I got the same email which made me think "Yay, I get a beta helmet!" but on rereading it I think they are simply saying "this confirms that you contacted us and we wanted to let you know that we got the submission and will be selecting people soon".
So, if you think you applied and didn't get the email, I think that may mean that your request may have gotten lost in transit? Or maybe the confirmations are just going out slowly as they process them into their selection database?
Mine arrived on the 24th.
