Do not promise too much (create e-mail)

I have been working a bit with the plugin but I find that you promise too much in the sense of being able too create the content of a newsletter.
Example: https://premium.wpmudev.org/wp-content/uploads/2011/07/Content-e1310555655958.png
No way floating images left or right inside the text will work in the content of the e-mail.

Since you use the normal content editor you make users think that they will get a nice layout, but you are surely aware that those layouts (css) will work in a browser but not in many email clients.

I think it would be good to warn users for those problems...
