Some advertisers can now set up to five keywords that trigger an automatic direct message when a user posts them in a comment on a promoted Instagram post — a native comment-to-DM tool baked into the ad setup.

Meta is testing a new advertising option that automatically sends a direct message to anyone who comments a chosen keyword on a promoted Instagram post. Social Media Today reported the feature on August 25, 2026: some advertisers now see a "Reply to Keywords" option in their Instagram ad setup tools, described in the interface as a way to "save time by automatically sending a private message when people comment with a keyword."
Advertisers can choose up to five keywords, and each one triggers an auto-DM when a user posts it in a comment on the ad. In practice that looks like the familiar "comment WINNING for more info" prompt: the ad invites a keyword, the commenter types it, and Instagram's tools fire off the private message automatically instead of the advertiser replying by hand. It turns a public comment into a one-to-one DM thread — the start of a lead-nurture or sales conversation — without manual work on the first touch.
For now the option is appearing only in Instagram's ad setup tools, not for Facebook ads, and it reads as a limited test — "some Meta advertisers can now access" it rather than a full rollout. The capability itself is not entirely new for Meta: comment-to-DM automation has long been available through third-party tools and, more recently, through Meta's own inbox automation and Business Agent features. What is notable here is that it is being built directly into the paid Instagram ad flow, tied to promoted posts.
Meta has spent the past few years pushing more business activity into messaging, positioning DMs as where conversions increasingly happen. Treat the specifics — keyword limit, availability, and exact behavior — as the reported state of a test as of late August 2026, and confirm current availability in your own Instagram ad tools before planning around it.
The useful read on this test is that an auto-DM is downstream of a post someone actually wanted to comment on — and that post still has to be made, stay on-brand, and keep coming. Reply to Keywords handles the first reply; it does not write the ad, film the hook, design the carousel, or run any channel but paid Instagram. The bottleneck it exposes is supply: keyword auto-DMs only pay off when you are consistently shipping scroll-stopping, comment-inviting creative. That production layer is exactly what [Kompozy](/) is. Point it at one source and it generates a week of Instagram-ready assets — [Persona Shorts](/glossary/persona-shorts) with a strong opening hook and a built-in "comment X" call to action, brand-exact [carousels and quote graphics](/glossary/hyperframes), and platform-native captions written in your voice — the kind of posts that earn the comments the auto-DM then catches.
Two things make that content keyword-campaign-ready rather than just postable. Voice: a [Persona Brief](/glossary/persona-brief) keeps the hook, the CTA, and the caption consistent across every asset, so your "comment WINNING" prompt reads the same whether it lands on a Reel or a carousel. Reach: while Reply to Keywords is Instagram-ad-only, [Autopilot](/glossary/autopilot) captions, resizes, and schedules the same campaign across the eight social platforms plus blog and email, each asset clearing a per-post review gate first — so the comment-to-DM play on Instagram sits on top of a full, on-brand content operation everywhere else. Meta will automate the reply; Kompozy is how you keep producing the posts worth replying to.
Reply to Keywords is a Meta advertising option, reported in testing in August 2026, that automatically sends a direct message to anyone who comments a chosen keyword on a promoted Instagram post. Advertisers can set up to five keywords, and each triggers an auto-DM. It is described in the ad tools as a way to save time by messaging commenters automatically, and it currently appears in Instagram ad setup only, not Facebook.
According to the reporting, advertisers can choose up to five keywords per ad. Each keyword triggers an automatic private message when a user posts it in a comment on the promoted post — the classic "comment WINNING for more info" pattern, handled automatically instead of by manual reply.
No. Reply to Keywords only automates the first DM sent to someone who comments a keyword. It does not generate the ad creative, write the caption, design the post, run the follow-up conversation, or publish to any other platform. You still need to produce the comment-earning content and manage the conversation beyond the initial auto-message.
As reported in August 2026, the Reply to Keywords option is appearing only in Instagram ad setup tools, not for Facebook ads, and it reads as a limited test rather than a full rollout. Comment-to-DM automation is separately available through third-party tools and Meta's own inbox automation and Business Agent features. Confirm current availability in your own ad tools.
