First check whether an order has already been placed with the e-mail address. If not? Place an order first before you can create an account.
Have you already placed an order?
Then check the following steps:
1. did the email end up in your spam or junk mail folder?
2. have you entered the correct email address?
Did you log into the online store with your Apple ID?
When you sign in with your Apple ID, we receive an encrypted email address with your order. This means that we cannot reach you at that address. Would you like to verify this email address and provide us with your own email address? You can find it on the payment summary you received from us by email.
