page type or region does not have it yet.
- Instagram DMs ride the same inbox. If your Instagram account is connected to your Facebook Page in Business Suite, the same instant replies, away messages, and FAQ answers can cover Instagram messages too. Set the wording once for both instead of maintaining two scripts.

Frequently asked questions
Is Messenger auto-reply free for a business Page?
Yes. Instant replies, away messages, FAQ answers and automated greetings are free native tools inside Meta Business Suite. You only pay when you move to a third-party chatbot platform, and for most small Pages you should not.
Can I auto-reply to comments on my Facebook posts?
Automated replies to comments are separate from Messenger automations and depend on your Page. Check the Automations area of Meta Business Suite for what your Page is offered; if the option is not there, your Page does not have it yet.
Does the same auto-reply work on Instagram DMs?
Yes, if your Instagram account is connected to your Facebook Page in Meta Business Suite. The same instant reply, away message and FAQ answers can then cover both Messenger and Instagram.
How long can an auto-reply message be?
Keep it short regardless of the exact cap. Meta's native tools are built for brief messages, and a useful one confirms receipt, answers the top question and sets an honest reply time in two or three sentences.
How do I set up auto-reply on Messenger?
In Meta Business Suite, go to Inbox then Automations, choose Instant Reply and toggle it on, then write and save your message. It's free and applies to anyone who starts a new conversation with your Page. Away messages and tappable FAQ answers live in the same place.
Can I set up a free auto-reply on Viber?
Not the way Messenger allows. Viber Chatbots can send automated messages but carry a monthly maintenance cost, and self-serve business features are still rolling out. For most small businesses the realistic answer is saved quick replies sent manually the moment a message arrives.
Can I send automated follow-ups days after someone messages?
On Messenger, no, Meta enforces a 24-hour messaging window. After it closes, ordinary automated follow-ups aren't permitted (narrow message-tag exceptions aside). Build for speed inside the window, not week-long drip sequences.
