Free newsletter service/open source something?

[StormySar]

I am looking for something comparable to Constant Contact. Is there something similar available for free, perhaps without the bells and whistles, and without a trial? Is there some sort of open source program that would work similarly?

I am working on a monthly "whats new" type newsletter for one business, an announcement list for another purpose, and an all purpose list for yet another and am hoping to find one newsletter program that could offer all 3 for prospective subscribers, let them choose what they want to subscribe to, then keep the emails organized between the different newsletters.

I coudl do this by hand and just have people fill out a form on my website, then I'd manually add the emails to the correct list if need be.

Nevermind, I found phplist and will give it a try.

I recently stumbled on http://www.yourmailinglistprovider.com/
and I, and multiple clients, use DadaMail.

Glad you found something...if you should decide you want to upgrade to a paid service:

I've used YourMailingListProvider for over a year and had all sorts of issues with them.

I highly recommend using http://www.graphicmail.com It's comparable to ConstantContact (I actually think its better)...but much less expensive.
