Via TechCrunch -- FeedBurner has launched a new service called
FeedBurner Email. The service is a feed-to-email-service that allows publishers the ability to offer plain text or HTML emails containing the latest posts to their subscribers. It's a publisher-only service, where the emails are delivered as "from" the publisher, not from FeedBurner. There's not a FeedBurner header and only a small "delivered by" footer. Publishers will be able to access to the email addresses that subscribe to their feed, so they could export these addresses in order to move from FeedBurner to another service, if they so desired.
If you're a publisher who wants to use this new service, just log in to your FeedBurner account and click on the Publicize Tab. There is an Email Subscriptions option on your left. You click on the "Activate" button and FeedBurner will generate some code for you to copy & paste to your blog. However, TypePad users can just add the widget (thanks, TypePad!)
