This short book provides a general overview of how email communication should be approached. I draw parallels between email and the traditional U.S. postal system, highlighting the importance of structure, clarity, and etiquette. I emphasize why email matters and explain the essential manners that should be consistently practiced at every level. From a business standpoint, an email often reflects the company’s outlook, professionalism, and management style. Because of this, we must exercise care and precision in our messages. In this book, I discuss the impact of emails—both good and bad—and the lessons to be learned from them. With an Associate Degree in Business Management Technology, I draw on my education and experience to provide practical insights throughout this work.
