If you're running paid advertising campaigns, there's no excuse for the tedious process of exporting customer purchase lists and manually re-uploading those CSVs to your social advertising platforms.

If you're using Klaviyo for your email marketing, there's a much better way to manage your customer data across Meta's advertising platform.

👉🏼 [YouTube Explainer] – Using the Klaviyo × Meta integration

Setting Up the Klaviyo-Meta Integration

Navigate to the integrations section in the bottom left-hand side of your Klaviyo interface and add the Meta Ads integration. Once connected, you'll discover two powerful mechanisms that can transform how you manage your advertising audiences.

Custom Audiences: Set It and Forget It

The custom audiences feature allows you to sync your Klaviyo segments directly to individual custom audiences in Meta. This creates a dynamic, automated connection between your email platform and your advertising accounts.

Here's what makes this so valuable: as new individuals are added to any given list or segment in Klaviyo, the integration automatically pushes updates through an API to refresh the corresponding audience in Meta.

This automation is particularly useful for:

  • Past purchaser lists - Improve your audience definitions with accurate customer data
  • Lookalike audiences - Build better lookalikes based on your actual customer segments
  • Exclusions - Prevent wasted ad spend by automatically excluding past customers from acquisition campaigns

The custom audience sync via API is a no-brainer upgrade to your current workflow.

Lead Ads: Capture and Sync Automatically

The second mechanism available through this integration is the lead ads section. If you're running Meta-native lead forms to capture email addresses, you can connect those forms directly to specific Klaviyo lists.

This means when someone fills out your lead form on Meta, their information automatically flows into your designated Klaviyo list. No manual exports, no CSV files, no data entry delays.

The Bottom Line

There's simply no reason to manually export and import data between these platforms anymore. The Klaviyo-Meta integration handles it all automatically, saving you time while ensuring your advertising audiences stay current and accurate.

You'll find everything you need in the integrations tab of your Klaviyo account. Set it up once, and let the automation work for you.
