Can I configure my Wordpress site to send out email notifications when new material is posted

I'm new to Wordpress and when I google my question, I get a variety of possibilities, but I'm thinking I'm doing well to ask an expert directly and get a specific response.

My client wants to be able to post info on his Wordpress site and simultaneously generate an email informing all registered users that there's a new piece of information for them to consider.

Is that a plugin? Is that something you can rig on the Dashboard? How would I pull that off?

Thanks in advance.
