You will need to go into your Bungie profile settings and update your email in the Notifications & Email tab. After you have completed that, visit your rewards page here: https://www.bungie.net/rewards Click the Email Discount Code button for each reward you are wishing to redeem. If you are having trouble receiving email from Bungie, make sure you check your spam folder as they may be filtered there. If that doesn't work, your email provider may be blocking email from Bungie. If that is the case, I recommend that you set up an email address with another vendor, such as Gmail, and have your reward codes sent there.
