Why "unknown" email addresses are created after migration to Shopify?

Why are "unknown" email addresses created after data migration to Shopify?

During customer data migration to Shopify using Cart2Cart, you might notice "unknown" email addresses in your Shopify customer list. This happens when the email address associated with a customer record in your source store is invalid or missing. Cart2Cart automatically generates a default email address in these cases to ensure the customer data is successfully migrated to Shopify.

This also applies to order data. If orders in your source store were placed by guest users (i.e., not registered customers) and are not linked to a valid customer account, Cart2Cart will create a default "unknown" email address for those orders during the data migration process.

Here's an example of how these automatically generated customer emails will appear in Shopify:

Understanding "Unknown" Email Addresses After Data Migration

These "unknown" email addresses serve as placeholders to maintain data integrity during the data migration. They ensure that all customer records and order information from your previous platform are transferred to Shopify, even if some data is incomplete or invalid.

Managing "Unknown" Email Addresses in Shopify

Once the data migration is complete, you can manage these "unknown" email addresses within your Shopify admin panel. You can choose to update them with correct email addresses if you have the information, or leave them as is. Remember to comply with all applicable data privacy regulations.
