Email systems rely on specialized computer programs to manage the sending, receiving, and storage of electronic messages. These programs, running on dedicated hardware, ensure the reliable transfer of digital correspondence. For example, an organization might utilize a system designed to handle high volumes of internal and external communications, while an individual user may rely on a service provided by a third-party provider.
The architecture supporting electronic mail is fundamental to modern communication. Businesses depend on it for internal operations, customer relations, and marketing. Individuals use it for personal correspondence, staying connected with family and friends, and managing online accounts. The development of this architecture has significantly impacted how information is disseminated and consumed globally.
