Stop Wasting Ad Spend: Automate Your Shopify Customer Exclusion Lists
Are you wasting your marketing budget showing new customer acquisition ads to people who just bought from your Shopify store? When a customer converts, they are often correctly removed from your Google Ads audience, but a delay in updating your Facebook Custom Audience means they continue to see irrelevant ads. This lag leads to wasted ad spend, a frustrating experience for your new customers, and skewed performance metrics.
This playbook details 'The Shopify E-commerce Stack,' an automated workflow that instantly synchronizes your customer data across your advertising platforms. When a new customer completes a purchase in Shopify, a Zapier automation immediately captures the customer's data, securely hashes it, and adds it to exclusion lists in both Google Ads and Facebook Ads. This ensures that once someone becomes a customer, they are instantly removed from all new customer acquisition campaigns, saving you money and improving their post-purchase experience.
Expected Outcomes
- Drastically reduce wasted ad spend on existing customers.
- Automate audience management to save time and prevent manual errors.
- Improve the post-purchase customer experience by eliminating irrelevant ads.
- Increase the accuracy of your ad campaign performance data and ROAS.
- Maintain perfectly synchronized exclusion lists across Google and Facebook.

The Workflow
Integration Logic
-
Zapier
Zapier operates on a trigger-and-action model to connect applications. This integration allows HubSpot to function as either the trigger or the action. As a trigger, an event in HubSpot (e.g., a new contact is created, a deal stage changes) initiates a workflow. As an action, an event in another app (e.g., a new entry in a Typeform, a new row in Google Sheets) causes a corresponding action in HubSpot (e.g., create a contact, update a deal). This enables a bi-directional flow of data, automating tasks like lead entry, data enrichment, and internal notifications.
