Now there’s a new player in the game called FeedMyInbox which works more or less the same as above mentioned services but offers some distinct advantages:
For instance, you may supply the address of a website that doesn’t have feeds (e.g. google.com) and Feed My Inbox will automatically suggest related feeds like the official Google blog, Google News, etc.
And incase a page is associated with multiple feeds (say, CNN or Yahoo! News), you’ll get a list of options to choose from – you can either select one or multiple feeds and they’ll come to you as an email digest with all that news that was published the previous day.
Nick Francis of Feed My Inbox says that "each time a user enters a site that cannot find a feed, our team gets an email. We go check it out for ourselves to try and attach a feed to that site if applicable so that anyone entering that site in the future gets a successful message."
