Comment to DM on Instagram
By Kushagra Kumar, founder of Shre. Updated 1 July 2026.
Comment to DM automatically sends your link in a direct message to everyone who comments a keyword on your Instagram posts or Reels. Shre runs it on Instagram's official Meta Graph API, so it never needs your password.
It is the simplest way to turn a viral moment into leads: someone comments, they get your link in their inbox within seconds.
It means an automation sends a direct message to anyone who comments a specific keyword on your Instagram post or reel.
What is comment to DM?
Comment to DM is an automation that watches your post or reel for a keyword in the comments and replies to each person with a direct message. It is the core of Instagram AutoDM.
Set up a comment-to-DM automation
- Choose the post or reel to watch.
- Set the keyword, for example "link" or "ebook".
- Write the DM with your link.
- Shre sends it automatically to everyone who comments.
Popular comment-to-DM examples
Creators ask followers to comment a word, then Shre delivers the matching link: "Comment LINK for the guide", "Comment PRICE for the menu", "Comment COURSE to enrol". Each keyword can send a different DM and link.
Comment to DM vs link in bio
A link in bio asks the viewer to stop watching, tap your profile, find the link and remember why they came. Comment to DM meets people where the interest is, in the comments, and puts the link straight in their inbox. Here is how the two compare.
| Link in bio | Comment to DM | |
|---|---|---|
| Where the link lands | Your profile page | The viewer's inbox |
| Steps for the viewer | Leave the post, tap profile, find link | Type one word |
| Works from a Reel or post | Only after they leave it | Yes, without leaving |
| Starts a conversation | No | Yes, opens a DM thread |
| Captures who was interested | No | Yes, every commenter |
The two work well together: keep your bio link for browsers, and use comment to DM to catch the people who are ready to act right now.
Frequently asked questions

Yes. Each automation watches a post and keyword, and sends its own DM and link.

Is comment to DM against Instagram's terms of service?
No. Shre sends messages through Instagram's official Meta Graph API, which Meta approves for replying to comments and DMs on your own account. It is not a bot that logs into your account, so there is nothing against the terms of service.
Do I need to give Shre my Instagram password?
No. You connect through Instagram's official login, so Shre never sees or stores your password and cannot log in as you. You can revoke access from your Instagram settings at any time.

Usually within seconds. Sending is paced to stay inside Instagram's limits, so on a viral post replies go out steadily rather than all at once, which keeps your account safe.
