How to yncing Google Ads subscriptions to Klaviyo

Hi @Lily513,

Thanks for asking the community - let’s see if we can help.

When you mention “subscribers collected from Google Ads,” could you share a bit more detail on where these email addresses are currently being captured?

For example:

• Are they being collected via a lead form extension in Google Ads?

• Are they stored in another platform (like your website CMS or a CRM)?

• Or are you downloading them manually from somewhere in Google Ads itself?

Once we know how and where they’re being collected, we can better suggest the most efficient way to get them into Klaviyo - whether that’s via an integration, an automation tool like Zapier or Make, or a direct API connection.

Looking forward to hearing more!

Hi ​@ross_hopkins ,

Thanks for reaching out!

Yes, the email addresses are collected via a lead form extension in Google Ads. They are the potential customers and how can I sync them to Klaviyo?

That's a great question, and it's understandable you're looking for an automated solution instead of manual uploads.

What you're experiencing is a common hurdle because the primary direction for official integrations is usually to send data from a platform like Klaviyo to an advertising platform like Google Ads for targeting, which is what the article you found describes.

Getting subscription data from Google Ads into Klaviyo automatically requires a more custom approach since Google Ads isn't designed to directly export customer subscription data in real-time to an email service provider like Klaviyo in the way you're looking for.

A robust and automated solution involves a combination of tools, often centered around how the subscription is actually collected on your website.

The most reliable method is to use a server-side tracking setup facilitated by the Google Ads API, the Klaviyo API, Google Tag Manager (GTM), and a server-side solution like Stape or Google Cloud Platform (GCP).

Here is why this combination works well: When a user subscribes after clicking a Google Ad, the key is to capture that event and the collected email address as a conversion or subscription event on your website, usually through GTM.

Instead of just sending this data client-side to Google Ads for conversion tracking, you use GTM to send the event data to a server-side environment (Stape or GCP).

This server environment acts as a central hub.

From this server, you can use the Google Ads API to send the relevant data back to Google Ads to confirm the conversion, which is necessary for accurate ad reporting and optimization.

Crucially, at the same time, the server can use the Klaviyo API to send the new email address directly to your desired Klaviyo list.

This happens almost instantaneously.

This method gives you several benefits: it ensures you're sending high-quality, server-side data back to Google Ads for better performance, and it uses the powerful Klaviyo API to instantly add the subscriber to your list, avoiding manual work.

The event you'd be tracking in GTM and sending to your server and then to both APIs would be a Standard Event, perhaps lead or subscribe, which would contain the user's email address.

Using a server-side container on Stape or GCP offers the control and stability to manage these simultaneous API calls efficiently, making it a scalable and reliable way to sync your Google Ads-driven subscriptions directly into Klaviyo.
