I once used a plugin called Chimp Express for Wordpress to compose campaign directly from Wordpress. The benefit from using this plugin was that it was very easy to compose campaigns. It worked well until Wordpress 3.3.1 arrived. After this update it no longer seems to function. The support for this plugin is dead, and it doesn't seem like no one is picking up the development.
Do you know any good plugins that can achieve the same?
