How can i send gift?

e-mail or through steam

You have to either add them through Steam or send it to their e-mail, which is shown to you and only you on the "View Created" page.

You either contact the winner through Steam or send an email to him with the key (Steamgifts will show you the winners registered email), there isn't any way to give the key through the Steamgifts website if that's what you're looking for.

Oh thanks i didn't know that. :D
