hello,
I can't find a method to do this without coding, however this could be a possible workaround.
Make sure that the RSS feed for the blog module is working correctly, and then go to
http://feedburner.google.comUse this service to create a feedburner RSS feed from your blog RSS feed.
Once you have created a feedburner account, go to the publicise tab and in there you can select to publicise via e-mail.
So, whenever a new blog post is created and your RSS feed is updated, feedburner will then e-mail the updated item.
To distribute to several e-mails, I would setup one e-mail address that auto forwards the email it receives to all of the collective e-mail IDs you require, so you then only need to set up feedburner to e-mail to one single e-mail address which will then forward this update to all of your collective IDs.
Hope this helps,
