How do you deliver a lead magnet from a Reel comment?

Trigger on the comment, private reply with a button to the file, and tag the contact so you know where the lead came from.

The end to end shape:

1. Comment trigger on your Instagram account, keyword GUIDE, post filter set to that Reel. The post filter is what stops the same automation firing on an unrelated post six months later.
2. Private reply with one sentence and a button. If the file lives behind an email gate, the button goes to the page, not the PDF.
3. Public reply so the comment thread shows a response. Vary the wording across two or three lines.
4. Add a tag naming the Reel. This is the step people skip and then cannot answer which post produced the leads.

If you want the email address rather than just the click, ask for it inside the conversation instead of sending them to a landing page. One question, one field, then deliver. Fewer people drop out of a chat than out of a form, and the address arrives attached to a contact that already has the source tag on it.

Two limits worth knowing before you build. A private reply is allowed only within seven days of the comment, so the backlog of two hundred may include comments that can no longer be answered that way. And if the person does not follow you, your reply lands in their Requests folder, so tell them to check there in the public reply.
