Circulars are official communications used by organizations, such as businesses or government agencies, to convey important information to a specific audience. They can include updates, announcements, policies, or instructions and are often distributed in printed or digital formats. Circulars help ensure that everyone receives the same information simultaneously, promoting clarity and consistency. Typically, circulars are structured with a clear heading, date, and body text that outlines the message. They may also include contact information for further inquiries. Organizations often use circulars to keep employees, stakeholders, or the public informed about changes or events related to their operations or services.
