Instagram Story Reply Automation: Auto-DM Story Replies and Mentions (With 10 Ideas)

Automatically DM people who reply to or mention your Instagram story. How story automation works, setup steps, 10 story campaign ideas and the rules to follow.

By the MizUp team · · 3 min read

Story reply automation sends an instant DM when someone replies to your Instagram story, either with any message or with a keyword you choose. It can also react when someone mentions you in their own story. Because a story reply is already a DM, the chat starts privately. That makes stories the easiest place to start conversations with people who already follow you.

Reels vs stories: use both

Three story triggers

  1. Any story reply. Everyone who replies gets the DM. Good for "Reply 🔥 for the link".
  2. Keyword story reply. Only replies containing "BOOK" or "SIZE" get the DM. Cleaner leads.
  3. Story mention. Someone tags you in their story, and you send a thank-you, coupon or review request.

Setup in 4 steps

  1. Connect your professional account through the official Meta login.
  2. Create a story trigger and choose "any reply" or a keyword.
  3. Write the DM: name, one line of value, one button.
  4. Post the story with a clear sticker or text, e.g. Reply "SIZE" for the size chart.

10 story campaign ideas that work in India

  1. Restock alert: "Reply BACK to get the link when it's live."
  2. Festive catalogue: "Reply DIWALI for this year's gift boxes."
  3. Size chart: "Reply SIZE." This cuts returns.
  4. Booking slots: "Reply BOOK for this week's free slots" (salons, clinics, coaches).
  5. Free guide: "Reply GUIDE for the PDF."
  6. Price on request: "Reply PRICE." Useful for real estate and B2B.
  7. Poll follow-up: People who vote get a DM with the matching product.
  8. Webinar reminder: "Reply REMIND."
  9. Mention thank-you: Auto-DM a 10% code to customers who tag you.
  10. Review request: After a mention, send your Google review link.

Rules to remember

  • You can message within 24 hours of the person's story reply.
  • Keep it to one link and a question. Their answer keeps the window open.
  • Don't send repeated promos to the same person every day.

Frequently asked questions

Can I automatically reply to Instagram story replies?

Yes. With a DM automation tool on the official Instagram API, you can send an automatic DM when someone replies to your story, replies with a keyword, or mentions you in their story.

Why use story replies instead of Reel comments?

Story replies are already private messages, so the conversation starts in the inbox. They work well with your existing followers, while Reel comments reach new people.

Can I thank people automatically when they mention me in a story?

Yes. Story mention triggers can send a thank-you DM, a discount code or a request for a review.

Is story reply automation free?

Instagram does not offer it natively. Many tools include it only in paid plans. MizUp includes story triggers from the ₹99 Starter plan.
