IG Comment-to-DM Trigger Fires (“You messaged {user_name}…”) But No DM Is Actually Sent

Hi everyone,

I’m experiencing a recurring issue with Instagram Comment-to-DM automation in ManyChat.

When someone comments under my post, I see the system message in Instagram that says:

“You messaged {user_name} about a comment they made on your post. See Post.”

However:

  • No actual DM is sent.

  • The user does not receive any message.

  • The flow does not appear to trigger.

  • There is no visible error inside ManyChat.

  • This happens frequently, not randomly once in a while.

Important details:

  • IG account is Professional and properly connected.

  • Permissions have been refreshed multiple times.

  • Page is connected via Meta Business Manager.

  • Automation is published and turned ON.

  • The post is selected correctly inside the trigger.

Hi ​@emircodesall , is this an organic post or a paid post…?  because if its paid the best way to do it is through IG triggers/Partner App option. You can se a guide here on how to set it up: https://help.manychat.com/hc/en-us/articles/14281321942428-Instagram-Ads-Trigger

If its an organic post,  here are a few things I’d recommend double-checking:

  1. Instagram permissions
    You already mentioned you refreshed permissions, which is usually a quick fix, but since it didn’t work in your case, we can rule that out for now.
  2. Follow the official IG automation troubleshooting guide
    This step-by-step guide covers several edge cases that can cause comment automations to stop firing and is very helpful for diagnosing issues like this:
    https://help.manychat.com/hc/en-us/articles/14281308423452-Instagram-automation-troubleshooting
  3. Check for platform-wide issues
    Sometimes this is related to a temporary issue on Instagram or ManyChat’s side. You can check the current system status here:
    https://status.manychat.com/
  4. One-time trigger behavior
    Just as a reminder, Instagram comment automations only trigger once per user per post. If the same user commented again, the automation would not fire a second time.

Hopefully one of these points helps you pinpoint the issue. If nothing works, you can contact Manychat support:  How to get support from Manychat – Manychat Help

Cheers,

      Hi, the issue has not been resolved yet. I have been having this issue since February 14th, and for the past few days it has gotten to a point where my page is critically affected operationally. My DM automations are a core part of my lead capture and customer communication process, and they are currently unreliable. I have tried the steps you have given, none gave any solutions to this problem

      If the “You messaged…” notice appears but no DM is delivered, the trigger is firing but Instagram is blocking the actual message.

      This is usually a Meta side restriction or rate limit, especially if you send high DM volume. ManyChat will not always show an error.

      Check Account Quality and messaging limits in Meta Business Suite. Then test with a brand new post and a very simple text only flow. If it still fails, you will need to contact ManyChat support with timestamps so they can review delivery logs.

        How can i contact the ManyChat support? I have sent a ticket through the automated helper bot on Thursday, but had no feedback yet. How long does it usually take?

        Instagram Comment-to-DM fires but no DM is sent because Meta may block messages due to restrictions or rate limits. Check account quality and messaging limits in Meta Business Suite. Test with a new post and simple flow. If it still fails, contact ManyChat support here: https://help.manychat.com/hc/en-us/p/get_support_page
