Most businesspeople have pretty easy to see incentives. At the end of the day, they want to grow their business (whatever that means for their industry and specific role), hire great talent, and delegate urgent-but-not-important tasks to that talent. They also want to avoid losing money, adding unnecessary tasks to their to-do lists, and looking bad in front of stakeholders. Help them do the things they want and avoid the things they don’t want and you can get your foot in the door. And don’t make the email hard to read (i.e., long, prose-like text).
