Should've been a text message. A canned message about the vehicle leaving Fremont and being in transit to the delivery center.
Mine came 2 days after I got the VIN.
Hi **NAME**, your Model Y has just departed from our factory and is in transit to your delivery center!
Be on the lookout for a message within the next week to schedule your delivery appointment. When you receive that message, be sure to schedule as soon as possible, as appointments fill up quickly.
