How to Write Business Emails: 11 Steps (with Pictures) – wikiHow
The greeting should be concise and formal. You may or may not choose to address a person specifically by name, depending on the context of the message. A message to another business or to an unspecified person does not require a name.
An appropriate closing is polite and signals that the email has come to an end. While the closing of an email may not bear a common letter closing such as “Best Wishes” or “Sincerely,” it is considered a “best practice” to provide a closing to your email.
It is appropriate to write your name at the end of an email. Many email programs allow you to provide an automatic signature that is customized to your liking. Be sure that the formality of your response matches the details of the email. You may want to provide your full name and title in a work email to another business or to someone you have not met, while your first name alone may be appropriate in an email to a coworker you see every day.
