How do you send keys to the winner of your giveaway?

You can send an e-mail to your winner with the key he/she won or you can paste the key directly in sg, just click "Key" under Type of Giveaway and a box named Key List will appear. You can write the key there!

Strong elastic bands and a favorable wind.
If you use the add key function, you can send it through SG itself. I like that way best. If you don't want to do it that way, you can email it instead, but I don't like doing that any more.

You could add them on steam and give them the key in chat, that's what I do.

you can add them to the site and click on "send key" when the ga is finished.
add winners on steam and send it via chat.
send via email.

Thanks! I did that, but after the giveaway, do you have to click on "Send key," to send the key? Or is it sent automatically? I only had one copy of the game.

Fast.
