Instagram auto reply: every comment answered, every DM answered, while you sleep. Three kinds of automatic reply, how to set each up, and the messages to copy.

An Instagram auto reply is a message your account sends by itself: a public reply under a comment, a DM to the person who commented a keyword, a welcome message when someone writes to you, or an answer to a question. Instagram's own app covers the simplest cases with saved replies and a few FAQ buttons; it cannot reply to comments by itself or answer a question. SimplyBoost adds the rest: rules that reply to comments and send a DM with your link in seconds, timed follow-ups, and an AI agent that answers the DMs no rule covers, from your own content. Rules from €17 a month, the AI agent from €39.

The three kinds of Instagram auto reply

Auto reply to comments

Someone comments LINK, PRICE or anything at all under a post or reel. A rule posts a public reply under the comment ("Sent you a DM!") and sends the DM with a tappable button. One DM per person per rule per post, so a second comment is not answered twice.

Auto DM and welcome message

The DM a rule sends is your welcome: the link they asked for, a discount code, the price list, a free guide. Ask for an email in it and the first address they send is saved. Up to six follow-ups within 23 hours if they go quiet, stopped the moment they reply.

Auto reply to questions

"Do you ship to Ireland?" "Is the medium back in stock?" An AI agent trained on your website, catalogue and policies answers DMs that no rule covers, in the language the person writes, and hands over to you when someone wants a person.

What Instagram's own app does, and what it does not

Instagram Business and Creator accounts get a few built-in tools in the app. They save typing; they do not reply by themselves.

How to set up an Instagram auto reply with SimplyBoost

Your account must be a Business or Creator profile. Setup is one sign-in through Instagram; there is nothing to install.

  1. 1

    Connect Instagram

    Sign in from the SimplyBoost dashboard and allow it to manage messages and see comments.

  2. 2

    Create a rule

    Choose a keyword, or Anything for every comment. Write the DM, add a button with your link, and decide whether to reply publicly under the comment (on by default).

  3. 3

    Choose where it runs

    Any post, including the ones you publish later, or up to 200 chosen posts and reels. Different posts can run different keywords.

  4. 4

    Add follow-ups and the follow gate

    Up to six messages for people who did not reply, within 23 hours. Switch on Ask non-followers to follow first if you want the DM held until they follow.

  5. 5

    Link an agent for the questions

    On the Agent tab, keep Answer DMs with AI around the clock on. Give it your website, FAQs and policies, and it answers everything a rule does not.

Instagram auto reply messages to copy

Short, in your voice, with one thing to tap. {username} becomes their handle. Eighteen complete rules are on the templates page.

Public reply to a comment
"Sent it to your DMs, @{username} 💌" or "Check your inbox, {username}, the link is there." Short enough that everyone scrolling sees the comment is being answered.
Welcome DM with a link
"Hey {username}, here is the guide you asked for 👇 Tap the button and it is yours. Reply here if anything is unclear, I read every message." Then the button: Get the guide.
Discount code DM
"Thanks for commenting, {username}! Your code SPRING10 takes 10% off this week. Tap below to shop." Button: Shop with my code.
Email ask
"Want the PDF? Reply with your email and I will send it over." The first email they send is saved with their handle and the DM goes out.
Follow-up after a day of silence
"Still here if you have questions about the {product}. The link above works until Sunday." Sent only if they have not replied; one reply stops the sequence.
Handover
"Let me get a person on this. Someone from the team will reply here shortly." The agent sends it when a follower asks for a person, complains or wants a refund, and your team takes over from the inbox.

Instagram auto reply questions

Not by itself. The Instagram app has saved replies and FAQ buttons for DMs, but nothing that answers a comment automatically. A tool connected through Instagram's messaging API, such as SimplyBoost, can reply publicly under a comment and send a DM when a keyword appears.

Connect your Business or Creator account to SimplyBoost, create a rule with a keyword or Anything, write the DM and the public reply, and choose the posts it applies to. It runs the moment you save it. For questions that no rule covers, link an agent that answers from your content.

Yes, through Instagram's official messaging API for Business and Creator accounts. Automated DMs stay inside Instagram's 24-hour messaging window, and anyone who writes STOP gets nothing automated after that.

Instagram's app shows a few FAQ buttons when someone opens a chat with a Business account, with fixed answers. With SimplyBoost, the DM a rule sends is the welcome: the link, code or guide the person asked for, in your words, with a button. The AI agent handles what they ask next.

Yes. Link an agent and keep Answer DMs with AI around the clock on. It answers DMs that no rule covers from your website, catalogue and policies, and hands over to your team when a person is needed.

Rules run on posts and reels, on one, a chosen set or all of them including future ones. Stories are not covered.

Rules and follow-ups start at €17 a month on the Instagram plans, counted in messages with no limit on contacts. The AI agent that answers questions is on the Starter plan at €39 a month with Instagram included. Every account starts with a 7-day free trial.
