There's a whole pile of RSS-to-Email services out there, but if anyone can break into the market it's FeedBurner, and to that end they've launched FeedBurner Email. It's a new service for publishers that lets readers get updates in their e-mail inbox rather than a feed reader. FeedBurner founder Dick Costolo says it's "largely 'brandless,'" meaning the e-mails that arrive don't look like they were delivered from your web site, not FeedBurner. Furthermore, publishers have access to subscribers' e-mail addresses (so they can leave FeedBurner Email and move to another service without a fuss) and, most impressively, the service is free.
