Since you are writing for reporters, you should write like reporters. They often use an inverted pyramid to present information. With the inverted pyramid, the most basic and important facts are placed at the top of a story so someone who reads only the first few paragraphs will know the most important facts.
More detailed information is presented as the reader progresses into the story.
A good news release should use that style. Edit your copy to remove excess words and puff terminology. Try to keep your message on one page. Be absolutely certain that every fact and title in the release is correct and that every name is spelled properly. Check the copy closely for grammatical errors.
