Yes. Instagram has auto reply built in, and it is free. Meta Business Suite's Inbox carries a template called Auto reply, plus away messages, custom keywords, and a comment-to-message automation. Instagram's own app adds up to four frequently asked questions with automated answers. Meta's documentation puts a 15-minute delay on keyword replies.

That last sentence is why this question gets answered badly. Most results say either "no, you need a tool" or "yes, just use Business Suite" — and both are half true. Instagram's native auto replies are real and worth setting up. They also have four specific edges that decide whether they are enough for what you want. Every quote below is from Meta's own pages, read on 2026-08-09.

What auto replies can Instagram send on its own?

Instagram's automated replies live in two different products, and knowing which one you are in explains most of the confusion.

Meta Business Suite Inbox is where the real automation sits. Meta describes Inbox automations as "a way to quickly respond to people who message your business across Messenger, Instagram and WhatsApp." The templates it offers:

  • Auto reply — "reply with a greeting when someone messages you for the first time." (The overview page calls the same template Instant reply; the setup page calls it Auto reply.)
  • Away message — "reply to a message when you're not available."
  • Frequently asked questions — "suggest questions that someone can ask you and reply with helpful information."
  • Location, Contact information, Hours — each answers a message asking for exactly that.
  • Custom keywords — "reply to a message that contains specific keywords."
  • Comment to message — "send a message reply to comments on your posts that contain specific keywords or phrases."
  • Identify unanswered messages, and Assign admins for routing.

The Instagram app carries a smaller, separate feature: frequently asked questions in Chats. Instagram's page describes it as a way "to help jump-start conversations with people on Instagram," where "you can select up to four questions to be displayed" and "you can also include automated responses so that people can immediately get answers to simple questions."

These are two different systems with two different setup paths, and turning one on does not turn the other on.

How do you set up auto reply on Instagram?

There are two routes, depending on which of the above you want.

In Meta Business Suite, on desktop: go to Inbox, click Automations, click Create automation, pick the template, and complete the on-screen steps. Meta notes the automation "may take a few minutes to appear." Each one has a toggle under Status, so it can be switched off without being deleted.

In the Instagram app: tap Messages, then Tools, then Frequently asked questions. Turn on the "Show questions" toggle, then Add question — each question takes an optional automated response. Four is the maximum.

One thing worth knowing before you start: keyword automations cannot be created on a phone. Meta states plainly that "keyword automations are only available on the Meta Business Suite desktop experience at this time." If you have gone looking for keyword replies in the mobile app and concluded Instagram does not have them, that is why.

Can Instagram auto reply to a comment?

Yes, through the Comment to message automation in Meta Business Suite — with the same desktop-only restriction as custom keywords.

Meta's two pages describe its trigger slightly differently, and the difference matters enough to name rather than smooth over. The setup page says it replies to comments "that contain specific keywords or phrases." The overview page says it replies to "a comment that contains specific hashtags." Both were read on 2026-08-09. If your automation depends on matching a plain word rather than a hashtag, test it on a real post before you build a campaign on it.

What the native comment automation does not do is bind to one specific post. That is the practical difference from a comment-to-DM tool built on Meta's API, where the automation is attached to the individual reel or post you choose, and a keyword only fires there.

Why does an Instagram keyword auto reply take 15 minutes?

Because Meta built in a pause for you to answer first. Its wording: "Inbox will automatically send a keyword automation to a message after 15 minutes unless you personally respond before then."

Read as a design decision, that is reasonable — it stops a robot talking over a business owner who was already typing. Read as a growth mechanism, it is the single biggest gap between native auto reply and an API automation. Someone who comments asking for your link has moved on well before minute fifteen.

Two more edges on the same feature, both from the same page:

  • Keywords are case-sensitive. "Note that keywords are case-sensitive, and an automated message will not be sent unless the keywords match exactly." Someone who types link when you set LINK gets nothing. (Tools built on the API generally match case-insensitively — inDM does.)
  • Five keywords per automation, and "the same keyword or phrase can only be used in one keyword automated response."

Why did my Instagram auto reply not send?

Three documented reasons, before you go looking for a bug.

