One of the purposes of referencing is to enable others to find the information that you have used in your work. As it is not possible for others to locate this source of information, you would not need to cite and reference it in the usual way. Instead you would include the email/letter/correspondence/communication in an appendix and refer to the appendix in the main body of your work e.g. (See Appendix 1).
