For help, I bought direct mail from Japan and received such a short message.

Generally speaking, after you place an order, Riya will send you an email to confirm the order information. It has not been delivered at this time. You can modify or cancel the order, and then Riya will send you an email again. At this time, it has been delivered. The text message or email that comes later is the express logistics company of the carrier, which may be ekman, DHL and so on. It is mainly for you to submit customs clearance information, such as detailed information of purchased goods, pictures on the front and back of your ID card, and reply to emails as required.
