How to Connect Facebook Leads to Klaviyo

Transferring your leads from Facebook Ads to your Klaviyo account is one of the most powerful automations you can set up for your business. It turns passive interest from a social ad into an active, high-intent lead ready for your email nurture sequences. This guide will walk you through exactly how to connect Facebook Lead Ads to Klaviyo using two proven methods, plus some helpful tips to get the most out of your new setup.

Why Connecting Facebook Leads to Klaviyo Is a Must-Do

Before getting into the how, let's quickly touch on the why. Manually downloading CSV files from Facebook and uploading them to Klaviyo is a huge time-sink. Worse, it creates a delay between when someone expresses interest and when they hear from you. The goal of marketing automation isn't just to save you time, it's to create a better, more immediate experience for your potential customers.

By connecting these two platforms directly, you achieve a few powerful things:

• Speed to Lead: Your new subscriber gets a welcome email moments after they submit your Facebook form. This is when their interest is at its peak, and a fast response can make a massive difference in conversion rates.
• Seamless Nurturing: Leads automatically enter a tailored Klaviyo welcome flow, guiding them from social media browsers to loyal customers without any manual work on your part.
• Richer Customer Profiles: You can pass custom data from your lead ad forms directly into Klaviyo profiles, giving you valuable segmentation information right from the start.
• Saves You Time and Sanity: No more spreadsheets, reminders, or forgotten uploads. It just works in the background, letting you focus on crafting great ad campaigns and email content.

Two Main Ways to Make the Connection

There are two primary methods for syncing Facebook Lead Ads with your Klaviyo account. Both get the job done, but they suit different needs and levels of technical comfort.

1. Klaviyo’s Native Integration: This is the most straightforward method. Klaviyo has a built-in connector that allows you to directly link your Facebook Business account. It's designed to be user-friendly and handles the basics exceptionally well.
2. Using a Third-Party Automation Tool (like Zapier): Tools like Zapier, Make, or Integrately act as a middleman. This method provides more flexibility and power, allowing you to add custom logic, filter leads, or send data to multiple apps at once. If you need a more advanced workflow, this is the way to go.

We'll walk through both options, starting with the simplest one first.

Method 1: Using Klaviyo's Native Facebook Integration

This is the path most people should start with. It’s clean, simple, and maintained directly by Klaviyo. Follow these steps, and you'll have leads flowing in a matter of minutes.

Step 1: Prerequisites

Make sure you have everything you need before you start:

• An active Klaviyo account.
• An active Facebook Business Page with admin or editor access.
• An active Facebook Lead Ad campaign running with at least one active Lead Form. If you don't have one running, you must create one first inside of Facebook Ads Manager.

Step 2: Navigate to Integrations in Klaviyo

Log in to your Klaviyo dashboard. On the bottom left-hand side, click on your account name to open the settings menu, then select "Integrations." This is the central hub for connecting all third-party apps to your Klaviyo account.

Step 3: Find and Add the Facebook Integration

In the integrations directory, you'll see a search bar. Type "Facebook" and the integration should pop up. Click on it. You'll be taken to the Facebook integration page. Click the blue "Connect to Facebook" button.

Step 4: Authenticate Your Facebook Account

A pop-up window from Facebook will appear, asking you to grant Klaviyo permission to access your information. Make sure you are logged into the correct Facebook profile that has administrative access to your business page and ad account. Follow the prompts and approve the connection. It will ask for permissions to manage your pages and ads – this is necessary for the integration to see your lead forms and pull in new leads.

Step 5: Select Your Facebook Page and Map Forms to a Klaviyo List

Once authenticated, Klaviyo will show you a list of the Facebook Business Pages you manage. Select the page you’re running your Lead Ads from.

Next comes the fun part. Klaviyo will automatically detect the active lead generation forms on that page. You’ll be prompted to subscribe new leads from these forms to a specific Klaviyo list. For each form, select a destination list from the dropdown menu. This is where your new Facebook leads will live.

