I recently read the book titled "Send" at the recommendation of my friend Matthew. It's a short book by David Shipley and Will Schwalbe and currently rates 4/5 stars on Amazon from 31 reviewers. This is an easy-to-read and funny outline of etiquette for email. I recommend this book to everyone. I've received my share of email that is poorly written to the point of being ineffective at communicating. I'd like to believe that I'm pretty good at composing emails, but I probably have my lapses like everyone else. It's good to review the basics and this book does a decent job of that.
