A controller of a mobile communication apparatus, such as a cellular phone, that determines whether a received email is urgent by comparing words and phrases contained in the received email with keywords and phrases in a database. The controller generates notice information, such as an icon, when the received email is determined to be urgent, so that a user can recognize that there is an email whose sender wants to contact the user. When the notice information is selected by manipulating a key input device, the controller makes a communication with the sender of the received email.
