Edit Email Text

PDF Creator v2.3 / Windows 7 Pro.

How do I format the text in the email body so that each paragraph is spaced and not look like a contiguous block? 

The text has been typed directly into PDFCreator and I’ve even tried inserting lines containing just spaces but the text in the resulting email body has no separators between the paragraphs.

I simply want the email message to appear like this message - with visual gaps between paragraphs
