I have been using it for a few months and it works fine, the only down side is that the free version doesn't give you all the reports needed to track your marketing efforts. But for newsletters and coupons to current clients, it's great. I've been using simplycast.com for my email marketing campaigns. The free version allows you to send up to 300 emails a month and for about $5 you can send 1000. It gives great reports, I can tell how many were actually opened, how many unsubscribed, # bounced, etc. And for 35% of your cost you can have the simply cast logo removed. That means if you buy the $5 package for another $1 you can have the simply cast link at the bottom removed.
