circulars

Circulars are formal communications issued to a broad audience within an organization, government, or market to convey information, instructions, or notices. They are intended to be clear, concise, and widely disseminated, often using standardized language. Circulars may be official government notices, memos within a company, or promotional mailers sent to customers.

Types include official circulars, which originate from a central authority and target subordinate units to outline policies, procedures, or regulatory guidance; corporate circulars, which communicate internal changes such as policy updates, deadlines, or safety requirements; and advertising or promotional circulars, which are printed or digital leaflets distributed to the public or specific markets.

In government, circulars are commonly used to ensure uniform interpretation or implementation of policy across departments. In business, they serve to inform employees, coordinate actions, or announce opportunities such as calls for bids or meetings; in retail, advertising circulars advertise sales and promotions.

Distribution can be via email, intranet postings, or physical copies, and in many jurisdictions, requirements for publication or record-keeping apply. While useful for consistent communication, excessive or poorly targeted circulars can lead to information overload and reduced responsiveness.
