Email Template: How to request your developer to add New Customer Data for Google Ads

Hi {First name of your developer},

I need your help configuring the New Customer data feature for Google Ads. This feature allows us to distinguish between new and returning customers, analyze performance more accurately, and maximize conversion value specifically for new customer acquisition.

Below is a short briefing explaining what needs to be implemented.

1. Add the new_customer Parameter to the Google Ads Conversion Event

We need to extend our existing Google Ads conversion event snippet by adding a new parameter called new_customer.

This conversion event fires on the following page(s) or event(s):

  • {Insert page URL(s) or event(s)}

2. Logic for the new_customer Parameter

The new_customer parameter accepts a boolean value and must be populated dynamically based on whether the customer already exists in our database.

Accepted Values

  • true → New customer (email address not found in the database)
  • false → Returning customer (email address already exists in the database)

Please ensure that the logic determining this value runs before the Google Ads conversion event fires.

3. Example Event Snippet (For Reference Only)

Below is a dummy example showing where the new_customer parameter should be placed in the conversion event snippet.

Important: This example is for illustration purposes only. Please do not copy or replace the full script as-is.

<script type=”text/javascript”>

  gtag(‘event’, ‘conversion’, {

    send_to: ‘W-CONVERSION_ID/CONVERSION_LABEL’,

    value: ‘VALUE’,

    currency: ‘CURRENCY’,

    transaction_id: ‘TRANSACTION_ID’,

    new_customer: true /* populate dynamically with true or false */

  });

</script>

4. Validation & Next Steps

Once the new_customer parameter is successfully implemented and firing with the conversion event, I’ll validate the setup within Google Ads and complete the remaining configuration on my side.

If you could notify me once this change is live, that would be great.

If you have any questions or need clarification during implementation, please feel free to contact me.

Best regards,
{Your name}
