Question Hitendra from India asked, "What should I use for a greeting in a formal email, Hi + name, or Hello + name?"
Answer
Hi and Hello should not be used in formal email messages. In formal emails, it is best to begin with Dear + title (e.g., Mr., Ms., Professor, Dr.)+ last name + comma, as in the examples below:
Dear Ms. Johnson,
Dear Professor Kahn,
For less formal messages you can use the person’s first name, as in:
Dear Michael,
especially if the person you are writing has already written to you this way or has signed their first name in a message to you.
For informal and personal messages you can use either Hi + name or Hello + name, as shown below. Hi is more personal and less formal.
