Email Notifications per Customer

Just as the banking and other industries, there is a Know Your Customer scenario here where we should be able to disable certain notification based on the customer. It makes sense to have all notifications going out to online customers, but those who have bulk orders often are being inundated by emails. I should be able to turn off all for a customer and only send email notification when I want. Possible solutions: 1)Turn off all and have a prompt when you click produced, shipped, etc. to send an email notification. 2)Or enroll email notifications when customers are being added as to which notifications they want.
