Definition
What is Instagram comment-to-DM automation?
Instagram comment-to-DM automation sends a private DM to anyone who comments a chosen keyword on your post, Reel or Live.
IGMsg delivers your message, link and button through Instagram's official Messaging API in under 3 seconds, saves the commenter as a lead, and sends one DM per person. Part of IGMsg's Instagram automation toolkit.
How it works
Comment to DM in four steps.
- 1
Connect Instagram
One-click, password-free connect for your Instagram Business or Creator account. Takes 30 seconds.
- 2
Pick a post and keyword
Choose any post, Reel, or Live. Set trigger keywords like "LINK" or "GUIDE" - exact, contains, or any comment.
- 3
Write your DM
Add your message with the @username variable and a tappable button. Add variants to stay natural.
- 4
DMs send automatically
Every matching comment fires an instant DM plus an optional public reply. Track sends and clicks live.
Manual vs automated
Why creators switch to comment-to-DM.
| Compare | Replying manually | With IGMsg |
|---|---|---|
| Speed | Hours later - or never | Under 3 seconds, 24/7 |
| Scale | You burn out after ~50 DMs | Hundreds per hour, fully automatic |
| Link clicks | Buried in a wall of comments | Tappable button inside the DM |
| Lead capture | Manual copy-paste, leads slip | Every commenter saved + deduped |
| Account safety | Copy-paste bots risk a ban | Official Meta Messaging API |
| Cost | Your time, every single day | Free plan with 500 DMs/month, then from $7/mo |

Features
Built for comment-to-DM, done right.
Keyword match modes
Exact match, contains, or reply to every comment. Multiple keywords per automation, full control.

Public comment replies
Auto-reply publicly so commenters know to check their inbox - beats the "Message Requests" folder.
Message variants
Add several versions of your DM; IGMsg rotates them so a viral post never looks robotic.

Each user gets one DM per automation, no matter how many times they comment. No accidental spam.
Hourly reply cap
Set a per-hour limit (up to 200) to stay well inside Meta's safe sending range on big posts.
Followers-only filter
Optionally DM only people who follow you and skip everyone else.
Personal touch
Drop the commenter's @username into any message so every DM feels written for that person.
Real-time analytics

FAQ
Comment-to-DM questions.
Straight answers before you switch on your first automation.
Instagram comment-to-DM automation automatically sends a private direct message to anyone who comments a chosen keyword on your post, Reel, or Live. The moment a matching comment appears, IGMsg delivers your pre-written DM - text, links, and a tappable button - through Instagram's official Messaging API, usually in under 3 seconds.
Yes. Replying privately to a public comment is an officially supported feature of Instagram's Messaging API (the Private Replies endpoint). IGMsg never logs into your account or uses bots - it connects through Meta's OAuth and uses only sanctioned endpoints, so your account stays fully compliant.
Under 3 seconds end-to-end. Instagram pushes the new-comment event to IGMsg by webhook almost instantly, and we dispatch the DM immediately after checking your keyword and deduplication rules.
Instagram caps every tool at 750 private replies per hour per connected account. IGMsg's free plan includes 500 DMs/month, Pro includes unlimited DMs, and Business includes unlimited DMs. If a post goes viral, extra messages queue and send in the next window.
Yes. Choose exact-match (only "LINK"), contains-match ("send me the link"), or respond to every comment. You can set multiple keywords per automation and a public comment reply so commenters know to check their inbox.
Yes. Every DM supports text, emojis, the commenter's @username, and a tappable call-to-action button (title + URL) - far higher click-through than dropping a raw link in the comments.
IGMsg deduplicates automatically: each Instagram user receives at most one DM per automation, no matter how many times they comment.
Yes. Any post type that accepts comments - Reels, photos, carousels, and Live replays - works with comment-to-DM automation.
Connect your Instagram Business or Creator account to IGMsg, pick the post or Reel, type the keyword (for example LINK), write the DM with a button, and switch it on. From then on, everyone who comments the keyword gets the DM automatically. It takes about two minutes on the free plan.
One short word that names what people get - LINK, PRICE, INFO or GUIDE are the classics. Use contains-match so comments like "link please" or "send the guide" still trigger the DM, and add emoji or other-language versions your audience types.
As long as it's switched on. The first hours after posting bring the most comments, but posts keep collecting them for weeks from Explore, search and shares - so switch the automation on before you post and leave it running.
