'Asynch UI' has its uses but, in case of email, I don't think benefits to users have much substance. Yes, perception is a critical design factor we must all deal with on daily basis but we shouldn't forget that 'magic show' entertains at best and offers no real value to users. 'Magic' by another name is hoodwinking and can easily induce confusion and anger when misapplied.
