Sähköpostiviestit

Sähköpostiviestit, commonly known as emails, are a fundamental method of digital communication. They function by transmitting messages electronically between two or more individuals or groups through a computer network, most notably the internet. A typical email consists of several components: a sender's address, a recipient's address (or multiple addresses), a subject line that briefly summarizes the content, and the message body itself. Attachments, such as documents or images, can also be included.

The underlying technology for sending and receiving emails relies on protocols like Simple Mail Transfer Protocol (SMTP) for sending and Post Office Protocol (POP) or Internet Message Access Protocol (IMAP) for retrieval. Email services are provided by various entities, including dedicated email providers like Gmail, Outlook.com, and Yahoo Mail, as well as internet service providers. Businesses also utilize email extensively for internal and external communication.

While email offers speed and convenience, it is also susceptible to issues such as spam, phishing attempts, and security breaches. Proper email etiquette, including clear subject lines, concise messages, and appropriate tone, is important for effective communication. The widespread adoption of email has revolutionized how people interact, conduct business, and share information globally.
