How to Create Instagram DM Automation for Free

Step 1: Set up a Manychat account (it’s free) and link it to your Instagram

To start building your Instagram DM automation, you’ll first need a Manychat account.

Manychat is one of the best Instagram DM Automation tools in the world. It’s the platform I recommend and personally use with all my clients.

Step 2: Add two tiggers to start the DM Conversation

Now it’s time to tell your automation when to start. In this example, we’ll build a simple DM automation that collects emails in exchange for a free investing guide.

Let’s say you’re offering a Free Investing Guide. The automation will trigger when someone sends you a message or comments on your content using a specific keyword like “GUIDE.”

To do this, head into Manychat, go to Automation, and click New Automation:

All automated flows start with a trigger. That’s what kicks everything off. In our case, we want the flow to start when someone:

• Comments on a post or reel
• Sends you a DM with a keyword

First, we’ll make a comment trigger. Click on Add trigger:

Then choose Instagram and User Comments on Post or Reel:

Next, you’ll choose which posts this automation should apply to. You can trigger it for:

1. One specific reel/post
2. All reels/posts
3. Only the next reel/post

I usually recommend using “All posts and reels”. That way, you only have to set it up once and it works for all posts.

Then, add the trigger keywords. In your post caption, you might say:

Comment “GUIDE” below to get my free investing guide!

The automation will trigger any time someone comments with “GUIDE” on your posts.

Inside Manychat, add GUIDE as a keyword, and include a few common typos just to be safe:

Now set up your Public Reply. This is the comment that appears under their original comment. It’s a great chance to get them excited and send them to their DMs.

So we will add three variations here and click on Create:

Manychat will randomly rotate between these replies so your comments don’t look copy-pasted or spammy.

That takes care of our comment trigger. Next, we’ll handle users who message you directly instead of commenting.

Let’s say you post a Story that says:

DM me “GUIDE” to get your Free Investing Guide!

Go back to Add Trigger, pick Instagram → User Sends a Message:

Choose message begins with, enter “GUIDE” and add a few close variations or misspellings just in case:

Now, whether someone comments or sends a DM with the GUIDE keyword, your automation will start.

Step 3: Build Your Instagram DM Automation Funnel

Now that your triggers are in place, it’s time to design the actual flow. These are automated messages in the DMs people will receive once they comment or DM you.

Because Instagram behaves different on mobile and desktop, we’ll split this automation in two parts:

1. First message after comment or DM
2. Follow-up automation to collect data and send your freebie

First message after comment

Inside Manychat, the first message should welcome the user and confirm that they want the free resource. Here’s a sample you can tweak:

Looks like you’re ready to make your first investment and earn some passive income!

Just click the button below or reply with “WEALTH” to get your free guide now 👇

Make sure this message is marked as Send as Private Reply. Otherwise, it won’t go through.

The next step is to add a quick reply. This is a button that people can tap on in their messages. When they do, it triggers the next part of your automation.

So, include a quick reply with something like this:

✅ YES, send it over!

Pro Tip: On desktop, quick replies don’t show up (Instagram limitation). That’s why we also instruct users to type the word “WEALTH”. 

Then, if people are on mobile, they can click on the quick reply. If they are on Desktop, they can type in the word.

Create the Follow-up automation to collect data

So, let’s make another automation, and then we’ll link the previous automation with this new one.

Now go back to Automation -> New Automation:

Choose Instagram, and User sends a message:

Write WEALTH, as well as some common typos, and pick Message begins with:

We want to make them excited. So, add a message that says something like “Awesome, just a few quick steps to get you access!”. Then, add 3 seconds of delay to make it seem more natural and human:

Next, you’ll build the actual sequence that collects their name and email. This can all be done within Instagram DMs.

Click on Data Collection:

Set it to collect the user’s first name. Choose Reply Type: First Name and change the expiration time to 23 hours (this gives users more time to answer):

Go down and and remove the “Skip” button text. This means that users can’t skip the step:

Let’s link this to another message:

Once they reply, send a new message using their name to keep it friendly and engaging:

Then ask for their email.

Click Data Collection again, this time set to Reply Type: Email. This tells Manychat to check if the email format is valid:

Scroll down and delete the “Skip” text again so they must fill it in.

If someone enters an invalid email, Manychat will automatically ask them again:

Once you’ve collected both name and email, it’s time to send your guide!

You’re all set, {{first_name}}!

Can’t wait for you to get started with investing!

Then add a button labeled something like “Access Free Guide” and link it to your resource. I will use Chatimize.com just for the sake of this example:

At this point, this is what the automation should look like:

Finally, link this second automation back to your original one using the Manychat block “Start Automation”. This connects the whole experience from trigger to delivery:

When everything looks good, hit “Set Live” in the top right corner. And you’re done!
