This video is a presentation from the weekly Umbraco show uHangout.
This video shows an introduction on how to use Newsletter Studio and goes through the basic features
If you want to list your newsletters on the website, or if you just want to use umbraco templates,
documents and data types as your content source, you can send the newslettes from the content
section of Umbraco.
If you need to process the content of your newsletter you should use a render task. This will give
you the newsletter mail message and you can process it in what ever way you want.
