Send your product link in a DM when someone comments

Short answer: LinkBounce sends your product link in a private Instagram DM when someone comments a keyword you chose on a post or Reel you selected. The match is whole-word, delivery uses Meta’s official Instagram Graph API, and each commenter gets at most one private reply per post. Free includes 500 DMs a month at $0, and nothing sends until you activate the campaign.

Why the DM is the handoff

A caption can only point at one destination at a time, and everyone who visits your profile sees the same thing. A comment keyword can point at one product. The Reel about the workbook sends the workbook URL; the Reel about presets sends the preset URL. The person who asked does not have to hunt through highlights or guess which link you meant.

That is the split: the post is the invitation, the DM is the handoff for the item they named. LinkBounce is built around that split. Each campaign carries the URL you attach, so a different post can deliver a different product without retyping anything into another tool. The preview shows the message before it goes live, and your workspace uses your URLs.

The DM also meets the person where the request happened. They commented because the caption told them to, and a private reply with the URL finishes that instruction. Keep the link out of the public thread: the public reply, if your plan includes one, can say the link is in their inbox.

What “automatically” includes

Automatically means the activated campaign sends the private reply when the keyword matches. It does not mean every comment on your account, forever, from the moment you connect Instagram. You choose the post or Reel. On Creator and Pro you can target All Posts or the Next Post. You choose the keyword. You preview, then activate. Before activation a draft is inert. After activation, a matching commenter gets one private reply on that post.

Link tracking is not on every plan. Creator and Pro include tracked-link clicks, CTR, and a time series; Pro adds campaign comparison and a media breakdown. Free includes basic campaign results. If you need to know which Reel produced the clicks, that is a paid-plan question, and the pricing page answers it with the exact allowances.

Write a DM people can act on

Name the product, give the URL, and stop. A long message is easier to miss in Message Requests, and Instagram does not always place a first message in the main inbox. One product per campaign beats a menu: the person already chose by commenting the keyword, and they should not have to choose again inside the message.

Use the same URL you would send by hand. LinkBounce does not host the file and there is no checkout inside the DM; the link opens the page you already use. If that page needs a password or a coupon, say so in one short line before the URL.

A week of one product

Pick a single URL for seven days. If you sell a workbook, that URL is the only one in the DM and the caption asks for one keyword. Do not rotate three links in the same campaign. After a few days, Creator and Pro can show whether that URL was clicked; Free cannot. If the Reel is still receiving matching comments when you hit 500 sends, Free pauses. That pause is the signal to stop, wait for the next month, or move to Creator at $8. It is not a bill for the extra comments.

Test with a second account before you put the keyword in a caption that is already getting views. Open Instagram DMs and check Message Requests. If the DM is missing, confirm that the campaign is active, that the comment contains the whole word, and that the comment sits on the selected post.

Which post to automate first

Pick the post where the question already repeats in the comments. A tutorial Reel that ends with “the template is in my profile” is a strong candidate: the intent is visible, the product is named, and one URL answers it. A launch post works too, but be ready for volume. Skip evergreen posts with hundreds of old comments until you have tested the flow on something smaller.

Ask one question before you start: can a stranger understand what the DM will contain from the caption alone? If the answer is no, rewrite the caption first. The automation delivers a link; it cannot explain a product the post never introduced.

Tracked clicks and what they tell you

On Creator and Pro, LinkBounce reports tracked-link clicks, CTR, and a time series, so you can see which days produced clicks rather than guesses. Pro also compares campaigns and breaks results down by media. That is enough to decide whether a Reel deserves a second post or a different keyword. It is not a full attribution suite, and it does not claim to follow a buyer past the page you send them to.

Limits that stay in view

One Instagram account per workspace. The account has to be a Creator or Business account connected with Meta OAuth. LinkBounce does not ask for your Instagram password. Saving a draft does not start sending. You activate each campaign yourself. A matched comment gets at most one private reply per commenter on that post. LinkBounce does not scrape profiles and does not message people who never commented.

Free stops at 500 automated DMs in the month. Creator stops at 3,000. Pro removes LinkBounce’s own monthly DM cap, and Meta’s messaging windows and rate limits still apply. Public reply variations are a paid feature: 3 on Creator, 10 on Pro. Link tracking and CTR are on Creator and Pro. Campaign comparison and media breakdown are on Pro.

There is no checkout inside the DM. The link goes to the page you already use. There is no promise about Instagram reach, and no promise that Meta will deliver every message outside its rules. If the second account does not see the DM, check Message Requests before you assume the campaign failed.

When another tool fits better

Other tools also send a link from a comment. LinkDM published 1,000 free DMs a month and multi-account paid plans on 13 November 2026. Hypello published 1,000 free DMs and a $4.90 Creator plan. ManyChat is a wider chat product, and ManyChat bills by monthly active contacts; see manychat.com/pricing for current prices. Those tools are the better choice if you need several Instagram accounts or more channels. LinkBounce is the narrower choice: one account per workspace, whole-word matching, a preview before activation, and a published pause instead of overage. The mechanics of the keyword itself are in the comment-to-DM guide.

Send the product link from a comment

1. Use a Creator or Business account. Switch the account type in the Instagram app. LinkBounce needs an eligible Creator or Business account for Meta OAuth; a personal account cannot run this automation.
2. Connect through Meta OAuth. Connect Instagram in the workspace and approve the permissions on Meta’s own screen. LinkBounce never asks for your Instagram password. Every plan includes 1 Instagram account.
3. Choose one post or Reel. Pick the post or Reel that should listen for the keyword. On Creator and Pro you can also target All Posts or the Next Post.
4. Name the product and the URL. Pick one product and the exact URL that should be delivered. Different campaigns can carry different URLs, so a workbook Reel and a presets Reel do not have to share a destination.
5. Set a whole-word keyword. Tell viewers to comment a single word such as LINK, then set that word as a whole-word match. Lookalike words that contain the letters do not fire the DM.
6. Write the DM and preview it. Name the product, add the URL, and keep the message short. Run the preview to see exactly what will be sent before anything goes live.
7. Activate the campaign. Drafts do not send. Nothing sends until you activate. Activate only when the post, the keyword, and the URL are final.
8. Test from a second account. Comment the keyword from another account you control. Check Instagram DMs and Message Requests, confirm the URL, then remove the test comment. Meta allows one private reply per comment.

What it costs

LinkBounce has three USD plans, billed for paid workspaces by Dodo Payments. Free is $0 with 500 automated DMs per month, 1 active automation, and 1 Instagram account, no credit card. Creator is $8/month or $80/year: 3,000 DMs per month, 10 active automations, 3 public reply variations, All Posts and Next Post targeting, and tracked-link clicks with CTR. Pro is $14/month or $140/year: unlimited monthly LinkBounce DMs subject to Meta’s limits, 50 active automations, 10 public reply variations, and campaign and media breakdown. Every plan includes 1 Instagram account. Free and Creator pause at the allowance, and there is no automatic overage.

Meta's rules, from the source

Meta’s private replies documentation states: “Only one message can be sent to the commenter”. The private reply must be sent “within 7 days of the creation time of the comment”; for Instagram Live, it can only be sent during the broadcast. Follow-up messages are allowed only if the person responds, and must be sent within 24 hours of that response.

The Instagram Messaging API documentation describes the standard messaging window: “For most user actions, it lasts 24 hours”. These are Meta’s platform rules. LinkBounce’s workflow is a keyword comment on a selected post or Reel followed by at most one private reply per commenter per post.
