Email, or electronic mail, is a digital method of sending messages and files over the internet. It allows individuals and organizations to communicate quickly and efficiently by composing a message on their device, entering the recipient's address, and sending it instantly. The recipient can then read, reply, or forward the message from their own device. Think of it as an electronic version of traditional mail, but much faster and more convenient. Emails can include text, attachments like documents or images, and are fundamental for personal, business, and professional communication worldwide.
