Communication originating from outside a specific organization’s internal network domain is classified as external electronic mail. This signifies correspondence sent from an email address that does not belong to the company or entity in question. For example, an email sent from a Gmail or Yahoo account to a corporate email address is considered external.
The ability to interact with individuals and entities outside the organization is crucial for various operational aspects. It facilitates client communication, marketing initiatives, vendor relations, and information exchange with the broader community. Historically, it has replaced physical mail for many business functions, providing faster and more cost-effective methods of communication.
