Electronic mailing list subscribers are persons that get bulk email messages, such as weekly or monthly newsletters. Based on the mailing list client software that’s used to manage a particular list, they may have registered personally, giving their consent to be added to the mailing list, or they may have been added manually. The latter suggests that they will pratictically receive unsolicited messages. Typically, member list subscribers can be managed by the mailing list administrator who can add or remove them, or they can unsubscribe manually in case they do not wish to receive emails from now on. All subscribers will always get the very same content provided that they are part of one and the same mailing list, but a single member will never be able to view the rest of the mailing list members in the "To" field of the email.
