I know it is frustrating, but hang in there. The emails from the Consulate are not a guarantee. Most people do get an email of receipt, then an email containing information about the outcome and the tracking number. Some people also receive an email stating that their application has been assigned to an ECO (before the outcome email). Once again, none of these are guarantee. In my case, an email of receipt and my passport with the visa was returned to me a couple days later. Somebody else on this board didn't even get an email of receipt, her package just arrived at her place 1 week after.
They generally return the documents & passport via UPS next day air. You will definitely get a tracking number, it won't be through the normal mail.
