Instagram DM marketing that turns comments into customers
Ask followers to comment a keyword and IotaBot DMs each of them your link, price or code. Every reply after that is answered by AI from your own content — and warm leads go to your team.

- Per-post rules
- Official Instagram API
Instagram DM marketing with IotaBot: at a glance
IotaBot can send a DM to everyone who comments on an Instagram post, using rules you set per post.
A rule fires on exact keywords, on an AI-matched intent such as “asking about price”, or on every comment.
Each person gets one automated response per post, however many times they comment.
Instagram announcements go to people who messaged you in the last 24 hours; Meta does not allow messaging a list.
Meta caps automated DMs at 200 per hour per account; IotaBot queues the excess instead of dropping it.
IotaBot uses Meta’s official Instagram messaging API.

Instagram DM marketing: frequently asked questions
Still have a question? Talk to us or try the live demo.
Can I send a DM to all my followers?
No — Meta does not allow messaging followers who have not contacted you. You can DM people who comment on your posts, and send announcements to people who messaged you in the last 24 hours.
Is comment-to-DM automation allowed by Instagram?
Yes, through Meta’s official API, which IotaBot uses. Meta limits automated DMs to 200 per hour per account; IotaBot queues anything beyond that for the next hour.
Do I need a business account?
Yes, an Instagram Business or Creator account. Personal accounts cannot use Meta’s messaging API.
Do I need to train an AI to use comment rules?
No. Keyword rules with fixed replies work on their own. The AI is used for DMs and for comments you choose to escalate.
