Meta is testing a feature called Reply to Keywords that sends an automatic Instagram DM when someone comments a chosen keyword on your ad. You pick up to five keywords, write one message, and Meta sends it privately. In other words, Meta is building comment-to-DM into Ads Manager.
The short decision: if your comments come from paid ads and a single link is all you need to send, the native option may be enough once it reaches you. If your comments come from organic Reels, or the DM has to do more than hand out a link, nothing about this test changes your setup.
What the test does
These points come from Social Media Today's report of 25 August 2026 and from Jon Loomer, the Meta ads specialist who first spotted the option.
- Where it lives: Instagram ad setup. It was not seen in Facebook ad tools.
- Triggers: up to five keywords or phrases in a comment on the ad.
- The message: one private reply that can carry text, a link, a phone number, or an email address.
- Meta's own description: "save time by automatically sending a private message when people comment with a keyword."
- Status: a limited test. Meta has not announced it or said when, or whether, everyone gets it.
Treat everything beyond those points as unknown. There is no public documentation yet, so questions like case sensitivity, reporting, and whether it works on every ad format have no confirmed answers.
What it cannot change: one comment, one message
Native or third-party, every comment-to-DM automation sends through the same Instagram mechanism, the private reply. Meta's developer documentation is explicit: only one message can be sent to the commenter, it must go out within seven days of the comment, and further messages are allowed only if the person replies, within 24 hours of their reply.
So Reply to Keywords is not a way around the rules. It sends the same single message a tool would. If you have been hoping Meta's own feature would allow follow-ups or reminders, it cannot. Our guide to Instagram's DM windows explains how the seven-day and 24-hour clocks interact.
The same rule creates a practical trap. Inference from Meta's one-message rule: if you boost a post that already runs a comment-to-DM campaign and also switch on Reply to Keywords, both automations will try to reply to the same comment. Only the first can succeed. The follower gets whichever message won the race, and the other system logs a failure. Run one automation per post.
Meta already had a native option for organic posts
This is not Meta's first comment-to-DM feature. Meta Business Suite's Inbox automations already include a Comment to message template for organic posts. Third-party setup guides describe it as desktop only and triggered by hashtags rather than free-text keywords. Meta also sells Meta Business Agent, an AI assistant for answering DMs, which is a different job again.
What is new is the placement. Reply to Keywords attaches the automation to the ad itself, so an advertiser setting up a campaign can add the DM in the same flow instead of configuring the Inbox separately.
Which option fits which job
| Job | Reply to Keywords (test) | Business Suite Comment to message | Dedicated comment-to-DM tool |
|---|---|---|---|
| Comments on paid ads | Yes | Organic posts only | Depends on the tool |
| Comments on organic Reels | Not reported | Yes | Yes |
| Follow before the reward | Not reported | No | Some tools |
| Referral links and bonus rewards | Not reported | No | A few tools |
| Tracking who entered, picking winners | Not reported | No | Some tools |
| Extra cost | Included with ad spend | Free | Subscription or per campaign |
"Not reported" means none of the coverage mentions it. It is not a confirmed "no", because Meta has published nothing yet. The dedicated-tool column varies a lot by vendor, which is why our comment-to-DM automation guide compares the features that matter.
Who should use which
Advertisers running lead-generation ads with one destination, such as a booking page, a catalogue, or a WhatsApp number, are the audience Meta built this for. When the option reaches your account, it is the simplest way to answer "comment INFO" on an ad without another tool.
Creators running giveaways, drops, or launches on organic Reels are outside its reach. Most of that comment volume never touches an ad, and those campaigns usually need more than a link: a follow before the reward, a referral link, or a record of who entered.
Anyone doing both should split by post. Use the native option on ads that exist only as ads, and keep your tool on organic content. Before boosting a post that already runs a campaign, decide which system owns it.
What to watch next
Three things will decide how much this matters: whether it reaches all advertisers, whether it comes to Facebook ads, and whether Meta reports how many DMs it sent and how many people clicked. Until Meta documents it, plan around the fixed part, the one-message rule, rather than the parts that are still a test.

Checked on 2026-09-25. The feature is an unannounced test, so details may change without notice.

UnlockDM runs comment-to-DM campaigns on organic posts and Reels, with a follow gate and referral rewards when a campaign needs them. If a post is also boosted, keep native auto-replies off so the two never compete for the same comment.
