Get keys on Desura?
Indie Royale Steam keys are usually added on Desura first. They must be obtained through the client not the web version, or you will get an error message.You can find the keys within Desura through various links, the easiest would be to use the Menu (click the Desura icon next to the profile picture), and then navigate to Tools->List Games & Cd Keys.

Email the developers, or publishers?
Whenever you are sending out requests for a Steam key be sure to include copies of any proof you have of buying the game(s). A purchase receipt, a screenshot of the bundle, a link to your profile (steam/desura) are the most common basic requirements. Do try to keep your emails brief, and to the point, as they will probably get overwhelmed with requests. Wishing them luck, and thanking them won't hurt though.

*Unless stated otherwise all reported keys are Steam keys.
