Write a letter by hand and address it to the CEO of the company. It'll have much more of an impact and will definitely reach the ears of the employee you recommend as well. I heard of this happening a number of times in Royal Caribbean where a staff member went above and beyond, a family member was working there and received a number of these types of letters; apparently they went straight into the employee's file and definitely impacted their promotion opportunities (in a good way).
