I do not send out newsletters from my hosting site but I do have a contest site that I do send out weekly newletters from. I don't think I could come up with enough new information to send out a newsletter from my hosting site. But the software that I use on my other site is pretty good. It is a double op-in program that you can get for free if you only have one newsletter and want to send it out in text. There is a subscribe page or box that you can put on your site. The software is called subscribe2me. Take a look at it I like it and you cant beat the price if you only need one list and use text newsletters.
