How to Accept Email Address Changes from Customers on Shopify

Tsun ライターチーム

When running a Shopify store, you'll sometimes get inquiries from customers saying "I'd like to change my email address." If you're currently handling these manually from the admin, each inquiry adds to your support workload, and customers are left waiting for a response. However, by making use of Shopify's new customer accounts feature or a Shopify app, you can set up an environment where customers can change their own email address.

This article introduces the benefits of letting customers change their own email address, specific ways to do it, and recommended Shopify apps.

Benefits of Letting Customers Change Their Own Email Address

Reduced Support Workload

Every time a customer submits an email-change request, support staff have to handle it manually from the admin, which takes up a lot of time. If you introduce a mechanism that lets customers make the change themselves, you're freed from this kind of routine inquiry handling and can focus on more important work.

Improved Customer Convenience

Previously, if a customer wanted to change their email address, they had to contact the store and wait for support staff to handle it. With a feature that lets customers make the change themselves, they can update it instantly from their account page at any time, 24/7, even outside business hours or on holidays — greatly improving the customer experience.

A More Efficient Email-Change Process

Manual handling requires multiple steps — receiving the inquiry, verifying identity, making the change, and sending a completion notice — which also carries a risk of human error. With automatic identity verification via a confirmation code and automatic logging of the change history, the whole process becomes standardized, improving both security and operational efficiency.

How to Let Customers Change Their Own Email Address

How you let customers change their own email address depends on whether you're using new customer accounts or classic customer accounts.

If You're Using New Customer Accounts

If you're using new customer accounts, an update released on October 9, 2025 made it possible to let customers change their own email address with no additional configuration required.

Features

  • No setup required if you're on new customer accounts
  • Robust ownership verification (a one-time passcode is sent to the new address)
  • Customers can change their email address while staying logged in

How Customers Change Their Email Address

  1. Go to your account page
  2. Click the account icon
  3. Click "Profile"
  4. Click the edit icon (pencil icon) next to your account name
  5. Enter your new email address in the email input field
  6. Click "Save"
  7. A one-time passcode is sent to the email address you entered — enter that code
  8. Click "Verify"

If You're Using Classic Customer Accounts (Previous Version)

If you're using classic customer accounts (the previous version), there's no built-in feature that lets customers change their own email address.

Because of this, you'll need to either customize the source code or use a Shopify app.

In Closing

How you go about accepting email address changes from customers on Shopify depends on the version of customer accounts you're using. If you're using new customer accounts, the October 9, 2025 update made the feature available with no setup required.

On the other hand, if you're using classic customer accounts, you'll need to either customize the source code or introduce a Shopify app.

By setting up a mechanism that lets customers change their own email address, you can achieve both a reduction in support workload and improved customer satisfaction at the same time. Choose the approach that best fits how your store operates.
