DM request
Why it matters for creators
The requests folder is where most unsolicited messages quietly die, and understanding that explains a lot about why DM automation works the way it does.
For messages you receive, it is a filter worth actually checking. Real inbound (someone asking about your offer, a genuine enquiry) lands in requests routinely because they do not follow you yet, and Instagram gives it no notification weight. Accounts that only read their main inbox miss the exact conversations they most wanted.
Brand collaboration requests are a common example: how to tell real Instagram collab messages from scams.
For messages you send, it is the reason cold DMs do not work even when a tool can send them. A cold message lands in a stranger's requests folder alongside everything else, unread and unannounced.
An automated reply to a comment is not exempt from this, and it is worth being exact about what decides where it lands. Meta's own documentation says a private reply appears in the person's inbox if they follow the account, and in the request folder if they do not. Following is the test, not commenting. So a reply to a comment from somebody who already follows you arrives where they will see it, and the identical reply to somebody who does not follow you goes to the same folder a cold message would.
This is a large part of what a follow gate is actually buying, and it is a reason to read your delivery numbers rather than assume the message was seen.
