Short answer

In the post's automation editor, choose All comments in the Trigger box instead of Specific Comments, then write your DM and click Publish. Every new top-level comment on that post then gets the DM. All comments is available on Legend Pro and above. On the Free plan, use a trigger word instead.

Before you start

You need Legend Pro or a higher plan. On plans without it, All comments shows a crown and can’t be picked.
Think about volume. Every comment uses a DM, and on a busy post you can reach your plan’s hourly limit quickly.

Steps

On Home, click New Automation → Comment to DM → Existing posts. Pick your post and click Next.
Click Send Link & PDF. The editor opens.
- For a post that is already automated, open it from Quick Automation → Instagram → Posts and click the Send Link or PDF card instead.
In the Trigger box, click All comments. You’ll see “All comments will be automated.”
Set the public reply: add lines with Reply Comment, or switch Reply with comment! off.
Under Send a DM!, write your message.
Click Publish.

On the phone app

In the post editor (Send Link or Images → Edit Automation), open Trigger Words and choose All Comments. It is a paid option in the app too: the app sells Legend Pro under the name Starter. Then tap Publish.

What your followers see

Anyone who leaves a new comment on the post, even just an emoji, gets your DM a few seconds later.
If public replies are on, one of your reply lines appears under their comment.
If they don’t follow you and Instagram refuses the DM, a public comment asking them to follow is posted instead. See public comment replies.

Good to know

Comments are answered only from the moment you publish. Older comments are not messaged.
On a post that goes viral, some comments may wait or be skipped once you reach your plan’s hourly limit. Read What should I do when a post goes viral? before you use All comments on a big launch.
To keep one person out (a friend, a brand partner), add them to the whitelist. See How do I stop automations for a specific person?
If you use All comments on a post, your all-posts automation never answers that post: every comment already matches the post’s own automation.

What you can’t do

Skip comments that are only emoji or only a tag of a friend. All comments means every top-level comment.
Send the DM only once per person. Each comment counts.
Answer replies inside comment threads.

How to turn it off

Switch back to Specific Comments and add a word, or switch off the Send Link or PDF card. See turn off, edit or delete an automation.

If it doesn’t work

All comments is greyed out with a crown: your plan doesn’t include it. Use a trigger word, or upgrade.
Some comments got no DM on a busy day: check Why didn’t my automation send a DM? and the hourly limit in How many DMs can InstantDM send per hour?

Questions people also ask

Will someone get the DM again if they comment three times?

Yes. With All comments, each new comment gets its own DM and public reply. If people tend to comment many times, a trigger word may be a better choice.

Do my own public replies trigger more DMs?

No. Only top-level comments trigger. Replies inside a thread, including the public replies InstantDM posts, are ignored.

Can I do this for all my posts at once?

Yes. Create an all-posts automation and choose All comments in it. It shows as 'Any Comment / Reply' in the list.
