The present disclosure relates to an apparatus for transmitting election campaign messages to display the number of an acquaintance of a recipient. When a request to transmit an election campaign message is received from an election candidate, an election campaign message is transmitted to the terminal of the voter linked to the election candidate. When the election campaign message is sent, the sender number of the message sent to each voter is set as the mobile phone number of the election campaigner linked to the corresponding voter as an acquaintance. Therefore, the recipient does not feel resistance in receiving the election campaign message.
