Need to be able to post to blog category and e-mail newsletter to subscribers

We have a wordpress site which has a "devotional" category for posts which show up on a Devotional page on the site. We need to have newsletter functionality so that when a post is created for the devotional category, it also emails it as a newsletter. Alternatively, if we could have it so that we send out a devotional newsletter it also posts it to the devotional category, that would also work. Can your plugin do this? Thanks
