No email in inbox

I’ve been patiently waiting for my email regarding the specialization code unlocks but, still haven’t seen it. Spam folder is empty, inbox is empty, and I’ve been a player since Nov 6. Is there a chance that I didn’t get it or whoever is sending out hasn’t gotten to my email yet? I wouldn’t be able to tell if it had been sent to me so advice or contact information about who to talk to about how to check would be extremely helpful.
