Instagram Auto Reply: How to Automate DMs and Comment Replies (2026)
The free ways to send automatic replies on Instagram, Meta’s rules for automated DMs, example messages, and when an AI assistant is the better choice.
For many businesses Instagram DMs are where buyers ask first: "How much is it?", "Do you have it in my size?", "Can I book for Saturday?". This guide covers the free ways to reply automatically, the Meta rules every automation has to follow, example texts, and where fixed replies stop being enough.
Before you start: a professional account
Automated messages need an Instagram professional account (business or creator). Comment-to-DM automations and third-party tools also need the account linked to a Facebook Page and managed in Meta Business Suite. Personal accounts cannot send automated messages.
The free built-in options
| Option | What it does | Automatic? |
|---|---|---|
| FAQs | Shows up to four tappable questions when someone opens a chat with you, each with a prepared answer | Yes, when tapped |
| Saved replies | Stores text you insert with a shortcut | No, a person sends it |
| Instant reply | Sends a fixed reply to the first message in a new conversation (Meta Business Suite) | Yes |
| Away message | Sends a fixed reply while you are away | Yes |
| Comment-to-DM | Sends a DM when someone comments with a keyword you choose (Meta Business Suite) | Yes |
How to set up an instant reply
- Open Meta Business Suite and go to Inbox.
- Open the automations area (often labelled Automations or shown as a lightning icon).
- Choose Instant reply, select Instagram, write the message and switch it on.
Menu names change often, so look for the feature name if the path differs.
How to set up FAQs
In Meta Business Suite automations, or in the Instagram app under the business tools for messages, add up to four questions and an answer for each. People see them as buttons when they open a chat with you.
How to set up comment-to-DM
In Meta Business Suite automations, create an automation triggered by comments: choose the post or reel, the keyword (for example "PRICE") and the DM to send. Usually one keyword per automation. It is useful for posts that end with "comment PRICE and we will DM you the list".
Meta’s rules for automated DMs
- 24-hour window: a business can reply within 24 hours of the person’s last message. Some click-to-message ads give a longer window.
- One private reply per comment: you can send one DM in response to a comment.
- No cold DMs: you cannot send automated messages to people who never contacted you.
- No password sharing: use tools that connect through Meta’s official login, never ones that ask for your Instagram password.
Example auto reply texts
Instant reply, studio > Hi, thanks for your message! Class times and prices are at [link]. Which class are you interested in? We will reply within working hours.
Away message > Thanks for writing! We reply between 09:00 and 19:00. Our price list and frequently asked questions are at [link].
FAQ answer, "How do I book?" > You can book online at [link] or send us the day and time that suits you here.
Comment-to-DM, keyword "PRICE" > Hi! Here is our price list as promised: [link]. Tell us what you are looking for and we will help you choose.
Where fixed replies stop working
- Everyone gets the same text, whatever they asked.
- The real question waits until someone on the team is online, and the 24-hour window keeps running.
- No understanding: built-in tools react to a first message, a tap or a keyword, not to what the person actually wrote.
- No qualification: the inbox does not tell you who is ready to buy.
The next step: an AI assistant
An AI assistant connected through Meta’s Messaging API reads each DM and answers from your own information, asks the next useful question and hands ready buyers to your team, inside Meta’s rules. If people also reach you on your website and WhatsApp, choose one that keeps one conversation per person across channels.
Where Sonic Prospect fits
Sonic Prospect is an AI sales assistant for your website, WhatsApp and Instagram. It answers from your own website, in the visitor's language, and moves serious buyers to the next step, such as a visit, a trial lesson or a booking request. A person who moves between channels stays one conversation and is never billed twice. Setup from your website is free and our team helps connect Instagram and WhatsApp. You pay per qualified prospect: the first 5 are free, then $5.99 each through the first 1,000, then $9.99. Standard conversations (up to 20 answers per visitor a day) are free.

Frequently asked questions
Can I set up an auto reply on Instagram for free?
Yes, with a professional (business or creator) account. Instagram FAQs, saved replies and instant or away replies in Meta Business Suite are free. Personal accounts cannot send automated messages.
Can I send automated DMs to people who never messaged me?
No. Under Meta’s rules a business can reply within 24 hours of a person’s message and can send one private reply to a comment. Cold automated DMs are not allowed.
Is it safe to give an Instagram automation tool my password?
No. Use tools that connect through Meta’s official login and Messaging API. A tool that asks for your Instagram password puts the account at risk.
