4. Standard Components for Letters
Block vs. Modified Block
Salutation
Complimentary Close
Mixed vs. Open Punctuation
Subject Line vs. Reference Line
While formats may vary from document to document and organization to organization, these components are standard for most business documents. Block format, which avoids tabs and lines up document sections on the left, is very popular in business. Salutations generally begin with Dear and typical complimentary closes are Sincerely and Cordially. Mixed punctuation uses a colon after the salutation and a comma after the complimentary close while open punctuation omits punctuation with these document elements. A subject line tells the reader what the message is about while a reference line refers to a number from a previous message or an order or invoice.
