In simplified style letters, what replaces the salutation?

In simplified style letters, the salutation is replaced by a subject line presented in uppercase letters. This is a key characteristic of the simplified letter style, which aims for clarity and efficiency in business communication. The use of a subject line helps to immediately inform the reader about the purpose of the letter, allowing them to quickly grasp the main topic without the need for formalities like "Dear [Recipient's Name]".

This replacement aligns with the overall goal of simplified style letters, which is to convey information in a straightforward and effective manner. The emphasis on the subject helps streamline communication, particularly in formal correspondence. Therefore, utilizing an uppercase subject line fulfills the criteria of this communication style effectively.
