How to expluce a post from email list?

I have a post of administrative nature, which should not be sent to the email subscribers. How do I post such a post without email subscribers receiving a copy of it? Thanks!

I hope I found a trick, if anyone care to check?
First publish as an anonymous post.
Edit the post. Go onto edit the date of the post to a date far in the past (I put a date beginning of the year).
Publish the date updated post, still in anonymous mode.
Move the post from anonymous to the blog you want.
