How to get a SharePoint person field's email adress

This week I had the need to access the email address of a user that was in a person field of a SharePoint list.

Well I incorrectly assumed that this was some flavor of  a SPUser object, turns out the person field in a SPList is a special type SPFieldUser.

Well lets cut to the chase this is the code to access the email address of a SPListItem person column;

private bool EmailUser(SPListItem spListItem, string recordColumn, string subject, string message)
        {
            SPFieldUser spFieldUser = (SPFieldUser)spListItem.Fields[recordColumn];
            SPFieldUserValue spFieldUserValue = (SPFieldUserValue)spFieldUser.GetFieldValue(
                                                    spListItem[recordColumn].ToString());
            if (string.IsNullOrEmpty(spFieldUserValue.User.Email) == false)
                return SPUtility.SendEmail(spListItem.Web, false, false, spFieldUserValue.User.Email, subject, message);
            else
                LogWrite("Error", string.Format("Send Email Error Message")
                                                ,spFieldUserValue.User.Name));
            return false;
        }
