On this page
- Comment to DM sends a private message to anyone who comments your keyword.
- You need an Instagram professional account and a tool on Meta’s official API.
- One clear keyword, said on screen and in the caption, beats a clever one.
- Instagram only lets tools reply to comments made after the automation is on.
What comment to DM is
You post a reel and ask people to comment a word, like LINK. Everyone who does gets a DM with the link a few seconds later. You don’t touch your phone.
It works because commenting is easier than finding a link in your bio, and the DM arrives while they still care. Each comment is also a signal to Instagram that people want to talk about the post.
What you need first
- An Instagram Business or Creator account. Switching is free in Instagram’s settings, and you don’t need a Facebook Page.
- A tool that uses Meta’s official messaging API. Avoid anything that asks for your Instagram password.
- The link you want to send, and one keyword.
Set it up in three steps
1. Pick the posts
Choose the reel or post. You can pick several at once if they share the same freebie.
2. Pick the keyword
Short, easy to spell, and specific to this post. Capital letters don’t matter, and emoji work too. If you’d rather answer everyone, you can reply to every comment instead.
3. Write the DM
Write it the way you’d text a friend. Add a button with your link, and a short public reply under their comment so other viewers can see that commenting works.
Captions that get comments
The keyword has to be impossible to miss. The pattern that works is simple: say it in the video, show it on screen, and repeat it in the first line of the caption.
- “Comment GUIDE and I’ll send you the full checklist.”
- “Want the recipe? Comment RECIPE and it’s in your DMs.”
- “Comment LINK for the exact preset I used.”
Promise something specific. “The 12 shots I use for every product video” gets more comments than “my tips”.
Mistakes to avoid
- Two tools on one keyword. People get two DMs. Turn the old automation off before you switch.
- A keyword people type anyway, like “love” or “wow”. Everyone gets a DM they didn’t ask for.
- No keyword on screen. Most viewers watch without reading the caption.
- Sending people to a page that doesn’t load fast on a phone. The DM is quick; the page should be too.
Questions
Is comment to DM against Instagram’s rules?
No, when it runs on Meta’s official API. Meta built private replies to comments for exactly this. Tools that log in with your password are the risky kind.
Does it work on comments left before I set it up?
No. Instagram only lets tools reply to new comments. Turn the automation on before you post, or before you ask people to comment on an older post.
How much does it cost?
DMChat is free for 1,000 DMs and 5 automations a month. Influencer removes the limits.
