ReachleeTurn every Facebook comment
into a Messenger conversation.
Someone comments your keyword on a Page post. Reachlee replies under the comment and sends them a private Messenger message with your link, offer or next question — in seconds, on every post you choose.
Can you automatically message someone who comments on a Facebook post?
Yes. When someone comments a keyword on your Facebook Page post, Reachlee replies under the comment and sends that person one private message in Messenger with your link, offer or next question. Meta allows one private reply per comment, within 7 days of the comment. It works on one post, up to 10 chosen posts or every post, including boosted ones, and Facebook Pages are included from the Pro plan.

What is Facebook comment-to-Messenger?
It is the Facebook Page version of Instagram comment-to-DM. A keyword in a comment triggers a private message to that person's Messenger, sent through Meta's private-replies feature, so a public comment becomes a one-to-one conversation. There you can share a link, answer the question or capture a lead, while the comment section fills with genuine engagement instead of 'check your inbox' replies typed by hand.
- Trigger: someone comments a keyword such as LINK, PRICE or GUIDE on a Page post you picked — or any comment, if you prefer.
- Action: an optional public reply under the comment, and your private message in Messenger.
- Result: every commenter gets a fast, personal-feeling answer, and you see who clicked.
What happens after someone comments.
The comment arrives
Meta delivers the comment to Reachlee within seconds. Reachlee checks it for your keywords — case-insensitive, and only where the keyword starts a word, so 'link' never fires on 'blinking' — or answers every comment if you chose that.
A public reply, if you want one
Reachlee replies under the comment with one of your rotating lines, such as 'Sent you the details!'. Other readers see the Page answering, which tends to bring in more comments.
The private reply in Messenger
The commenter receives your message in Messenger: text, buttons, a tracked link or a question. This is the one private reply Meta allows for that comment, so it is worth making it count.
The conversation opens
When they tap a button or reply, Meta's 24-hour window opens. Reachlee can then send the link, a product carousel, an email or phone question, and one follow-up if they go quiet. For more steps, such as a quiz, a wait or an A/B split, build the automation as a flow on the visual canvas, which takes Page comment triggers too.
What you can put in the private reply.
A link behind a button
Your link sits behind a button and every click is tracked per automation. You can also send it as plain text if you prefer.
A question first
'Want the guide? Tap below.' The tap opens the 24-hour window, so the link, a lead question and a follow-up can all follow.
A product carousel
Up to 10 cards with three buttons each — ideal when the post shows several products and people ask 'how much?'.
An email or phone ask
Collect a contact detail before you deliver the reward. Reachlee checks the format and saves the lead; on Business it goes straight to Google Sheets.
One follow-up
A single reminder inside the 24-hour window if they don't reply or tap, cancelled the moment they do.
Campaigns that work well on Pages.
Giveaways
Entries arrive as comments and you confirm each one by hand.
Comment ENTER: a public 'You're in!' plus a private message with the rules and the closing date.
Lead magnets
A free checklist post gets hundreds of comments and nobody can keep up.
Comment GUIDE: the checklist arrives in Messenger after a quick email step, so the list grows with every comment.
Events and webinars
Sign-up links pasted into replies get buried and go stale.
Comment SEAT: the registration link and date land privately, with one reminder if the person doesn't tap.
Menus and price lists
'Price?' is asked forty times under the same post.
Comment PRICE: the price list and a booking or order button arrive in Messenger straight away.
Product drops
Launch-day comments outpace the team answering them.
Comment DROP: a carousel of the new products, each card tracked, delivered while the post is still trending.
Facebook comment-to-Messenger vs Instagram comment-to-DM, in Reachlee.
| Facebook Page | ||
|---|---|---|
| Where the message lands | Instagram DMs | Messenger |
| Private replies Meta allows | One per comment, within 7 days | One per comment, within 7 days |
| Public reply under the comment | Yes | Yes |
| Ask for a follow before the link | Yes (Growth Gate, Pro) | No — Meta has no follower check for Pages |
| Comments from before you started | Retrigger, last 7 days | Retrigger, last 7 days |
| Plans | Free and up | Pro and up |
It is free and fine for one fixed text reply. It can't reply publicly under the comment, send a link button or a carousel, ask for an email, follow up, or act on comments from before you switched it on, and it waits up to 15 minutes unless you answer first. If your Page runs campaigns rather than one standing reply, those gaps are the whole job. The full comparison covers each limit.
The rules every tool works within.
One private reply per comment, sent within 7 days of the comment; after that you can continue only if the person responds, which opens a 24-hour window. Meta caps each Page at 750 private replies an hour, and Reachlee paces a viral post under it automatically. Brand-new Pages sometimes see their first messages land in Message Requests or Spam; that fades as the Page has real conversations.

Pro is $9/mo (₹499 in India): unlimited DMs, contacts and leads, automations on every post, Retrigger and follow-ups, and 3 connected accounts shared between Instagram and Facebook Pages.

Get startedFacebook comment-to-Messenger — questions.
Does it reply to every comment or only to keywords?
Either. Set one or several keywords per automation, or choose any comment. Keyword matching is case-insensitive and only fires where the keyword starts a word. On Growth, Reachlee AI can also answer the comments your keywords don't catch, from your Page's knowledge, with any link sent privately in Messenger.
Can one automation cover several posts?
Yes: one post, a hand-picked set of up to 10 posts, or every post on the Page, including ones you publish later.
Does it work when I boost the post?
Yes. Comments on the boosted version of a Page post reach Reachlee and fire the automation, as long as the automation's scope includes that post or covers every post.
Can I reach people who commented before I set it up?
Yes, for comments from the last 7 days. Retrigger runs the automation over those comments, skips anyone already messaged and paces the sends, at most 200 new people per Page a day. Older comments are outside Meta's private-reply window for every tool.
Can I see who clicked the link?
Yes. Links are tracked per automation, so you can see runs and clicks for each campaign in Reachlee, and because Facebook Pages run on Pro and above, you also see who tapped, with repeat taps and a jump to their conversation.
Can I message the commenters again later?
Inside Messenger's rules, yes. Everyone who taps or replies becomes a contact you can file into folders, and a campaign can send them a message or a short sequence later. Meta allows free-form messages within 24 hours of the person's last message, so people outside that window get the campaign when they next message your Page. Nobody can be messaged first.
Is comment-to-Messenger on the Free plan?
No. Facebook Pages start on Pro ($9/mo). The Free plan covers one Instagram account, where comment-to-DM works the same way.
