Good Advice. And it's something you can do, too. Click on the link for the whole article.
In the article the author, Alexis Kleinman, explains why successful people send very short emails:
1. People don't need as much background information as you think they do. It might seem essential to you, but it actually seems superfluous to the email recipient. They'd rather you get to the information and request more quickly, and then they can ask you to fill in any holes in their knowledge later.
2. Don't waste your subject line. In many email services, including Gmail, just the subject line and first line or two is visible in the recipient's inbox. Why make the subject "Hi" when it could be "Dinner on Thursday?" Give the recipient an idea of what the email contains and a good reason to click on it.
3. Just because your email is short, that doesn't mean it has to be rude."No matter how short your emails, there is a way to inject a friendly, cheery note, and don't forget to do that. Short doesn't mean that it's okay to go around barking orders," Schwalbe says.
I'd like to add a note about that subject line.
Some years ago, a group invited me to talk to young writers in Illinois. I waited and waited for the final bit of information that I needed before I could purchase my airline ticket. Finally, I emailed them back, repeating my request. They insisted they had sent it -- with the subject heading of YOU. At that time my email system only showed the subject line and did not add the first sentence. It looked like SPAM, so I had deleted it without reading it.
Use that Subject Line to let the person know what is in the email. You want them to read your email, not delete it without reading.
