Instagram Product Post DM: Send Purchase Links Automatically
Learn how to automate your Instagram product posts so every interested commenter gets the purchase link in their DM before they scroll away.
When someone comments on your product post, they’re expressing buying intent. That’s not a casual interaction — it’s a signal that they want to know more or are ready to buy. The question is whether your response arrives fast enough to capture that intent.
Instagram product post DM automation sends the purchase link, price, or product details in the commenter’s DM within seconds, automatically — before the person moves on to the next thing in their feed.
The problem with manual product responses
Post a product on Instagram and the typical response chain looks like this: someone comments “how much?” — you see it 3 hours later — you respond in the comments — they miss the reply — interest gone.
Or: you respond fast, they ask a follow-up in comments, it becomes a public thread, the conversation fragments, and the purchase never happens.
DMs solve both problems. They’re private, conversational, and keep the buying intent alive in a direct channel.
The issue with manual DMs for products is scalability. If 50 people comment a product post, you can’t send 50 personalized DMs within the window of peak intent. Automation handles that volume instantly.
How to set up comment-to-DM for a product post
Step 1: Pick a keyword that fits the product. The keyword should match the post’s offer. “PRICE” works for price inquiries. “LINK” works for purchase links. “SHOP” or the product name itself works for collections. Keep it to one word.
Step 2: Write a caption with a clear keyword CTA. Example: “New drop available now. Comment SHOP and I’ll send you the full product details and checkout link directly in your DMs.”
Step 3: Design the product DM. The DM should include:
- Product name and a brief, punchy value proposition (1-2 sentences).
- Price or price range.
- Key details (sizes, flavors, options if relevant).
- Direct checkout link.
- A quick-reply option: “Already ordered” / “Have a question.”
Step 4: Add a follow-up for non-purchasers (optional). If a lead received the DM but didn’t click the link within 24 hours, an automated follow-up: “Hey [name], still interested in [product]? Happy to answer any questions before you decide.”

Product post formats that get the most comments
Not all product posts generate the same comment volume. The formats that drive the most keyword comments:
Product reveal reels. Showing the product being used, packaged, or unboxed. End with a screen card or voiceover: “Comment LINK to get yours.”
Before/after posts. Especially effective for beauty, fitness, food, or any product with a visible transformation. The after image drives desire; the CTA captures it.
Limited-edition or drop announcements. “This colorway is dropping [date]. Comment ALERT to be notified in your DMs with the purchase link the moment it goes live.” Builds anticipation and captures the highest-intent audience before the drop.
Comparison posts. “This vs. that” carousels that show your product against a competitor or alternative. Position yours clearly and close with “Comment SHOP to get ours.”
Customer review reshares. Screenshot a real customer review or testimonial with your product. Add: “Comment STORY if you want to know more.” The DM delivers context on the product and the purchase link.

Handling product questions inside the DM flow
A well-designed DM flow doesn’t just send the purchase link — it handles the most common questions before they become friction points.
Quick-reply buttons in the DM can offer options like:
- “What sizes are available?”
- “Do you ship internationally?”
- “Can I see more photos?”
- “What’s the return policy?”
Each option triggers a pre-written response. The lead gets their question answered instantly, without waiting for a human response, and the path to purchase stays open.
This is particularly effective for products with complex sizing, technical specifications, or common objections that show up repeatedly in comments.

FAQ
Can I send different product DMs for different posts? Yes. Each post gets its own keyword and its own DM flow. A post about product A uses keyword “SHOPBLUE” and sends the blue product DM. A post about product B uses “SHOPRED” and sends the red product DM. You can manage dozens of active product automations at once.
Does the automation work for story posts that mention the product? Breeze handles both comment-to-DM (from feed posts and reels) and story reply-to-DM. For stories, the trigger is a reply to the story rather than a comment keyword. This covers the full range of product discovery on Instagram.
Can I include a product image in the automated DM? Direct API-based DMs support text and links. If you want the product image visible, a clean option is linking to a product page that leads directly to a visual product view, or creating a simple landing page with the product image and checkout button.
What happens if a product sells out while the automation is running? You can pause or edit the automation at any moment from the Breeze dashboard. When a product sells out, pause the automation so new commenters don’t receive a link to an out-of-stock page. You can update the DM to a waitlist link instead.
Can I track which DMs actually converted into purchases? Breeze shows who received the DM and who replied. For tracking actual purchases, use a unique UTM link or a product page specifically for Instagram DM traffic. This lets you see in your analytics platform how many sessions from the DM link resulted in a completed order.
