Can an automation reply only once per person?

Before you start

Here is what each automation does when the same person triggers it again:

Automation	Same person again
Comment to DM (any type)	Gets the DM and public reply again, every time
Story to DM	Gets the DM again, every time
DM keyword	Gets the reply again, every time
DM Any Message + First time only	Never again
DM Any Message + Once a day	Again after 24 hours

Steps

For DMs, use Any Message with First time only:

1. On Home, click New Automation and choose DM Automation.
2. Click Instagram DMs, then Next, then Lead Gen.
3. Under ENTRY POINT, choose Any Message.
4. Under ⏱️ Select Interval, choose First time only.
5. Add your reply with Add Step → Text Message.
6. Click Save, then Publish & Activate.

Full guide: auto-reply to everyone who messages me.

In Flow Automation: skip people with a tag

This needs Trendsetter and above. It works best for keyword DMs.

• Right after the trigger, add a Condition step with the rule Tag → doesn’t have tag → for example got-guide.
• Connect True to your messages. Leave False empty, or connect a short “You already have it” message.
• After your messages, add a Tag Contact step that applies got-guide.
• Click Set Live.

For comment flows, the welcome message and public reply still go out each time. The tag check only stops the steps after the person taps the welcome button. See tag contacts and different messages by answer or tag.

On the phone app

In the DM tab, tap Create New, choose Automate All Messages and set ⏱️ Select Interval to First time only. Flows with tag checks can only be built on the web.

What your followers see

With First time only, a person gets your reply on their first message and never again. With a comment automation, they get the DM each time they comment your keyword.

Good to know

• Rarely, the same person can get a DM twice even with First time only, for example when Instagram sends two messages a second apart.
• In flows, Ask only if unknown on a question skips it when the person already answered it in any flow on your account. That avoids asking twice, but the flow still runs.

What you can’t do

• Limit comment or story-reply automations to once per person.
• Skip the public comment reply for repeat commenters.
• Use First time only on keyword DMs.

How to turn it off

To let people get the reply again, switch ⏱️ Select Interval to Once a day, or remove the tag condition from your flow and click Set Live. See turn off or edit an automation.

If it doesn’t work

• Someone got the DM twice: see why did someone get my DM twice?.
• Nobody gets the Any Message reply any more: with First time only, everyone who already got it once is skipped.
