Feedburner is a well known service for managing and maintaining your sites RSS feed and email subscription options.
It started out as an independent system but was bought out by Google and integrated into the Google tool set in 2004 for an estimated 100 million dollars. Incredibly popular, and with a wealth of options it is recognisable by the distinctive icon of a flame on a blue circle.
