I tried a couple free newsletter plugins, and they worked but were difficult to use, and one even had a problem with the unsubscribe feature that caused a lot of issues for us (it routed people to the wrong place and did not unsubscribe them). I was just about to purchase a package from Constant Contact when I decided to try this one. It's AMAZING. So easy. The newsletters look awesome and really professional. It's easy to import and export, easy to keep the list up to date and accurate, easy to manage multiple lists, etc. I feel like it's as good as my trial from Constant Contact was, the list is easier to mange because it's automated, and it's free!
