I'm looking for a wordpress plug-in or tool that can allow an editor to select certain posts to include in a newsletter template. The tool would place snippets of posts into the newsletter template along with thumbnails of the images. We would then be able to take the HTML and broadcast it out through a separate e-mail broadcaster.
NOTE: I am NOTe looking for a mail management tool (like Mailpress) but rather a tool that will create an e-newsletter based on the posts in a blog. E-mailing this HTML will be separate.
