You already received a solid and accurate reply, but consider it as the headline equivalent of how you would structure a lengthy email you actually want the recipients to read. Firstly, you know the subject line is critical, but people will almost always glance at an email regardless. Secondly, you know you need short paragraphs or the wall of text will scare them away. Thirdly, you need to explicitly structure each paragraph with a strong subject -- either an easily parsable complete sentence or a bullet. Fourth, don't write it like you would a novel. Focus on facts and eliminate editorialization. Finally, close it with a call to action. Frankly, with the advent of Google Drive/Docs, I've started getting in the habit of putting all the meat of an email in a separate linked document and just placing the subject, intro and call-to-action in the body of the message itself. This is roughly how newspapers work, too.
