Instagram DM Automation

Reel, comment, DM, link, follow-up

Almost everything people mean by Instagram DM automation is one loop. Here it is with nothing left implicit.

• You post a Reel that ends on a line like: comment GUIDE and I will send it over.
• Someone comments GUIDE. Instagram fires a webhook and ReelDrop matches the keyword against it.
• ReelDrop posts a short public reply on that comment, so the next few hundred viewers can see the keyword does something.
• It opens a DM with the commenter. If the follow gate is on, the link waits behind a follow check.
• The DM delivers what you promised, as a tappable button: a link, a PDF, a discount code, a checkout page.
• A follow-up you wrote earlier lands 30 minutes to 24 hours later, and cancels itself if they already replied.

The automation is attached to the post while you schedule it

Most people run this loop on two subscriptions. A scheduler publishes the Reel on Tuesday morning, then you open ManyChat or something like it, hunt for the post that just went live, and wire the keyword to it by hand. Two bills, two logins, and a gap where the Reel is public but the automation is not running yet.

In ReelDrop the automation picker sits in the composer. You choose the automation while you are choosing the time slot, and it goes live attached to that post the moment the post publishes. ManyChat cannot do this half at all, because ManyChat has no post publishing. A handful of schedulers have added comment-to-DM in the last year, so ReelDrop is one of the few tools that does both rather than the only one. It is still one bill instead of two.

You can also build the automation first and leave it waiting. It sits dormant until a post claims it, which is the sane order when you are batching a launch week on a Sunday night.

Set the trigger

Three things can start an automation: a comment on a post or Reel, an incoming DM, or a story reply. Pick one, then decide how wide it casts.

Keywords are matched three ways. Contains catches guide please!! and send me the guide. Exact fires only when the comment is the word by itself. Any skips keywords entirely and responds to every comment, which is the right setting for a giveaway and the wrong setting for a post that attracts arguments. You can point the automation at one specific post from a grid of your recent media, at a post you have not published yet, or at everything you post. A per-post reply limit caps how many public replies go out if a Reel gets away from you.

Write the public reply and the DM

The public reply is the part other viewers see. Write a few variants, or start from ReelDrop presets, and each commenter gets a different one, so the comment section does not turn into a wall of identical replies. There is a pre-generated bank if you would rather not write ten of them yourself.

The DM is the part that matters. By default it opens with a short message and a button, and the link card arrives once they tap. That tap is doing real work: the person confirms they want the thing before a link from a stranger lands in their inbox. Turn the opening step off if you would rather send the link straight away.

You can attach up to three link buttons, each with a label of 20 characters or fewer, and every URL is checked as https before it saves. A live phone preview shows the whole conversation the way the commenter will read it, which is how you catch an awkward line before a thousand people get it.

The follow gate, and what verification actually means

A viral Reel hands your lead magnet to a lot of people who will never come back. The follow gate is the fix: before the link goes out, ReelDrop asks the commenter to follow you, then delivers it.

The word verification is doing something specific here. ReelDrop asks the Instagram Graph API whether that account actually follows your business account, so the gate is a check rather than an honor system. When the API cannot answer for a given account, ReelDrop falls back to trust mode and sends the link anyway instead of stranding someone who did follow you. Plenty of tools call this a follow gate and never check anything.

Follow-ups that cancel themselves

Set one follow-up on a delay you pick, anywhere from 30 minutes to 24 hours. It goes to people who got the link and then went quiet. If they reply in the meantime the follow-up is cancelled before it sends, which is the rule that keeps this a nudge instead of the tool talking over a conversation you are already having.

What each automation reports

Every automation carries its own counts: events received, public replies posted, DMs sent, button taps and tap rate where Instagram lets us observe it, replies and reply rate. That is enough to tell a dead keyword from a dead Reel.

When an offer runs its course, pause the automation instead of deleting it. The setup and the numbers are still there the next time you run it. Cloning an automation gives you a copy that arrives paused, so a half-edited duplicate cannot start answering people. And if you switched an automation on late, retrigger replays comments that already happened, up to 50 per post across five posts.

The lead magnet Reel

A nutrition coach posts a Reel that ends with comment MEALS and I will send you the plan. The automation replies in public, checks the follow, and delivers the link by DM. She wakes up to new subscribers instead of a comment section full of requests she has to answer by hand.

Launch day without the inbox shift

A course creator opens enrollment and pins a post with the keyword JOIN. Every commenter gets the checkout link within seconds, including the ones commenting at 2am, which is somehow always a lot of them.

A pottery teacher's launch, day by day

A ceramics teacher opens her wheel-throwing course on Monday with a Reel: comment WHEEL for the syllabus. By Monday night there are 60 comments, each with a public reply and the syllabus delivered by DM. Tuesday she notices half the commenters are not followers and switches on the follow gate. Wednesday she adds a follow-up on a 24-hour delay for people who got the link and went quiet. By Friday the automation has handled a few hundred conversations, and the only DMs she typed herself were actual questions about the course.

What DM automation costs

ReelDrop's free plan includes 5 active DM automations plus a full Instagram Reels scheduler, and it never asks for a credit card. Five automations covers most creators: one evergreen lead magnet, one per active launch, and a spare.

The comparison worth making is what the same workflow costs as two products. A scheduler runs $15 to $25 a month, and a dedicated DM tool starts around $15 and climbs with your contact count. ManyChat cut its free plan to 25 active contacts in March 2026, which is why so many creators went looking for something else this year.
