Instagram auto DM for affiliate links: "Comment LINK" and the deal lands in their DMs
Post the find, ask followers to comment LINK, and Comment Kro DMs them your Amazon, Flipkart, Myntra, Meesho or storefront link within seconds. It works on Reels, photo posts and carousels alike.
The problem
The challenges affiliate and deal creators face on Instagram
Deals end before you reply
Lightning deals and price drops can be gone within hours. If "link pls" comments wait until you are back online, the price may already have changed.
Links in captions don't work
Instagram doesn't make links in captions or comments clickable, and a link-in-bio page full of old deals makes followers hunt for the one they just saw.
"Link nahi aaya" in the comments
People who don't follow you get the DM in Message requests, miss it and comment again. Explaining this over and over eats into a busy deal day.
Automations
Automations built for affiliate and deal creators
Set one up once and it runs on every matching comment or message.
Comment → one link per deal post
Give each deal post its own automation with "Specific posts" and the keyword LINK. The right link goes out even when several deals are live at the same time.
Comment → every link from a list post
For "under ₹499 finds" or sale-day picks, one DM can carry every product link with a short label for each, up to 2,000 characters.
DM → today's deals page
Put "DM DEALS for today's loot" in your bio. Anyone who sends DEALS gets the link to your deals page, storefront or channel.
Story mention → thanks and your storefront
Followers who post their purchase in a story and tag you get a quick thank-you by DM, along with your storefront link for the next find.

Why Comment Kro
How Comment Kro helps affiliate and deal creators
Built on the official Instagram API, set up without code, and free to start.
- "Specific posts" automations, so every deal post sends its own link even when they all use the keyword LINK.
- Duplicate yesterday's deal automation, swap in the new post and link, and launch it again.
- Switch a deal's automation to Paused once the offer is over, and back to Active if the price drops again.
- A public reply that tells non-followers to look in Message requests.
- Every person who asks for a link is saved as a lead you can tag by category, like kitchen or gadgets.
FAQ
Questions from affiliate and deal creators
Instagram now lets creators add product links to Reels. Do I still need auto DMs?
Use both where they fit. Since March 2026, Instagram lets some creators add product links to Reels, for products that are in a Meta catalogue. A keyword DM still covers the rest: products that aren't in a catalogue, posts with several links, posts where you can't add a product link, and a list of the people who asked.
Kya ek hi post pe Amazon aur Myntra dono ke links bhej sakte hain?
Yes. Put both links in the same DM with a short label, like "Amazon:" and "Myntra:". If you would rather people pick one, ask them to comment AMAZON or MYNTRA and set up a separate automation for each word on that post.
Am I allowed to send affiliate links by DM?
That depends on each affiliate program's terms, not on Comment Kro. Read the rules of every program you use, since some limit where their links can be shared, and label affiliate links clearly, for example with "affiliate link" or #ad.
I post deals all day. Is the Free plan enough?
Free gives you 1,000 DMs a day, with no cap on how many automations you run. If your deal posts regularly need more than that, Pro costs ₹199 a month (or ₹149 a month billed yearly) and removes the daily DM limit. It also adds CSV export of your leads.
