Never recieved emails for s4 and s5 gift claim codes?

Did anyone else just never recieve an email for the gift codes at the start of s4 and s5? I had no idea there were any codes, I thought they just stopped doing that. Apparently I just don't get them anymore? I got the s3 code, and I double checked to make sure my email is verified and I even have both the promotions and survey boxes ticked. Nothing in my email for s4 or s5, I even checked spam and promotions boxes.
