Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureThis app is for merchants who don't want Shopify's default behavior of automatically updating the customer's default address to the shipping address. It triggers upon an order and updates the customer's default address to the billing address. It utilizes customer information like address, name, and phone number, securely stored on Shopify's servers, with the app not retaining any information.
With this app you can enable users to change their email address on their own! You will no longer have the trouble of dealing with e-mail change inquiries. It adds a link for "email address change" on My Page account information. A confirmation code will be sent to the new e-mail address and will be completed after verified.
- Prevents changes to the default address on orders.
- Easy to use because it works as part of the Flow functionality.
- Safe to use as it does not store customer information.
- ユーザーによるメールアドレス変更を可能にします
- 管理画面から簡単に、マイページにメールアドレス変更機能を追加することができます。
- メールアドレスの変更は、コードによる認証で行います
