We used a free version with our previous web host, but have moved to go daddy and their Express Email Marketing program was a total disaster for us. We need one that is relatively inexpensive and easy to maintain and use for a non-technical person.

One that I've used it mail chimp. I think it might be www.mailchimp.com. I think you pay about a cent an email. They have a good html email set up section. If the website isn't right just search for mailchimp. make sure you don't spam, they'll kick you out pretty quick.
