Clean and User Friendly

I use the free version of this plugin and haven’t had any problems. True, it’s a bit limited as far as customization to the newsletter, but it’s clean, lets you add posts and images, offers features like viewable stats (such as opens, clicks, and unsubscribes), creation of separate email lists, subscriber maintenance, forms creation, and–being wysiwyg–it’s extremely easy to use. I use this plugin for small email lists on a personal (sort of work) site and am pleased with it.
