Letter greetings are sometimes called salutations. Greetings in letters help to establish the type of letter a person is writing. Greetings are used in all types of letters from personal to business. Personal letters do not use the same type of formal greeting as a business letter would use. Examples of letter greetings for personal letters include a simple hi or hello and the person's first name. Examples of letter greetings for business letters would be a more formal 'Dear' followed by the person's first and last name.
