You can set up a Facebook Page auto reply for free in Meta Business Suite: open Inbox, then Automations, and turn on an instant reply, an away message, frequently asked questions or keyword replies. For comments, the comment to message automation sends a private Messenger reply. Tools connected to Meta's API add public comment replies, AI answers and spam moderation.
This guide walks through each native option, the Messenger rules that apply to every tool, fixes when replies don't send, and how to tell when you need more.
Which auto replies can a Facebook Page use?
Meta Business Suite groups them under Automations. Here is what each one does:
Automation | What it does | When it fires |
|---|---|---|
Instant reply | Greets people and sets expectations | First message someone sends your Page |
Away message | Says when you'll be back | Messages received during your away hours |
Frequently asked questions | Shows questions people can tap, each with an automated answer | When someone opens a chat with your Page |
Custom keywords | Sends a set answer when a message contains a keyword | Messages that match one of your keywords |
Comment to message | Sends a private Messenger reply to people who comment | Comments on your posts |
Location, contact information, hours | Answers the practical questions automatically | Messages that ask for them |
All of them are free and managed from the same place, as described in Meta's help center on automated responses. Most can also apply to Instagram if your account is connected to the Page.
How to set up a Facebook Page auto reply in Meta Business Suite
Open Meta Business Suite on a computer and select your Page. If you have trouble getting in, our guide to the Meta Business Suite login covers the common issues.
Click Inbox, then Automations.
Click Create automation and choose a template: instant reply, away message, frequently asked questions, custom keywords, comment to message, or one of the practical templates.
Choose the channel. Tick Messenger, and Instagram if you want the same reply there.
Write the message. Use the personalization option to insert the person's first name.
Save and switch it on with the toggle under Status.
Test from a personal account that has never messaged the Page. Instant replies only fire on a first message, so an old conversation won't trigger them.
Instant reply examples
Situation | Example message (fictional bakery) |
|---|---|
General | Hi {{first name}}, thanks for writing to Maple and Crumb! We reply within one business day. For opening hours and our menu, see the link in our bio. |
Orders | Hi {{first name}}! For custom cakes, tell us the date, the number of guests and any allergies, and we'll send a quote within 24 hours. |
Peak season | Hi {{first name}}, December is our busiest month. Messages get an answer within 48 hours; for same-day orders, please call the shop. |
Away message
Set your weekly schedule in the automation, then write a message that says when you'll be back and where to find urgent information. Check the time zone in your Page settings: a wrong time zone is the most common reason away messages go out at the wrong time.
Frequently asked questions
Pick the questions people ask before buying or booking: prices, delivery areas, opening hours, how to order. Each question gets a short answer, ideally with a link. Review them whenever your prices or policies change, because a wrong automated answer is worse than none.
Keyword replies
A keyword automation sends a set answer when a message contains one of your words. According to Meta's help center, an automation takes up to 5 keywords or phrases, matching is case-sensitive, the reply goes out after 15 minutes unless you answer first, and an away message wins if both match. Add the spelling variants people actually type.
How to auto reply to comments on your Facebook Page
The native comment to message automation sends a private Messenger reply to people who comment on your post, for example to send a link to everyone who comments "menu". Meta's private replies rules apply: one private message per comment, sent within 7 days of the comment. If the person answers, the conversation continues in Messenger.
What the native tools don't do is post public replies under the comment, answer open questions in context, or hide spam and scams in your comment section. For that, you need a tool connected to Meta's API. Our guide to auto-replying to Facebook comments covers public replies in detail, and our guide to Facebook auto DMs covers the private side.
Ad comments deserve their own plan: they arrive on posts people can't find on your Page, often in large numbers. Our guide to monitoring comments on Facebook ads explains how to see and answer them.
The Messenger rules every auto reply follows
Rule | What it means |
|---|---|
24-hour window | Automated messages go out within 24 hours of the person's last message |
Human agent tag | A person can still answer up to 7 days after the last message (Messenger policy) |
One private reply per comment | A comment opens one Messenger message, within 7 days |
Conversation starts with the person | Pages can't message people who never contacted them |
These rules apply to Meta's own automations and to every third-party tool, so be wary of any service that promises to message people outside them.
Why your Facebook auto reply is not working
The automation is off. Check the toggle under Status in Automations.
You tested from an account that already messaged the Page. Instant replies only go to first messages.
The away schedule or time zone is wrong. Away messages only fire during the hours set, in the Page's time zone.
The keyword didn't match. Matching is case-sensitive, so add variants, and remember the 15-minute delay.
An AI agent is switched on. Meta notes that turning on its business AI agent can pause existing automations (details).
Your access level is too low. You need access to the Page's messages in Meta Business Suite to create or change automations.
Best practices for Facebook auto replies
Sound like a person. Use the first name, write the way your team talks and sign with a team name.
Set expectations you can keep. "Within one business day" only works if someone actually replies within one business day.
Give something useful right away. A link to your menu, prices or booking page answers half the questions before a human is needed.
Keep automation as the first step. An auto reply acknowledges the message; your team or a grounded AI still has to answer it.
Review every quarter. Prices, hours and policies change, and old automated answers quietly create complaints.
When Meta Business Suite is not enough
Need | Meta Business Suite | Tool on Meta's API |
|---|---|---|
Greeting, away message, FAQ | Yes, free | Yes |
Private reply to comments | Yes, comment to message | Yes, with keyword variants and AI intent |
Public replies under posts and ads | No | Yes |
AI answers grounded in your FAQ | Limited | Yes |
Hiding spam and scams in comments | Manual, plus Page moderation filters | Automatic, in real time |
Several brands and a shared team inbox | Basic | Yes |
If your Page gets a few messages a day, stay native. When comments pile up under ads, when the same questions come back in comments and Messenger, or when spam starts to appear, a tool pays for itself. Our guide to Facebook comment moderation covers the moderation side.
Automate it with Blabla
Blabla connects to your Facebook Page through Meta's official API. It answers Messenger conversations and comments with AI in your brand's tone, grounded in your own FAQ, and a faithful mode reuses your saved answers word for word. It sends a private message when someone comments a keyword, can like comments on your posts automatically, and hides spam, scams and hate in real time, including under ads and dark posts. Everything lands in one inbox your team can share, with a hand-off for sensitive cases. Set it up in Blabla automations and tune the replies in Blabla AI.
The bottom line
Start with the free tools: an instant reply that sets expectations, an away message with the right time zone, a few FAQs and a keyword or two. Add a tool on Meta's API when comments, ads and repeat questions outgrow what one inbox and a few templates can handle.
