I tend to use mailman for my newsletters. It has a templating system where you can modify the pages.

For example:

Give a shout if you need some pointers on getting the templates customised.

The only thing is you don't get things like hit ratios etc. You will have to track those yourself. Additionally, you have to worry about things like SPF and domainkeys.

I did some research, and there is PHPList which some people swear by, but I found it a bit clunky.
