Automatically send a Messenger DM to anyone who comments on your Facebook Page’s Post or Reel — perfect for sending a link, a freebie, or a “here’s the details” reply the moment someone shows interest.

What you’ll build
A “comment-to-DM” automation watches a Post or Reel on your connected Facebook Page. When someone leaves a comment — optionally one that contains a keyword you choose — your Page sends them a private Messenger DM with your message and an optional button (for example, a link to your product, course, or booking page).
How a comment-to-DM automation appears in your AutoDM list once it’s live.
Before you start
Connect your Facebook Page. You’ll need a Facebook Page connected to AutoDM, and you must be an admin of that Page. (See Connect your Facebook Page.)
Have your Post or Reel ready. The automation triggers on comments on a specific Post/Reel of your Page, so it helps to know which one you’ll attach it to.
Know your message. Have the DM text — and the link for the button — handy.
Step-by-step
Open AutoDM and start a new automation
Go to AutoDM in your SuperProfile dashboard and click Create Automation (top-right). You’ll be asked which platform this automation is for — choose Messenger.
Choose the “comments on your Post/Reel” trigger
Pick the trigger When someone comments on your Post/Reel. This is the comment-to-DM flow.
Select which Post or Reel to watch
Choose the specific Post or Reel you want this automation to monitor. The automation only fires for comments on the Post/Reel you attach here, so make sure it’s the right one.
Set your keywords
Decide what kind of comment should trigger the DM:
Any comment — every comment on that Post/Reel triggers the DM.
Specific keyword — only comments that contain a word you choose (for example, collab or link) will trigger it.
A few things worth knowing about keyword matching:
Keywords are not case-sensitive — “Link” and “link” are treated the same.
Matching is on whole words — the keyword ai matches a comment that says “ai” but not “pain”.
You can also add excluded keywords so certain comments never trigger the automation.
5. Write your primary DM and add a button
This is the message the commenter receives. Write a friendly note and, if you like, add a button that links to your product, page, or booking link.
You can also choose the DM type:
Text + Button — a message with an optional link button (most common).
Image / Video — lead with a visual.
Card — an image, title, and subtitle with a button.
Voice message — a personal audio note.
6. (Optional) Add follow-up messages
Want to nudge people who don’t reply? Add one or more follow-up messages that send after a time delay (for example, a second message 2 minutes later). On Messenger, follow-ups are sent on a timer — “after a time delay.”
ℹ️ Heads-up: follow-ups add a “tap to receive” step
When a comment-to-DM automation has follow-ups, Messenger first sends a short conversation-starter note — “tap the button below to receive your message.” When the person taps it, your primary DM (and the follow-ups) are sent.
Why? Meta only lets your Page send one message to someone who commented. The tap re-opens the conversation so the rest can be delivered. This is normal and required — and it only applies when you’ve added follow-ups.
7. (Optional) Set a time delay
If you’d like a pause between the comment and the first message, set a time delay (for example, “wait 1 minute after the trigger”). Your first message is sent after that wait.
8. Review and launch
You’ll see a summary of the whole flow — the trigger, your keywords, any delay, the primary DM, and any follow-ups. Read it through, then click Confirm & launch. You’ll get a “Messenger Automation Launched!” confirmation, and the automation appears in your AutoDM list, ready to go.
After you launch: where your DMs land
There’s one important thing to know about comment-to-DM on Messenger: when your Page messages someone for the first time, Meta places that DM in the person’s Message Requests (and sometimes the Spam sub-tab) until they open it.
⚠️ This is normal — not a bug
Every comment-to-DM tool runs into this. Once the person opens, taps, or replies to your first message, future messages land in their main inbox. A simple line in your Post like “Check your Message Requests (and Spam) for my DM!” helps a lot.
See Why your DM landed in Message Requests or Spam for the full explanation.
Tips for better results
Tell commenters where to look (“check your Message Requests / Spam”) right in the Post caption.
Keep the first DM short and welcoming — you can put the detail behind the button.
Use a clear keyword (like link or guide) and mention it in your Post: “comment guide and I’ll DM it to you.”
Frequently askedCan I use the same automation for all my posts?
A comment-to-DM automation is attached to the Post/Reel you select during setup. To cover another Post, set up a separate automation for it.
Why didn’t my comment trigger a DM when I tested it?
A person commenting as the Page itself won’t trigger the automation, and there’s a short built-in delay on comment replies. Also check that the automation is Enabled, that your comment contains the keyword, and look in Message Requests / Spam. See Comments on my post aren’t triggering a DM.
Can I personalise the DM with the person’s name?
Personalisation variables (like Name) aren’t available on Messenger yet — they’re coming. For now, write a warm, general message.