Pro Tip: It's a great practice to create a new, dedicated list in Klaviyo called "Facebook Ad Leads" or something similar. This keeps them separate and allows you to build specific welcome flows just for this audience.

Step 6: Map Your Form Fields

This is the most important configuration step. You need to tell Klaviyo where to put the data coming from Facebook. Klaviyo will show you the fields from your Facebook form (e.g., Email, First Name, Last Name, Phone Number) and ask you to map them to corresponding properties in Klaviyo.

Most standard fields will map automatically, like:

• Facebook Field: email &rarr, Klaviyo Property: Email
• Facebook Field: first_name &rarr, Klaviyo Property: First Name
• Facebook Field: last_name &rarr, Klaviyo Property: Last Name

If you have custom questions in your form (e.g., "What's your biggest business challenge?"), you can map these to custom properties in Klaviyo. Just give the new property a clear name (like BiggestChallenge) so you can use it for segmentation later.

Step 7: Launch Your Welcome Flow

With the integration active, any new leads from your selected forms will appear on your chosen Klaviyo list. The final piece of the puzzle is to engage them immediately. Create a new "Flow" in Klaviyo that is triggered when someone is added to the "Facebook Ad Leads" list. Your first email should be a warm welcome that delivers on whatever promise you made in your ad (e.g., link to a guide, discount code, webinar invite). The speed here really matters.

Method 2: Using Zapier for More Advanced Connections

Do you need to add a custom tag based on the ad campaign? Want to send a Slack notification to your team whenever a high-value lead signs up? This is where an automation tool like Zapier shines. It gives you an almost limitless level of customization.

Step 1: Set Up Your Accounts

You’ll need accounts for:

• Facebook (with an active Lead Ad form)
• Klaviyo
• Zapier (the free plan is often enough to get started)

Step 2: Create a New "Zap" and Set Your Trigger

In Zapier, click "Create Zap." Zaps consist of a "Trigger" (the event that starts the automation) and an "Action" (what happens next).

• For the Trigger app, choose "Facebook Lead Ads."
• For the "Event," select "New Lead." Click continue.
• Connect your Facebook account and grant Zapier permission.
• In the "Set up trigger" step, select the Page and the specific Form you want to get leads from. If you want this to work for all forms on a page, you can leave the form field blank.
• Click "Test trigger." Zapier will pull in a recent or sample lead from your form to verify the connection is working. This is a great way to see exactly what data is coming through.

Step 3: Set Up Your Action

Now, you'll tell Zapier what to do with that lead data.

• For the Action app, choose "Klaviyo."
• For the "Event," select "Add Subscriber." This is the most common use-case. Click continue.
• You'll be prompted to connect your Klaviyo account. This usually requires a Private API Key from Klaviyo. You can find this in your Klaviyo account under Account &rarr, Settings &rarr, API Keys. Create a new private key named "Zapier."
• Paste the key into Zapier to complete the connection.

Step 4: Map Fields From Facebook to Klaviyo

This step mirrors the native integration process, but you have more visual control within Zapier. You will see fields for the Klaviyo subscriber profile and can pull in data directly from the Facebook "trigger" step.

• For "List," select your target list in Klaviyo.
• For "Email," click the field and select the Email property from the Facebook Lead Ads data.
• Match other fields like First Name, Last Name, and any custom questions to their Klaviyo property counterparts. You can even combine fields or add static text here.

This is where you can do cool things Zapier lets you do. For instance, you could map the Facebook ad_name or campaign_name to a custom property in Klaviyo called lead_source_campaign. This gives you unbelievably powerful data for segmenting your audience and understanding your ad performance.

Step 5: Test and Turn on Your Zap

Once you’ve mapped your fields, click "Test & Continue." Zapier will send a test subscriber to your Klaviyo list with the data from your sample lead. Pop over to Klaviyo to confirm it came through correctly. If it looks good, publish your Zap, and you're set!
