Instagram Automatic Reply to Comments: Moving a Public Comment Into a Private DM

You posted a product, someone commented "price?" under it, and you want an Instagram automatic reply to comments that answers them instantly and moves the conversation into your DMs — without the reply reading like a robot wrote it. The good news: this is exactly what Meta built the comment-to-DM flow for. The bad news: most sellers get the wording wrong, the timing wrong, or the mechanics wrong, and end up with a reply that feels spammy or a DM that lands in the wrong folder.

Here is how to do it properly, what Meta actually allows, and the scripts that work.

What Meta actually allows (and what it does not)

Instagram gives you a few real tools for automatic replies to comments, and you need to know which one you are using.

• Keyword replies in the Instagram app. Available on professional accounts. You pick a keyword (like "price" or "سعر"), and when someone comments that keyword, Instagram automatically sends them a DM with a message you wrote. This is the core tool, and it is what most of this article is about.
• Meta Business Suite automated replies. Similar function, managed from the desktop inbox. Useful if you or a team member work from a computer.
• Third-party automation tools. These connect to your Instagram professional account through Meta's API. They can do more (route to WhatsApp, tag the contact, log the order), but they are still bound by Meta's rules.

What Meta does not allow:

• Auto-replying to every comment, even ones that are not asking anything. This gets flagged fast.
• Sending a DM to someone who did not comment the keyword and did not message you first. That is unsolicited messaging and it will get your account restricted.
• Replying to a comment with a public reply that contains a WhatsApp number, a phone number, or an external link. Instagram hides or flags these.

So the rule is simple: the buyer has to trigger the reply. You cannot push it.

The comment-to-DM flow, step by step

Here is the exact setup, using the Instagram app.

1. Go to your profile, tap the menu, then Settings and privacy → Business tools and controls → Saved replies or Automated replies (the exact label shifts between app versions).
2. Choose Reply to comments.
3. Add a keyword. Use the word your customers actually type: "price", "سعر", "بكم", "details", "متوفر". Add several, one at a time.
4. Write the DM that gets sent when someone comments that keyword.
5. Turn it on and test it with a friend's account or a second account of your own.

A few things that trip people up:

• One keyword per entry. Do not write "price or سعر or بكم" in one field. Instagram treats the whole string as one keyword and it will never match.
• Case and diacritics. "Price" and "price" usually match, but Arabic with and without diacritics may not. Test both forms.
• The DM lands in the person's Message Requests folder if you do not already have a conversation with them. Many people never check that folder. Your DM copy needs to earn the tap.

The wording that does not sound like a bot

This is where most sellers lose the sale. A DM that says "Thanks for your comment! Click here for price." reads like a template and gets ignored.

Write the DM as if you personally typed it. Three rules:

1. Use the person's name. Instagram inserts the username automatically in most setups — use it.
2. Reference the comment. "You asked about the price on the linen shirt" beats "Thanks for your interest."
3. Ask one question. A question pulls them into a conversation. A statement does not.

Here is a DM script you can copy:

> Hi {{username}} — saw your comment on the linen shirt 👋 The price is 450 EGP, and I have it in cream, olive and black. Which colour are you thinking of?

And a second one for a product with sizes:

> Hey {{username}}, thanks for asking about the abaya. It is 780 EGP and I have S, M and L in stock right now. What size do you usually wear?

Notice: no link, no phone number, no "DM us for more info." Just the answer and one question.

The public reply: what to say under the comment

When someone comments the keyword, Instagram can also post a public reply under their comment. Keep it short and human. Two options:

• "Sent you a DM {{username}} 💬"
• "Just messaged you the details 🙌"

The public reply does two things: it tells the person to check their DMs (which they often do not think to do), and it shows other commenters that you respond. Never put the price, phone number, or a WhatsApp link in the public reply. It gets hidden and it trains people to keep asking publicly instead of moving to DM.

If you sell in Egypt or the Gulf and your buyers use WhatsApp, the natural next step is to move from Instagram DM to WhatsApp once the buyer confirms interest. Do not do that in the first automatic DM. Do it after they reply.

What to do when the DM gets ignored

A percentage of people who comment never open their Message Requests. This is normal. Do not send a second DM through the automation — that reads as spam and can get you flagged.

Instead:

• Reply publicly under their comment with a short, friendly nudge a few hours later: "Still interested? The DM is waiting 🙂"
• If they comment again, the automation fires again. That is fine — it is a new trigger.
• If they follow you, you can now message them without the request folder problem. This is one reason following back is a real conversion step.

Common failure modes to avoid

• Keyword too broad. "Hi" as a keyword will fire on every comment and look broken.
• DM too long. More than three short lines and people scroll past.
• No question at the end. The DM becomes a dead end.
• Link in the first DM. Instagram may restrict it, and users distrust it.
• Same DM for every product. If you sell more than one thing, set up separate keyword entries per product so the DM actually matches the comment.
• No human takeover. The automation starts the conversation. A person has to finish it. If nobody is watching the inbox, the reply is wasted.

Where this fits with the rest of your inbox

The comment-to-DM automation handles the first ten seconds. Everything after that — the price negotiation, the size question, the order confirmation — happens in DMs and, for many sellers in Egypt and the Gulf, ends up on WhatsApp. If you are running Instagram, WhatsApp and Messenger side by side, keeping track of which buyer came from which comment becomes its own job. Tools like Co-Social put those channels in one inbox so the comment that started the conversation is still visible when you are closing the order — but the automation itself is something you set up in Instagram today, for free, in about ten minutes.

Start with one keyword and one product. Test it. Then add the rest.
