Wanted to contact you to let you know we’ve gone with another candidate for the [job title] position.  I really appreciate you taking the time to come in and interview and you were a top candidate (out of 300 resumes and 12 interviewees).  If you don’t mind I’ll keep your resume on hand and if anything opens up in the future I’ll certainly contact you.  Otherwise, wish you good success in the future and hope 2013 is a great year for you.

Thanks again and best wishes,
