They have to send us the code in an email and its the easiest way because do you really want it sent in the mail and then it get lost and the person dont write down the code so then you loose your xbox points and your listia points. So its just easier for the person to email it and then throw it away after the person who one leaves a feedback saying they worked. Dont ever give positive feedback unless you got the 1600 points on your xbox live account.
