An internet telephone coupon service method using an e-mail is provided to use a free internet telephone without visiting a web site by providing a free internet telephone coupon and simultaneously requesting to check an advertisement, thereby removing an unwelcome feeling for member subscription and an advertisement mail. If a receiver checks a mail, the receiver calculates a fact that the receiver checks a first advertisement included in the mail(S5). The receiver determines whether to use a free internet telephone coupon included in the mail(S6). If the receiver selects the internet telephone coupon(S7), a server transmits a program for using an internet telephone to a user terminal(S8). The receiver makes a call by using the free internet telephone by an interface(S9). |
