What is spam, where does it come from, and why do I receive it?

Spam email is a form of commercial advertising which is economically viable because email is a very cost-effective medium for the sender. If just a fraction of the recipients of a spam message purchase the advertised product, the spammers are making money and the spam problem is perpetuated.

Spammers harvest recipient addresses from publicly accessible sources, use programs to collect addresses on the web, and simply use dictionaries to make automated guesses at common usernames at a given domain.

Spamming is politically debated in several countries, and has been legislated some places with varying results. Spammers often conceal or forge the origin of their messages to circumvent laws, service provider regulations, and anti-spammer lists used by anti-spam software.

At the present more than 95% of email messages sent worldwide is believed to be spam, making spam fighting tools increasingly important to all users of email.

Spamming is the use of electronic messaging systems to send unsolicited bulk messages (spam), especially advertising, indiscriminately. While the most widely recognized form of spam is e-mail spam, the term is applied to similar abuses in other media: instant messaging spam, Usenet newsgroup spam, Web search engine spam, spam in blogs, wiki spam, online classified ads spam, mobile phone messaging spam, Internet forum spam, junk fax transmissions, social networking spam, social spam, television advertising and file sharing spam. It is named for Spam, a luncheon meat, by way of a Monty Python sketch in which Spam is included in almost every dish.

Spamming remains economically viable because advertisers have no operating costs beyond the management of their mailing lists, and it is difficult to hold senders accountable for their mass mailings. Because the barrier to entry is so low, spammers are numerous, and the volume of unsolicited mail has become very high. In the year 2011, the estimated figure for spam messages is around seven trillion. The costs, such as lost productivity and fraud, are borne by the public and by Internet service providers, which have been forced to add extra capacity to cope with the deluge. Spamming has been the subject of legislation in many jurisdictions.

A person who creates electronic spam is called a spammer.
