Send something specific, fast to use and tied directly to the post that triggered it. A one-page checklist that solves the exact problem in your Reel will outperform a 40-page ebook that sort of relates to it.
You've seen the move: "Comment GUIDE and I'll DM it to you." It works because the freebie lands in someone's inbox at the exact moment they raised their hand. But the freebie still has to be worth the comment. If you're a business owner trying to turn Instagram attention into an email list, booked calls or sales, the lead magnet is where that starts. Here's how to choose one, which formats actually work inside a DM, and how to deliver it with Planoly Automations.
What Makes a Good DM Lead Magnet?
1. It solves one problem from the post. If your Reel shows three ways to style a linen shirt, the lead magnet is a styling cheat sheet for that shirt, not your whole lookbook.
Why it works: The person commented because of that post. The closer the freebie is to the post, the more likely they open it and use it.
2. It's usable in five minutes. Checklists, templates, scripts, short audio, a recipe card. People are on their phones. Make it something they can use right there.
Why it works: A quick win builds trust fast, which is what makes the next message (your offer) welcome instead of pushy.
3. It's worth the effort of asking. The author of Buffer's DM automation guide said their best performers were "a Notion database of remote-work resources" and "my CV template," with a simple rule: "whatever you're sending has to be worth the follow." Swap "follow" for "comment" and the rule still holds.
Why it works: Asking someone to comment is a small favor. A generic freebie makes the favor feel wasted.
Lead Magnet Ideas That Work in a DM
Here are formats that fit a DM, matched to the message type Planoly Automations can send. Every limit below comes from Planoly's help article.
| Lead magnet | Good for | Planoly message type |
|---|---|---|
| Checklist, guide or worksheet | Coaches, service providers, educators | PDF (up to 25MB) |
| Recipe card or how-to graphic | Food, wellness, home and beauty businesses | Media: photo (JPEG or PNG up to 8MB) |
| Short tutorial or walkthrough | Product businesses, software, salons | Media: video (MP4, MOV or WebM up to 25MB) |
| Personal voice message or mini lesson | Coaches, consultants, wellness practitioners | Voice note (up to 5 minutes, one per automation) |
| Template, free class or discount page | Anyone sending people to a web page | Card (picture, title, description, link, up to 3 buttons) |
| Product roundup or gift guide | Shops, affiliate links, multi-product launches | Gallery (up to 10 cards) |
One more limit to plan around: photos, videos and PDFs across all of an automation's messages add up to 5 at most. And each automation can hold up to 10 messages, sent in the order you set.
A real-world example: one doula on Reddit described asking followers to "comment NOURISH" for a meal train guide, adding, "If you have 200 followers and are wondering how to turn that into actual consult calls, this is how." Small account, specific freebie, clear next step.
How Do I Get the Email Address?
Send people to a sign-up page. The simplest setup: put the lead magnet behind a short form on your website or email tool's landing page, then deliver that link in a card. The card shows a picture, a title and a description (80 characters each for title and description) with a button that opens the page.
If you'd rather deliver the freebie instantly in the DM (a PDF, say), add a follow-up card that offers something extra in exchange for an email: "Want the full 30-day version? Grab it here."
Why it works: Delivering the freebie first and asking for the email second keeps the promise you made in the caption, then gives people a reason to opt in.
Planoly's plans also include a link-in-bio page where you can sell digital products with zero transaction fees, which gives your DM a natural place to point when the next step is a paid product.
What Results Are Realistic?
Honest answer: the published numbers mostly come from tool vendors and their best customers. ManyChat's case study on educator Amy Porterfield reports that a free masterclass delivered by DM produced 3,243 sign-ups. That's vendor-reported, from someone with a large audience and a proven offer. Use it as proof the mechanic works, not as a benchmark for your account.
The better benchmark is your own: run one lead magnet on one post, then compare it with your next one.
How Do I Measure It?
1. Check Sent and Opened in Planoly. Sent is the people your automation answered; Opened is the people who read the DM or tapped its button. Planoly doesn't track link clicks, so step 2 matters.
2. Track sign-ups on your landing page. Use a dedicated sign-up page (or a tagged link) per lead magnet so you know which post drove which emails.
3. Compare lead magnets, not posts. Run two different freebies on two similar posts and see which earns more sign-ups per comment.
Why it works: DM numbers tell you delivery is working. Sign-ups and sales tell you the freebie is.
Frequently Asked Questions
What is a good lead magnet for Instagram?
Something specific to the post, usable in a few minutes, and valuable enough to justify the comment. Checklists, templates, short videos and recipe cards all work well.
Can I send a PDF in an Instagram DM?
Yes, if your tool supports it. Planoly Automations can send a PDF up to 25MB as one of the messages in an automation.
How do I collect emails from Instagram DMs?
The simplest way is to link to a sign-up page from your DM, using a card with a button. People enter their email on the page, which also lets your email tool handle the follow-up.
Should the lead magnet be free?
Usually, yes. The lead magnet earns trust and permission. The paid offer comes later, once they've used the freebie.
TL;DR
-

-
Match the format to the DM: PDF, photo, video, voice note, card or gallery.
-
Collect emails on a sign-up page linked from the DM, and measure sign-ups, not just sends.
