How to setup Newsletter plugin

How to setup the newsletter plugin because i can’t make working it…

Looks like this plugin hasn’t been updated for 3 years. You might want to contact the developer and ask if it’s still compatible. Otherwise you should post some more details. Do you get any error-messages?

The problem is that this is not really a plugin, you have to put all the required files/folders into a starterkit/your project, manually (if it still works, anyway).
