Making your emails easy to respond to

One thing that a lot of salespeople do is to write long emails--in paragraphs.  And the customer has to ferret through the email to find out what the customer actually wants. 
Make your emails bullet points, or numbered.  That way the responder can respond to each item easily and can use your email as a todo list.
You need to appreciate the fact that people are getting dozens of emails a day.  If you want yours responded to, make it easy for the recipient to respond.
Short sentences; bullet points; easy to answer.  And to the point!
