Thank you for getting in touch. If you are not sure which email address you used when setting up the store, you can head to our account recovery page and enter in some of the different email addresses you may have used. An email will then be sent to the email addresses you enter in with a list of stores that have this email attached to them.
If you are still not able to find and access your store after trying this, please contact our support team directly. They will be able to look into this for you and will guide you through the process of recovering your store.
