What is another name for a written message used in business?

A written message used in business is often referred to as a memo, which is short for "memorandum." Memos are typically used to communicate important information, updates, or announcements within an organization. They are often concise and focused, conveying necessary details without the formality of a letter.

In the context of business communication, a memo serves a specific purpose and is a standard method for intra-company communication. It can include directives, advisories, or requests for action, ensuring that all team members are informed and aligned. While notes, letters, and announcements are also forms of written communication, they do not carry the same specific connotation or usage as memos do within a business setting.
