We have Newsletter Studio setup to send from Content Nodes - that works fine for published content.

However, it would be great if a newsletter could be previewed and/or a test email sent using the saved - but not published - content.

The problem we have is that newsletters also appear on the website, so when creating a newsletter, it has to be published (which means it appears on the website) in order to test how it looks via email.

Is there a solution for this? Or a viable workaround?
