The Greeting of the email is where you address the person. Never start an email without a form of greeting!

In a formal message, you can use the recipient’s name or surname and title. Where in an informal greeting, you can use the name of the recipient. 

Suppose you have multiple stakeholders in an email. In that case, you can use the greeting to pinpoint whom you are focusing on and expecting a reply from.
