This is endlessly discussed every year. General consensus is there are several marketing emails that go out to everyone in batches over a few days.
There are only 3 targeted emails: Alumni Scholarship Invite (goes to quite a few but not everyone), Regents Invite (goes to top 1-2%), and Discover Engineering (goes to top engineering applicants a week before decisions).
All other emails are general marketing and have no bearing on your status.
