How to set up auto-reply on Facebook Messenger
Meta's own instant replies cost nothing and take about two minutes. The controls live in Meta Business Suite, and Meta documents the current flow in Set up Inbox Automations on Meta Business Suite. Menu labels shift between rollouts, so the steps below name both layouts still in circulation:
- Open Meta Business Suite and select the Page you manage.
- Go to Inbox, then open Automations. Older layouts label this Automated responses in the left-hand column.
- Choose Instant reply, then Edit.
- Tick where it fires: Messenger, Instagram, or both.
- Write the message, then use Add personalization to insert the sender's first or full name, your Page link, or your website.
- Save, then repeat under Away message so your off hours state an honest return time.
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. Insert the name tokens with the Add personalization button rather than typing them by hand.
- 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.”
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 seven 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.
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.
