Well, there are a couple I'm aware of. A search of snowcovered will show them. I've personally used two and can claim mixed results, and not all the problems are someone the module developer can help you with. If it's any indication, I'm using Constant Contact myself even though I own two other DNN mailing list packages. It's not like I just dropped out of the bulk email tree yesterday either, for many years I managed the promotional emails for a major airline and we were shipping out several million emails a week.

Before you decide to go local with your emails for off make sure you don't violate the terms of your hosting agreement. Many specifically prohibit bulk email. Others may limit the number of emails per hour you can send. Will your ISP support your bulk email efforts? For example big ISP's end up on a lot of SPAM block lists because spammers will set up domains, blast a bunch of email, then disappear. Because of this places like AOL Yahoo, Hotmail, and many others will have white lists, black lists, and grey lists. It can be a lot of work to be able to get email delivered from your domain to lots of others by getting your domain on the right white lists, off the black lists, and through the probation period of the grey lists. 

SO before you grab a package and cancel that listmailpro service, make sure you understand what you're getting into. It's not just a matter of installing the software, loading your list, and letting things fly.

Hi, I'm trying to use constant contacts, but when I put the code in (for users to sign up for it) the <form> stuff seems to mess up the page.... sending my right pane to the bottom of the page.  How do you do it?  Thanks in advance for any help.

This is what I've pasted in:

<div align="center">
