Comment-to-DM script & keyword CTA generator

Use a single, easy-to-spell word (avoid punctuation or spaces so mobile autocorrect doesn't break matches).

Describe the specific lead magnet, product link, or discount.

Why rotate replies? Instagram's anti-spam classifier flags accounts that post the exact same public comment reply (“Sent!”) 50+ times in an hour. Always load at least 4 randomized public reply variations in RapidDM.

Tool guide and methodology

How this calculator & framework works in 2026

3 min read•

A Comment-to-DM funnel only works if viewers type your trigger word in the comments and actually find the message that lands in their inbox.

Two preventable mistakes hurt conversion rates on automated Reels:

  1. Choosing a trigger keyword that mobile autocorrect changes mid-type, such as brand acronyms or multi-word phrases.
  2. Posting the exact same public comment reply ("Sent!") dozens of times in an hour, which trips Instagram's repetitive-comment filter.

Use the generator above to build a four-part script pack for your next Reel or carousel post, then check the table below when picking your trigger keyword.

How to choose a trigger keyword that converts

Why you should load at least 4 public comment reply variations

When RapidDM sends a Private Reply DM, it can also post a public reply right beneath the viewer's comment (for example, "Just sent it to your DMs!"). Public replies do two useful jobs:

  1. They remind the commenter to check their Instagram inbox right away, which matters when they do not follow you yet and the message lands inside Message Requests.
  2. They double the visible comment count on your Reel, signaling active discussion in the thread.

Meta's anti-spam system watches for accounts that post identical comment replies in rapid succession. Loading four or five natural reply variations into your RapidDM campaign — combined with a randomized 2 to 5 second reply delay — keeps your public replies looking human even on busy posts.

Common questions

Frequently asked questions

What is the best keyword to use for Instagram Comment-to-DM automation?

Single, concrete nouns between 4 and 7 letters perform best—such as GUIDE, LINK, SHOP, AUDIT, or SETUP. Avoid two-word phrases, emojis, or words commonly altered by iOS autocorrect.

Why should I use multiple public comment reply variations?

If your account replies 'Sent! Check your DMs!' verbatim to 80 comments in a row, Instagram's automated spam detection can temporarily block public comment replies. Rotating 4 to 6 natural variations prevents spam flags.

Should I use Exact Match or Contains Match for my keyword?

Use 'Contains' or 'Any word' matching for your primary keyword so commenters who write 'GUIDE please!' or 'Can I get the GUIDE?' still receive the automated DM.

Why do some non-followers miss my automated DM?

When a user does not follow you, Instagram routes your first automated Private Reply into their Message Requests tab. Mentioning 'Make sure you follow me so my DM doesn't land in Hidden Requests' in your caption boosts open rates.
