Hi Jeff,
You can get stats on email subscribers on the FeedBurner control panel. If you have enabled click and/or view tracking, views and clicks from email subscribers will also be counted (though views might not be counted if the user's email client blocks loading of external resources).
Maybe you already knew this, and what you really want is the stats from FeedBurner to be merged with the stats from Blogger: I'm sorry to say there currently is no easy way to do this.
