Spotify Premium Message

A few weeks ago I received a notification about the Spotify Premium code being sent to me. Having recently decided to get the most out of the deal, I tried to locate the code by checking both through my emails and my Xbox beta app notifications, but couldn't
seem to find it. I may have accidentally deleted the email, but couldn't locate the notification on Xbox as it may have also cleared. If I could have the email/code resent to me, or if someone could tell me how I could access it another way, I'd be grateful.
