If all (or some) of your addressees are BCC (blind carbon copy) there will be no TO header and email applications will use the undisclosed recipients phrase.
BTW this is proper email etiquette if all recipients should get the message, but don't need to know each others' email addresses. Mailing lists are a good example of this.
