Email
Email is mail sent electronically from one computer to another. Email messages can be sent to anyone with an email address, anywhere in the world. Email is stored on a computer and can be read when the recipient checks their email inbox—just like a post mailbox.
As well as text, emails can include attachments such as pictures, music and video clips.
While emails can be lengthy and formal, they are generally more casual in style than a written letter.
Users either need email software, such as Outlook, or a web-based email service such as Gmail or Hotmail to create and send email.
