As far as the Spam goes, that is because of your email client and has nothing to do with CSS Form Builder. A lot of times, many clients and email servers look for certain words and content. My guess is the fact that it is coming from an email address named "test" and with a bunch of Lorum Ipsum fill text, that the email client just thinks it is Spam.
To get rid of the fill text, you should be able to edit the template after selecting it and get rid of the fields you don't want. The templates contain several populated fields just for example reasons but those fields and rows can be completely removed.
