How to set up auto-reply on Facebook Messenger
Meta's own instant replies cost nothing and take about two minutes. These are the steps on a computer as Meta's Help Center describes them in November 2026. Menu labels move between rollouts, so look for these names rather than exact positions:
- Log in to Facebook, click your profile picture, choose See all profiles and pick your Page.
- Open the Page, then click Meta Business Suite in the left menu.
- Click Inbox in the left menu, then Automations.
- Click Instant reply, switch it on, and choose Messenger as the channel.
- Type your reply in the text box, then click Save changes.
- Go back to Automations and set up an Away message too, so your off hours state an honest return time.
Keyword replies and away messages: the rules that trip people up
- Five keywords at most. A keyword reply fires on up to five keywords you set.
- Exact and case-sensitive. “Price” and “price” are different keywords, and a message has to match exactly. Add the spellings people actually type.
- Desktop only to set up. Keyword replies are created in Meta Business Suite on a computer.
- Away beats keyword. If a message matches a keyword while your away message is on, Meta sends the away message, not the keyword reply.
- You can make it wait. A keyword reply can be set to go out only after you haven't replied for a set time, such as 15 minutes, so it doesn't talk over you.
Start free: Meta's built-in instant replies
Facebook Pages ship with real automation at no cost: instant replies to first messages, away messages for your off hours, and saved replies you fire manually. Set the instant reply to acknowledge the message and set expectations (“thanks, we reply within a few hours”), and the away message to be honest about when you're back. For a Page with occasional messages, this is genuinely enough.
Two more built-ins live in the same Automations screen and are worth two minutes each. Frequently asked questions shows up to five tappable questions in the chat, each with a pre-written answer, which quietly deflects the “opening hours?” class of message. Keyword replies fires a canned response when a message contains one of up to five keywords you set, matched exactly and case-sensitively, which is precisely as brittle as it sounds.
What the built-ins can't do: answer a question you didn't predict, in words that sound like you. Every real conversation still waits for you.
Auto-reply message samples you can copy
Paste these into the Automations screen and change the bracketed parts. They are deliberately plain: an instant reply that promises more than you deliver (“we answer immediately!”) costs more trust than it buys. If the reply box offers a personalization option, use it to insert the sender's name rather than typing it by hand. For other wording, see these short welcome messages for customers.
- Instant reply. “Thanks for the message, [first name]. It has landed with us and you'll have a proper answer within [two hours] during business hours. If it cannot wait, call [number].”
- Away message. “Thanks for writing. We're closed until [Sunday, 9am] and we answer in the order messages arrive. Yours is in the queue.”
- Keyword: pricing. “Happy to talk numbers. The price depends on [scope], so tell me [the one detail] and you'll get a real figure rather than a range.”
- Keyword: booking. “You can book directly here: [link]. If none of those slots work, tell me what does and we'll fit you in.”
- Keyword: order status. “Send your order number and we'll check it now. If you don't have it to hand, the email address you ordered with works too.”
- FAQ answer: opening hours. “We're open [Sunday to Thursday, 9am to 6pm]. Messages sent outside those hours are answered first thing the next working day.”
- Instant reply for a creator or coach. “Hi [first name], thanks for writing. I read every message myself and reply within [a day]. If it's about working together, add your timeline and budget.”
- Away message, holidays. “We're closed for [Eid] until [date]. Your message is saved and we'll answer it the day we're back.”
- Keyword: location. “We're at [address], next to [landmark]. Map: [link]. Parking is [details].”
- Keyword: refund. “Sorry to hear that. Send your order number and what went wrong, and a person from our team will reply within [one working day].”
What are Messenger quick replies?
Messenger quick replies are tappable buttons that appear above the typing bar, such as “Book a call”, “Prices” or “Opening hours”. The person taps one instead of typing, the buttons disappear, and the button's text is posted into the chat as their answer. Meta allows up to 13 buttons in one message, each title up to 20 characters, and a button can also offer to share the person's phone number or email from their profile.
Quick replies are sent by a bot or flow tool through the Messenger API, not set up in the Page settings. The name causes confusion because two other features get called the same thing: the saved replies you insert by hand from the Meta Business Suite inbox, and the Frequently asked questions buttons from the Automations screen above. For a Page without a bot, those two are the quick replies you can set up today, free.
Flows: when Messenger is a support desk
If your Page fields the same ten questions at volume, keyword flows (ManyChat and similar) route them: menus, FAQ trees, order-status lookups, lead capture. It's the call-center model, and for a business with call-center-shaped traffic it's right. The trade is the same as everywhere: flows are scripts, and customers know when they're talking to one.
Voice AI: when the Page is a person
Full disclosure: this is our product. PersonaXpand is an AI social media manager for personal brands: it writes posts in your own trained voice for all eight networks and auto-replies to comments, DMs and mentions, on one flat plan. For Facebook it answers Page comments and Messenger messages in your trained voice through Facebook's official API, with one-tap approval or autonomous mode for the routine ones. If your Page is your name, a consultant, a doctor, an agent, the reply IS the product, and it should sound like you.
Messenger is also where most of the risky questions arrive: what does it cost, are you open Sunday, where are you, can I book Thursday. Those are the questions generic AI bots answer with confident inventions. PersonaXpand doesn't guess at them. A message asking for something only you know is left for you, and complaints or sensitive messages are held for you rather than answered, so nothing wrong goes out under your Page's name.
Which route fits your Page
Three routes, and the right one follows from how your Page is actually used rather than from budget:
- Meta's built-ins, free. Occasional messages, and an acknowledgment is genuinely enough. Set it up as above and stop there.
- Keyword flows. The same ten questions at volume: order status, opening hours, booking links. Nobody minds a script for a tracking number.
- Voice-trained AI. The Page carries your name and the reply IS the product. A consultant, a doctor, an agent. A script here reads as absence.
The question is not which tool is best. It is whether the person messaging you expects a company or expects you.
What fast replies do for a Page
Facebook surfaces Page responsiveness to people considering messaging you, and the behavioral effect is bigger than the badge: someone comparing two consultants messages both, and the one who answers first, sounding human, usually gets the call. Automating the acknowledgment is table stakes; automating a genuine answer in your voice is the actual advantage.
