Start your email by asking for what you want them to do or to know.
Most people lose interest after about 15 seconds, so I always start the email by saying exactly what I need the recipient to know/do and then include the details about why beginning as a separate paragraph so that if they bail after the first sentence or two at least i've gotten my key point across. If they want the details then they are there later in the email.
