Slang term used to refer to excessive UCE as defined above. The Problem UCE is an extremely inexpensive way for organizations to reach potential customers for services, products, or in the case of charities, a donation. UCE is considerably more friendly to the environment, because electrons are considerably easier to dispose than paper, and the electricity used to transmit UCE is less than the energy used to make, print, deliver, and cart away the paper equivalent. Part of the reason that UCE is so inexpensive to send is that the sender does not bear the total cost of the transmission. Any opt-out request sent directly to an organization is honored by that organization and all agents operating on behalf of that organization.
All messages contain the company name, address, and working electronic mail address.
Replies sent to the working electronic mail address requesting removal from the electronic mailing list will be honored. The short answer is that UCE in large volumes can disrupt Internet usage for everyone. Overloaded mail servers crash under the load. User's mailboxes filled to the point that the mail service provider is forced to refuse mail. In certain countries, large volumes of mail cost big bucks to the recepients because flat-rate service is not available everywhere.
