The Economics of Spam     [Listing added: 25 October 2003]
The rising tide of unwanted email threatens to swamp our inboxes and drown out the messages we do want. But why? The "junk mail" that the postal service delivers is not increasing at the same alarming rate. Some mail delivered by the postal service might be annoying, but the unwanted email we refer to as spam is way beyond annoying. All spam is irrelevant and intrusive but an alarming amount is offensive, fraudulent and illegal. And that's not all: spam is a burden to the person who gets it and the network of entities that deliver it.

Spam: The Silent ROI Killer     [Listing added: 2 October 2003]
Nucleus Research analyze the impact of spam on employee productivity, interviewing employees and IT administrators to help them conduct their study. They carry out estimates for costs per employee when using a spam filter and when not. They find out that companywide spam filters only reduce the productivity loss from spam by 26%, due to other problems that arise out of the usage of the spam filters themselves. Nucleus also found that productivity and IT impact are not the only concerns of administrators in managing spam. Many companies worry that even with filters, unsolicited e-mail sent to employees may provoke legal action.

False Claims in Spam     [Listing added: 22 September 2003]
In this report, staff of the Federal Trade Commission’s ("FTC") Division of Marketing Practices describes the results of its review of approximately 1,000 pieces of unsolicited commercial email (UCE), commonly known as "spam."

Why Am I Getting All This Spam?     [Listing added: 22 September 2003]
In the summer of 2002, CDT embarked on a project to attempt to determine the source of spam. To do so, we set up hundreds of different e-mail addresses, used them for a single purpose, and then waited six months to see what kind of mail those addresses were receiving. It should come as no surprise to most e-mail users that many of the addresses CDT created for this study attracted spam, but it is very interesting to see the different ways that e-mail addresses attracted spam -- and the different volumes -- depending on where the e-mail addresses were used. The results offer Internet users insights about what online behavior results in the most spam. The results also debunk some of the myths about spam.
