Where is my code ?

Hello Mojang, recently i have register for Minecraft earth. I have received the message who say "you are now registered to minecraft earth. For claim your special skin, copy the code and go here : GET MY SKIN" (this text is approximately the message, i'm french so sorry for the mistakes if they are) and... i don't see any code, nothing in my messaging, and nothing in the web version of this message (the link who say : "display in a browser"). So, i think it's a bug, and i don't want that this happens again for another person's. Thank you.
