An electronic mailing list or email list is a special use of email that allows for widespread distribution of information to many Internet users. It is similar to a traditional mailing list – a list of names and addresses – as might be kept by an organization for sending publications to its members or customers, but typically refers to four things:a list of email addresses, the people ("subscribers") receiving mail at those addresses, the publications sent to those addresses, and a reflector, which is a single email address that, when designated as the recipient of a message, will send a copy of that message to all of the subscribers.
