Nvidia Graphics Cards Skin, where is the code?

I bought a 1070 Ti graphics card in which the Fortnite bundle is also available, but I do not know how I can redeem the bundle or where the code is.

Do you usually get as a mail to the address that you have specified when buying.

Thank you

And which I find in gmail or email?

You can find them in your mail program. Possibly. Also look under spam
