Every comment on your ad is a customer asking "where do I buy this?"
Comment Auto Reply answers them, instantly, with the product link or discount code right in their DMs. "Comment SHOP and I'll send the link" turns a flood of comments into a flood of clicks, day and night, while you sleep.
Flat price, no per-contact fees. A viral product post never spikes your bill.
Turn comments into checkouts
The buying intent in your comment section is already there. These are the jobs Comment Auto Reply does for ecommerce brands.
Send the product link from a comment
Stop typing "link in bio" a hundred times. Someone comments your keyword and the exact product page lands in their DMs, one tap from your store. No detour through a link tree.
Drop discount codes on ad posts
Run "Comment SALE for 15% off." Every commenter gets the code and the link together, in a private DM where nobody is tempted to leave it expiring in the public comments.
Recover sales from the comment section
"Is this still available?" "What sizes?" "Where do I buy?" Those comments are warm buyers slipping away. Auto-reply catches every one with the answer and the link, in seconds.
Comment-to-DM on boosted posts and ads
Comment auto-reply works on ad posts and Reels, not just organic content. The traffic you pay Meta for converts to DMs you own, so your ad spend builds a list instead of just impressions.
A viral product post shouldn't eat its own profit
ManyChat bills by active contact. So the post that sells out your inventory is also the one that spikes your software bill, right when you can least afford the surprise. A single 50,000-comment post can run past a thousand dollars in that month alone.
Comment Auto Reply is flat. Whether a post drives 50 orders or 50,000, your price is the same. Every extra sale stays profit, not overage.

From product post to paid order
No flow builder, no desktop, no developer. You do it from your phone before the post even goes live.
Connect your store's Instagram
Sign in with Instagram's official login, no password sharing. You'll need a Business or Creator account, which is free to switch to and takes about two minutes.
Set the keyword and the DM
Pick the word buyers will comment, like SHOP or SALE, then write the DM with your product link and discount code. Add a follow-gate if you want the sale and a new follower.
Post your ad or Reel
Caption it with the call to action. Every matching comment, organic or paid, gets your link within seconds.
Track the clicks back to revenue
Watch triggers fired, DMs delivered, and link clicks per post. See exactly which product and which ad turned comments into orders.
Questions ecommerce brands ask
The honest answers on safety, ads, and what it costs.
Not when it is done the way Comment Auto Reply does it. Instagram allows an automated DM in response to a user-initiated action, such as someone commenting on your post. That is exactly the comment-to-DM flow. What gets accounts restricted is cold or mass messaging people who never interacted with you, which we do not do. We send through Instagram's official API and stay inside Meta's published rate limits.
Yes. Meta's own documentation supports "private replies": when someone comments on your post, reel, or ad, you may send them one private message in response. Comment Auto Reply is built entirely on this official mechanism, so you are working with Instagram's rules rather than around them.
Yes. Instagram's API only works with a professional account, which means either a Business or a Creator account. Both are free, and switching from a personal account takes about two minutes in your Instagram settings. Personal accounts cannot use comment-to-DM automation from any tool.
For comment-to-DM you can send one private reply per comment, within seven days of that comment. Instagram's API allows up to 750 private-reply calls per hour per account, and the safe practical ceiling most tools work within is around 200 automated DMs per hour. Your plan's monthly limit sits on top of those API rules.
