Newsberry Email Marketing — Send Email Newsletters. It's a commercial product. Reasonably priced if you're into this sort of thing - $15 for 1,000 emailed newsletters for example. There is also Letterpop and this is a freebie. Alternatively, try vFlyer or Mailchimp.
This looks like a good service. I really like it that i can pay for the exact amount of mails i send. A+ for me!
