What is comment-to-DM?
Comment-to-DM is answering a comment on your post with a private message to the person who wrote it, so details such as prices or bookings move out of public view.
Also called: Private reply.
In plain words
Comments are where many sales start. Someone writes "how much?" or "do you ship to Ireland?" under a post. Answering only in public works, but a comment thread is a poor place to talk about sizes, addresses or appointment times.
A private reply moves the conversation into DMs. Many businesses do both: a short public reply so other readers see the question was answered, and a private message with the real detail and a next step.
Platforms limit this, and a private reply is only possible when the platform allows it for that comment. Flow tools often send a set message when a comment contains a keyword, which suits giveaways. An AI agent can read what the person actually asked and answer it.
Whichever you use, keep the private message relevant to the comment. Someone who asked about delivery wants the delivery answer, not a discount code for something else. A reply that answers the question and offers one clear next step, such as a link to book or a question about their size, tends to turn a comment into a sale.
How it works in Spaces
On Instagram, Spaces covers DMs, comments on your posts, and a private reply from a comment into a DM when the platform allows it. Your agent can read comments, answer them in public and send the private reply.
Spaces routines can also reply to a keyword in a comment with a set message you wrote and message the commenter once. Routines are not an AI, so they suit simple campaigns while the agent handles real questions. Every reply follows the Instagram limits.

- Instagram message requests: Instagram message requests are a separate folder where first messages from people you do not follow usually land, instead of your main inbox.
- Routine: A routine is a rule that runs on its own, on a schedule or when something happens, such as sending a set reply when a message with a keyword arrives.
- New conversation: A new conversation is a message you send to someone who has not written to you in that chat yet, as opposed to a reply in a conversation the other person started.
- Pacing: Message pacing means leaving a gap between messages and capping how many go out in an hour and a day, so an account sends at a speed a person could.
