Sign up with a free email account from Outlook or Hotmail ,Gmail and Yahoo Mail . The inbox shows a list of emails received, arranged in columns. The one towards the left shows who the email is from, the one in the centre gives the subject of each email, and you’ll find the time and date when each one was received in the right-hand column. If you haven’t opened and read an email, this information will appear as bold text in the list. Once you’ve opened and read the email and then returned to the inbox, the read email will be displayed in normal, non-bold text.
