To send the email, we have a custom mailer we wrote in house to suit our purposes. It includes tracking functionality, etc. There are many, many services out there for doing bulk emailing. Google for "bulk email software" or "bulk email services".
We designed a custom template for the client (they didn't like the ones provided by the service provider) and they have had a pretty good open rate and decent click through rate on links. There are a few things I don't like about this specific provider's interface, but overall it seems easy enough to use for a small mailing list, and I think it's free if you're under a certain # of users (also has a free trial).
We used the free trial a few months back ourselves when there was a big DNS mixup with our emails that had everything bouncing (since messages from an outsourced provider aren't through our email system/DNS server they got through) and a few clients even commented on the nice look/feel of the message.
I think an outsourced service like this is a good way to do the first couple of issues of a newsletter to see what type of response you get -- that way you can test how the content and your mailing list responds before you spend time learning software or setting up systems in-house. I usually recommend clients go with the "outsourced services" route for trial runs and testing of anything new, just because I've spent a few too many hours uninstalling crappy software from client systems (sigh) and listening to clients whine about how much time they put into learning software that doesn't do what they realized they really want once they got into doing the project (double sigh).
I like the fact that it can send timed messages, i.e. you already have a queue of message lined up, and as soon as someone signs up for your newsletter it will start the sequence, i.e. one promotion, then another 3 weeks from then, and another a couple of days from then... whatever intervals you want to set up.
Alternatively you can send broadcasts to imported emails whenever you want, which is what i use for the newsletter.
Really quite good.
