slang that refers to unsolicited commercial email (UCE) or unsolicited bulk email (UBE).Some people refer to this kind of communication as junk email to equate it with the paper junk mail that comes through the US Mail.Unsolicited email most often contains advertisements for services or products, but very few reputable marketers use UCE to advertise.
One of the most common tricks is to relay messages through the email server of an innocent third party.
This tactic doubles the damages: both the receiving system and the innocent relay system are flooded with spam.
And for any mail that gets through, often the flood of complaints goes back to the innocent site that was made to look like the origin of the spam.
Back to top Unlike junk paper mail, email spam costs the sender very little to send; almost all of the costs are paid by the recipient and the carriers, because the spammer does not have to pay for all the Internet tied up in the delivery of the spam.
Because they have no incentive to be efficient in their mass emailing, spammers usually don't put much effort into verifying email addresses; they use automatic programs called bots to scour the web and , collecting addresses, or buy them in bulk from other companies.
Spammers also guess at addresses using name generation programs, and even send thousands of messages that bounce.
In order to get a single response, spammers are willing to send out a thousand email messages or ten thousand; it makes very little difference to them.
Many spam emailers use tricks to get you to read their messages.
For example, they use the "Subject:" line to entice you to open the message.
