PURPOSE: A method and system for supplying information data using an E-mail is provided to enable a user to receive various information without a load of information rental fee by checking an advertisement included in an E-mail, thereby receiving information without pay. CONSTITUTION: A mail server transmits E-mail including an advertisement icon, a summary to information data, and a method for receiving the information data without pay to a plurality of users(S301). If a user clicks the advertisement icon, a free supply requesting message to the information data is generated. If the user clicks a selection icon, a charged information data supply requesting message is generated. A web server checks whether a free requesting message to the information data is received from a user computer(S303). An information managing server displays an advertisement being linked to the advertisement icon being stored in an advertisement database on the user computer(S305). The web server updates an account information database by subtracting an advertisement charge from an account of an advertiser(S307). The web server makes an E-mail including the information data be transmitted to the user computer. The web server displays the information data(S313) and performs a log-out process(S315).
