Simply put, spam is unsolicited e-mail. They are usually advertisements, but sometimes they are scams, attempting to entice a person to divulge personal information (such as bank account numbers).

Spam typically starts to show up when you register your e-mail address on a website or give it to a person with bad intentions. It is also possible that you end up on spammers' lists after after they generate mass searches.

Once your address is on a spammer's list, your e-mailbox will fall prey to spam--a few at first, then slowly ever more, until you or your mailbox is overwhelmed.

The main risk of not confronting a spam problem is the saturation of your e-mailbox. Another problem is the huge loss of time incurred by sorting out the legitimate messages hidden among the spam. The risks might seem small--or even inexistent--when your e-mail address has not yet made its way onto spammers' lists. But it will happen sooner or later to almost everyone, and the consequences are irreversible.
In the case of a company, the costs incurred by spamming are often high, in terms of lost bandwidth, hard drive storage, and above all else, in human resources.