A template automation outranks your keyword. Meta: "When both a custom keyword automation and a template automation are turned on and triggered, we'll send the template response but not the custom keyword automated response." Their own example is an away message swallowing a keyword reply. If you left an away message on from a holiday, it is quietly answering everything.

Meta Business Agent pauses everything. "If you turn on Meta Business Agent, any existing automations (such as away messages or instant replies) will be paused."

The reply may be waiting in Requests. For the Instagram app's frequently asked questions, Instagram states: "If a person selects one of these questions, their message will go to your Requests in Chats. You'll need to accept their message request in order to reply to their question." An answer that needs you to accept a request first is not really an automated conversation.

If none of those is it, the causes specific to third-party tools are a different list — that is Instagram DM automation not working.

How do you change, turn off, or remove an Instagram auto reply?

For Business Suite automations: Inbox, then Automations. Every automation has a toggle under Status to turn it off, and an Edit control to change the message. Meta's own instruction is that you "can edit and turn off Inbox automations at any time by going to your Inbox."

For the Instagram app's frequently asked questions: Messages, then Tools, then Frequently asked questions. Tap a question to edit or delete it, then Save.

For Instagram's suggested questions — the four Instagram writes for you based on your account category, which appear even if you never set any up: go to your profile, tap Menu, then Business tools and controls, then Frequently asked questions, and turn off "Show questions" (Android) or "Show questions in chat" (iOS).

That third one catches people out. If your account is answering with questions you never wrote, they are Instagram's suggestions, not an automation you forgot about.

Do you need a business account for Instagram auto reply?

It depends on which feature, and Meta's pages are not identical on this point.

For the Instagram app's frequently asked questions, Instagram is explicit: "This feature is only available for business and creator accounts on Instagram." A creator account qualifies.

For Meta Business Suite Inbox automations, the overview page lists what is supported as "Facebook Pages, Instagram business accounts and WhatsApp Business accounts connected to Meta Business Suite." The setup page says only "your Facebook Page, Instagram account or WhatsApp Business account." One names business accounts specifically and the other does not, and neither mentions creator accounts. We are not going to resolve that from the outside — if you run a creator account and Inbox automations matter to you, check whether the Automations panel appears for your account before planning around it.

What does an automation tool add?

Three things the native tools do not do, and it is worth being precise about which.

It answers in seconds, not after fifteen minutes. Meta pushes a webhook the moment a comment lands, so a tool built on the Instagram API can send a private reply while the person is still on your post.

It attaches to a specific post. A keyword can mean one thing on Tuesday's reel and something else on Friday's, because the automation is bound to the content rather than to the account.

It reports on itself. Which post, which keyword, how many people, where they dropped out. Business Suite's automations run; they do not really tell you how they did.

What a tool does not do is escape Instagram's rules, because it runs on the same platform. It still cannot message someone who has not messaged you first, it still has 24 hours to reply, and it is still bound by Instagram's DM limits — 750 private replies an hour per account. The mechanics are in how Instagram DM automation works.

Where this stops working

Four honest boundaries, including two that apply to us.

  • No auto reply reaches someone who has not contacted you. Native or third-party, the platform rule is the same: a message, a comment, or a story reply has to come first. There is no auto reply to a new follower, because Meta publishes no follower webhook at all — the full field list is in auto-DM new followers.
  • Automated replies have to say they are automated. Instagram's page on automated chats states that "where legally required, these automated chats must tell you when you're interacting with them" — at the start of a conversation, after a significant lapse of time, and when a conversation passes from a human back to an automation. Worth knowing before you write a greeting in your own voice.
  • Availability is not uniform. Meta's setup page carries a notice that certain organic messaging features "for businesses and ads delivered to and from Europe and Japan will be unavailable." If you are in one of those regions, read the panel rather than this page.
  • Everything here has a date on it. All quotes were read on 2026-08-09, from Instagram's Help Centre and the Meta Business Help Centre. Meta changes both without notice, and the two pages already disagree with each other about hashtags. If a decision turns on one of these sentences, go and read it.

What this changes for you

If you want your account to greet a first-time DM, post your hours, or hold the fort while you are away, Instagram already does that and it costs nothing. Turn it on before you buy anything.

If what you want is for someone who comments a word on your reel to get your link while they are still looking at it, that is a different job — and the fifteen minutes is the reason it is a different job.
