How will Black Ops 3 PC Beta be delivered?

[DonPapayo]

Hi! I've already redeemed my Black Ops 3 Beta "mother-code" (the code of 13 characters) on the Call of Duty website. Now I have to wait to August 26th (just like Xbox One users) to be able to get my 3 beta codes. But, when I redeemed my "mother-code" for PC, the page showed the August 26th those beta codes which I said before, will be delivered by email to Xbox One users but it didn't say anything about us, the PC users.
For that reason, I'm asking how will us receive the codes for Beta.

PD: Could be possible that Betas will get activated automatically on the account we were logged into when we redeemed the "mother-code"? And if it is finally by this way, how will us get the another two codes for Beta that Call of Duty gives us for our friends? (On PS4, "mother-codes" redeemers received 3 codes for BO3 Beta, one for themselves and two more for their friends.

Thank you all guys and sorry for my bad English, I'm Spanish! =)
