Spam means sending massive amounts of electronic junk mail that people haven't asked for.
In legal terms it means to send 'unsolicited commercial email'
This term is used because the vast majority of spam is sent in order to try and persuade you to buy something.
Many ISP email packages offer 'spam filters' that try to prevent these emails getting through to your inbox, but it is a very difficult problem to separate spam from wanted emails. Your email service may have a 'Bulk' or 'Junk' box that contain the diverted spam. It is then up to you to have a look to see if there are some real emails accidentally caught by the filters.
To give you an idea of the problem, it is estimated that around 80%-90% of all emails on the internet is spam.
