How DMback works
You post “Comment GUIDE and I’ll send you the link”. Everyone who comments GUIDE gets a private message from your account within seconds, with your link, discount code or download. You don’t have to do anything.
What is DMback?
DMback is an online tool for Instagram business and creator accounts that automatically sends a direct message (DM) to people who comment a chosen keyword under a post or reel. This is often called “comment to DM”, “auto DM” or an Instagram auto-reply.
It works through Meta’s official Instagram API (the “private replies” feature), the same route the large automation platforms use. You connect your account with Instagram Login, so DMback never sees your password.
There’s no chatbot builder to learn: you choose a keyword, write the message, and you’re done. DMback is made in the Netherlands, stores data in the EU (Frankfurt) and costs from €12 per month per Instagram account.
Step by step
- Connect Instagram
Log in with your business or creator account via Instagram and give permission for comments and messages. It takes one minute.
- Choose a keyword
For example GUIDE, LINK, PRICE or a heart emoji. Use it on one specific post, or on all your posts at once.
- Write your DM
Write the message people receive: a greeting, your link, a discount code. Optionally add a short public reply under the comment, like “Sent you a DM!”.
- Post and mention the keyword
Put the call to action in your caption or reel: “Comment GUIDE”. That’s the only thing you have to remember.
- Everyone gets their DM
Every matching comment gets a DM within seconds, day and night. In the dashboard you see what was sent, to whom and why something wasn’t sent.
What people use it for
Anything where you want people to take one step from a post to your website, shop or mailing list.
Lead magnets
Free guide, checklist, template or e-book: comment a word, get the download link, and you can grow your mailing list.
Product links
Instagram doesn’t allow clickable links in captions. With a keyword, people get the product link straight in their inbox.
Discount codes and launches
Give a personal-feeling discount code to everyone who reacts to your launch post.
Webinars, courses and events
Send the sign-up page for your webinar, workshop, course or ticket sale.
Giveaways
Thank every participant with a DM and the rules, so your comments don’t turn into a pile of unanswered questions.
Price and info requests
Comments like “price?” or “info” get an immediate answer with your price list or booking page.
What’s included
Keywords per post or for all posts
A keyword on one post wins over the same keyword for all posts, so you can send a different link per post.
Forgiving matching
Capitals, punctuation and emoji are ignored. “heart” matches every heart emoji. You can test a comment in the editor before you post.
Never twice, never forgotten
Every comment is stored first and then answered. If something goes wrong, it’s retried without messaging anyone twice. Optionally: one DM per person per post or per day.
Public reply under the comment
Let the account also reply publicly (“Check your DMs!”). That shows others it works, and helps your post’s engagement. (Pro and Agency)
Activity overview and export
See every comment, the matched keyword and whether the DM arrived, with the reason if not. Export to CSV. (Export: Pro and Agency)
Respects Instagram’s limits
Messages are paced so you stay within Instagram’s rate limits, even when a post goes viral.
Connection stays fresh
The connection with Instagram is renewed automatically. If it ever fails, you get an email straight away.
Team and multiple accounts
Invite colleagues, and with Agency manage up to five Instagram accounts in one workspace.
GDPR-proof
Servers in the EU, data processing agreement included, automatic deletion after the retention period you choose.
In your language
The website and dashboard are available in English, Dutch, German, French, Spanish and Portuguese.
Instagram’s rules (and what they mean for you)
These limits come from Instagram itself and apply to every tool that sends automatic DMs:
- Only business and creator accounts can send automatic DMs. Switching is free in the Instagram app and you don’t need a Facebook page.
- Instagram allows one automatic private message per comment, and only within 7 days of that comment.
- People who have turned off message requests from accounts they don’t follow can’t receive the DM. The dashboard shows you who.
- A DM is only sent when someone comments with your keyword themselves. That’s what keeps it allowed, and it’s why people actually read the message.
Who it’s for
Creators and coaches
Share guides, freebies and course links without answering every comment by hand.
Online shops and brands
Turn product posts into clicks with a link in every inbox.
Agencies and social media managers
Run comment-to-DM campaigns for several clients, each with their own account and keywords.
Frequently asked questions
What is an Instagram comment-to-DM automation?
It’s a setup where everyone who comments a specific word under your post automatically receives a private message (DM) from your account, usually with a link. DMback does exactly this, without a chatbot builder.
Is it allowed by Instagram?
Yes. DMback uses Meta’s official Instagram API and its “private replies” feature, and only sends a message when someone comments with your keyword. No passwords, no scraping, no browser bots.
Do I need a Facebook page?
No. You connect with Instagram Login. You do need a business or creator account, which you can switch to for free.
How fast does the DM arrive?
Usually within a few seconds of the comment. During very busy moments, messages are spread out a little to stay within Instagram’s limits.
Does it work on reels and carousel posts?
Yes, on posts, reels and carousels. Comments on stories and live videos aren’t supported by this Instagram feature.
What does it cost?
DMback starts at €12 per month per Instagram account, excluding VAT, with a 14-day free trial. You pay per account, not per contact, so a viral post doesn’t make your bill explode.
Can I use it for my clients?
Yes. With the Agency plan you manage up to five Instagram accounts in one workspace, or you create a separate workspace per client.
