Please! Help Me! How to send a steam gift, If I only have the game code?

private gift to me of course lol

You can't. Send the winner the key.

Email the winner the code...

You cannot send a Steam gift by using a CD key. You can email the person the code, or message them over Steam, etc.

I email my keys to the winner, and I've received keys via email from the giveaway hosts! So just email to the provided email.:) Or add them on steam and send via chat.

Thank you all! You are the best!
