Shopify Introduces defaultEmailAddress Field to Customer Object in 2025

What Changed

Shopify has added a new defaultEmailAddress field to the Customer object in GraphQL Admin API version 2025-04. This field enables developers to query a customer's email address along with their associated marketing communication state in a single, streamlined request. The addition simplifies customer data retrieval for apps that need to access and manage customer contact information and preferences.

Why This Matters

Previously, developers had to navigate multiple fields or make separate API calls to reliably retrieve a customer's primary email address and understand their marketing opt-in status. With this new field, you can now access this critical information more efficiently, reducing API complexity and improving app performance. This is particularly valuable for marketing automation apps, customer communication platforms, and loyalty programs that depend on accurate email data and consent tracking.

What You Should Do

• Update your GraphQL queries to use API version 2025-04 or later to access the defaultEmailAddress field
• Review your current customer data queries to identify where you can consolidate requests using the new field
• Test the new field in your development store to ensure it returns the expected customer email and marketing state data
