How can I make address labels for those parishioners who do not have emails?

To generate mailing labels for anyone who does not have an email address complete the search process ( Using Family and Member Search ) Once you have determined your family search criteria, for example, Active families scroll to Reports > Mailing Labels.  Choose your salutation type, select Exclude Families with Emails, and uncheck 1 label per family.  This will print labels for any family that you defined in your search criteria who do not have an email.
