Hi everyone 👋

We’re excited to announce that you can now create Instagram Custom Audiences directly with Manychat 🎉

This powerful new feature lets you build live, first-party audiences of people who’ve interacted with your Instagram account connected to Manychat — and then use those audiences for retargeting inside Meta Ads Manager. The result? More precise targeting, higher ROI, and better ad performance.

✨ What’s New?

With Instagram Custom Audiences, you can now:

• Create custom lists of users based on Instagram Scoped User IDs (IGSIDs)

• Retarget warm leads and loyal followers with personalized ads

• Continuously update your ad audiences through automation in Flow Builder

• Build Lookalike Audiences in Meta Ads Manager to reach even more potential customer.

⚙️ How it works

There are two ways to set up Instagram Custom Audiences in Manychat:

1️⃣ Static Upload

Export a one-time list of users from your Contacts tab. Perfect for one-off campaigns like flash sales or product launches.

🔑 Things to know:

• Requires a Manychat Pro subscription

• Export includes only IGSIDs (not names, emails, or other details)

• IGSIDs are only available for contacts who have interacted with your Instagram account

• Don’t forget: you’ll also need your Facebook Page ID to set up the audience in Ads Manager

👉 Once exported, upload the file to Meta Ads Manager and create your Custom Audience. From there, you can also generate Lookalike Audiences to expand your reach.

2️⃣ Dynamic Action in Flow Builder

Automatically add or remove users from your Instagram Custom Audience in real time. Ideal for evergreen campaigns where your audience needs to stay fresh and updated.

Here’s how:

1. Open the Automation tab and create a new flow (or edit an existing one).

2. Add a trigger (e.g., user sends a message on Instagram).

3. (Optional) Add a Send Message block to engage users.

4. Drag in an Action block → choose Update Instagram Custom Audience.

5. Select Add or Remove depending on your strategy (e.g., add new leads to a “Warm Audience”).

6. Connect your blocks and Publish.

From now on, anyone who matches your trigger conditions will be added to (or removed from) your Instagram Custom Audience automatically.

🎯 Using Your Audience in Meta Ads Manager

Once your audience is ready:

1. Open Meta Ads Manager.

2. Go to Audiences → Create Custom Audience.

3. Select your Manychat-powered Instagram Custom Audience.

4. Use it for retargeting or build a Lookalike Audience for maximum reach.

⚠️ A few things to keep in mind:

Available only on Manychat Pro Only includes users who have interacted with your Instagram account
