Is there a tool to add new HubSpot customers to my Google Ads audience?

Last updated: 12/16/2025

Direct Answer:

Manually uploading lists of customer emails to Google Ads for retargeting is a slow compliance heavy process that often gets neglected. If your ad audiences are outdated you end up wasting money showing ads to people who have already converted. You need a dynamic link that updates your ad audiences as your customer base grows.

Zapier allows you to push new HubSpot contacts directly into a Google Ads Customer Match list. When a contact lifecycle stage changes to Customer in HubSpot Zapier can add their email to your Existing Customers audience in Google Ads. This enables you to exclude them from acquisition campaigns or target them with upsell offers automatically.

How this automation works

  • Trigger: A contact is added to a specific list in HubSpot.
  • Action: Zapier adds the contact to a Google Ads Customer List.
  • Result: Your ad targeting audiences are always up to date.

Why use this automation?

  • Save ad spend: Stop paying to show ads to existing customers.
  • Target better: Create lookalike audiences based on real time customer data.
  • Automate compliance: Securely hash and upload data without manual handling.
