Spammers use pretty much the same protocols and mechanisms to send their mail as do you or I. However, the difference is that they use special tools and network resources (often hijacked or misused) to send out thousands or millions of copies of the same message in a single spam run. 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. Spammers know this, and they'll come back to take advantage of it. Often they'll link to a harmless looking site in their first comment (or include no link at all), but link to progressively more blatant spam in subsequent comments.

Spammers traditionally used 'open relays' to distribute their spam. Open relays allowed spammers to off load the job of sending thousands of emails to a powerful server with high bandwidth. Spammers can always emulate normal users (even to the point of building friendship networks) and then begin to follow people. Spammers also tweak the contents of their spams to defeat filtering techniques. Many spams contain "word salad" - for example, extracts culled from free online books - to disguise spam messages.

Spammers have now resorted to attaching PDFs to emails to entice users to open the PDFs and read their ads. Very annoying, since almost all spam including a PDF is much larger in size than a normal email. Spammers are now leveraging content from existing email and social networking scams to successfully launch similar attacks via new channels, including mobile. This prolific email message sent to mobile users prompted them to share personal information in order to find out who has a crush on them.

Unsolicited e-mails, however, are often the initial means for criminals, such as operators of fraudulent schemes, to contact and solicit prospective victims for money, or to commit identity theft by deceiving them into sharing bank and financial account information. Unsolicited commercial electronic messages must not be sent 17 . Commercial electronic messages must include accurate sender information 18 .
