Comment link automation
By Kushagra Kumar, founder of Shre. Updated 1 July 2026.
Shre is an Instagram AutoDM platform that automatically sends a DM when someone comments a keyword on your Instagram posts or Reels.
The classic "comment LINK" call to action, made automatic.
Create an automation in Shre, set the keyword to 'link', and write the DM with your link. Everyone who comments 'link' is DM'd automatically.
The comment link play
Post a reel, tell viewers to comment "link", and let Shre DM the link to each of them. It is the simplest, highest-converting Instagram automation.
Set it up in minutes
- Pick the reel and the word "link".
- Write the DM with your link.
- Turn it on before the reel takes off.
What comment to link automation is
Comment to link automation means a link is delivered automatically when someone comments a chosen word on your post or Reel. You do not paste the link in the comments and you do not reply by hand. Instead, the person gets a private DM with the link the moment they type the keyword. Shre does this on the official Instagram Graph API and never logs into your account.
Why send the link by DM, not in comments
Links pasted in comments get buried, look spammy, and can hurt reach. A DM is private, arrives instantly, and lands in a place people actually check. It also starts a one to one thread you can build on later. This is why comment to DM outperforms a link in the bio that people rarely tap.
How to set it up
- Connect your Instagram professional account
- Pick the post or Reel that will carry the offer
- Choose a short, clear keyword like LINK or GUIDE
- Write the DM that includes your link
- Turn it on and test it from another account
Use cases
Send a lead magnet, a product page, a booking link, a presave, a menu, or a discount code. Anything you would normally tell people to find in your bio can be delivered directly instead. See DM automation for more patterns.
Safety on the official API
Because Shre runs on Meta's official Graph API and paces its sending, it works within Instagram's own system rather than around it. There is no password sharing and no risky third party login. That keeps your account safer than tools that automate by logging in as you. Try it free for 7 days with no card, then a flat 499 rupees a month or 1999 a year with unlimited messages.
