What is an Instagram auto DM?
An Instagram auto DM is a direct message sent automatically when someone interacts with your account. The most popular version is comment-to-DM: you ask people to comment a word like “PRICE” or “GUIDE”, and everyone who does gets the link in their inbox within seconds.
It works because the DM lands where people already are, it feels personal, and it moves the conversation somewhere you can follow up. Creators use it to deliver freebies, coaches to book calls and brands to answer “price?” at scale.
Triggers FandomFlow supports
Every automation starts with a trigger. You can run several at once and set priorities when they overlap.
- Comments on any post or one specific reel — match any of your keywords, all of them, or every comment.
- Comments on ads — reply on every ad or one specific ad (see ad comment automation).
- DM keywords — answer common questions like “price”, “size” or “shipping”.
- Story replies — respond to everyone who reacts to a story.
- Facebook Messenger — the same flows for your Facebook Pages (Messenger automation).
Built to stay within Instagram’s rules
FandomFlow uses Meta’s official Instagram API with Instagram Login. Automations only message people who interacted with you first — by commenting, sending a DM or replying to a story — and sends are paced per account so you stay within Instagram’s limits.

From DM to sale, without extra tools
Most auto DM tools stop at the message. FandomFlow keeps going: send product cards from your store in the DM, take the payment with UPI on your own domain, and see which automation made the money in analytics. Conversations that need a person land in a shared inbox for your team.
