4. Keep the mail short and simple to understand:

This is a much required quality for an effective Email. No one wants to spend more time on the history of the point you want to discuss. Instead of mentioning the history of the product you need to sell, just mail that this is what I am selling and this is how it can benefit you. And mention, for more information contact so and so at this number.

5. Reply on time:

If you want a quick response to your mails from others first make sure you reply them on time whenever they send you a mail. Check your inbox frequently so that you don’t miss out any important mails.
