One Post, One Keyword, One Automation: The Cleanest Way to Start DM Flows

This guide walks through that exact build inside BooSend, step by step. The same setup pairs naturally with comment automation, an AI sales agent, and your existing scheduling workflow when you are ready to expand.

Before You Begin

Before setting up Instagram DM automation in BooSend, make sure you already have an Instagram post or Reel ready to publish, whether it is live or still scheduled. Your Instagram account needs to be connected to BooSend with the permissions required to publish content and reply to messages. If you manage Instagram with a team, confirm that the person building the flow has access to both Comment Automation and DM Automation inside your BooSend workspace.

Verify that Allow access to messages is enabled in the Instagram mobile app so BooSend can send DMs on your behalf. This is a one time setting inside Instagram's message controls. For platform level confirmation, check the Instagram Help Center.

How to Set Up DM Automation on an Instagram Post

When you create an Instagram DM automation in BooSend, you move through a short setup flow to choose the keyword trigger and define how BooSend responds when someone comments. You can attach one automation flow to each post or Reel, and BooSend handles the public comment reply, private DM, follow up messages, and even voice notes if you want a more personal experience.

The first time you set up DM automation for a specific Instagram account, BooSend guides you through a builder. After that, everything lives on one editable screen so you can launch new flows in under a minute.

Step 1: Select a Post and Set Your Keyword

Start by choosing the Instagram account and the post you want to automate, then define the keyword that triggers the conversation. Open BooSend and go to Instagram and DM Automation. Select your connected Instagram account, then choose the post or Reel from the list. Enter the keyword you want BooSend to watch for in the comments.

When BooSend sees that word in a comment, it triggers the flow. Keywords are not case sensitive, and you can add multiple variations such as INFO, info, or LINK. When everything looks right, select Continue.

Step 2: Define Replies to Comments on the Post

Next, create a rotating set of public comment replies that BooSend will post when someone uses the keyword. Adding multiple reply variations helps the conversation look natural to people browsing the comments. Review the suggested replies first, then edit or remove anything that does not sound like your brand voice. Select Add another reply to expand the rotation.

In most cases, add at least four or five variations so the comment section does not look repetitive. Add a short delay before the reply is published so the response feels more human. Once your replies are ready, select Continue.

Step 3: Create the DM

This is where you define the Instagram DM BooSend will send to anyone who comments with the trigger keyword. Write a short, conversational message that feels personal and clear. Add a call to action button label like Get the link or Join the waitlist, then paste the URL you want people to visit.

To improve conversions, attach an AI Voice Note or hand the conversation off to a BooSend AI Sales Agent that can answer follow up questions and help close the sale inside the DM thread. For paid offers, drop in a Stripe Payment Link so checkout happens inside the chat. After that, select Continue.

Step 4: Review and Activate

Once your keyword, comment replies, and DM are in place, review the full automation in the summary view and make any final changes. If everything looks good, select Activate to turn it on. If you are not ready to go live yet, select Save for later so you can publish the post first and enable the automation closer to launch.

How to Manage Your DM Automation Flows

After a flow is live, you can pause it, edit it, or duplicate it at any time, even after the post has been published. BooSend tracks the performance metrics that matter most for Instagram lead generation and sales conversations.

BooSend records how many comments on the post contain the keyword, how many DMs were sent, the DM open rate, link clicks from inside the DM, and replies or conversations that were handed off to an AI Sales Agent when that option is enabled.

To manage your flows, go to Dashboard and DM Automation inside BooSend. You see all your automations in one view, along with each post's status and live performance metrics. To pause a flow, use the Status toggle. To update the keyword, comment replies, or DM message, select Edit, make your changes, and click Save.

If a flow shows a Reconnect account label, Instagram's permission token has expired on Meta's side. Reconnect the account from your BooSend integrations page, and the label clears after the next DM sends successfully.

Why Automate Instagram DMs With BooSend

Instagram comment to DM automation helps you turn passive engagement into real conversations with potential buyers. Instead of manually replying to every person who comments on a post or Reel, BooSend responds instantly, keeps the experience personal, and sends people directly to the next step in your funnel.

For brands, creators, and service businesses, that means faster lead capture, more consistent follow up, and a better chance of converting interest into clicks, replies, and sales. To scale further, combine this setup with Instagram comment automation, Instagram scheduling, and a BooSend AI Sales Agent. The trigger surface is the Meta approved Private Replies feature.

FAQ

Can I attach more than one automation to a single post?

Each post or Reel gets one automation flow. Use keyword variations and branches inside that flow to handle multiple intents from the same post.

What happens to comments without the keyword?

They go untouched by the automation. You can layer in broader comment automation later if you want a default reply for every commenter.

How quickly does the DM send?

Within seconds of the keyword being detected. You can add a short delay if instant feels too eager for your brand.

Why is my flow showing a Reconnect account label?

Instagram's permission token has expired. Reconnect from the BooSend integrations page and the label clears after the next successful send.
