Let’s build the most popular automation: sending a direct message to anyone who comments a specific keyword on your Instagram Reel or Post.

Step 1: Choose Your Trigger

  1. Navigate to Automations in your dashboard and click Create Custom Automation.
  2. Under “What should trigger this automation?”, select Comment on Post (or Reel Comment).

Step 2: Select Your Content

DMRocket will automatically fetch your recent Instagram media.
  • Click on the specific post(s) you want this automation to run on.
  • Alternatively: Toggle Apply to all future content if you want this keyword to work on every post you make from now on.
  • Click Continue.

Step 3: Define Your Keyword

You don’t want to DM every single person who comments—only those asking for your link.
  1. Toggle the match type to Exact Match or Match Any.
  2. Type a keyword (e.g., “LINK” or “INFO”) and press Enter.
  3. Click Continue.

Step 4: Craft Your Message

This is the message the user will receive in their DMs.
  1. Type your opening message (e.g., “Hey! Thanks for commenting. Here is the link you asked for!”).
  2. Add a Flow Trigger Button text below it (e.g., “Get the Guide”).
  3. Click Add Next Step and select Text Message or Card Message to add your actual URL.
  4. Set up your Public Comment Replies at the bottom of the page. DMRocket will randomly select one to reply to the user’s comment publicly (e.g., “Sent to your DM! 🚀”).

Step 5: Launch

Click Review & Launch. Give your automation a memorable name, double-check your keyword and trigger settings, and hit Launch Automation. Your auto-reply is now live! Go to your Instagram account from a secondary profile and test commenting your keyword to see the magic in action.
