Maria Sainz:Jamie,Yes, only Constituent Queries can be used in the Appeal Mailings. But you can reference a Member or Program queries using the Selections tab in the Query Builder, as long as those other queries were saved as a dynamic selection and the checkbox "Show this Selection in the Query Designer" box is checked.It then has that Member/program query in the Includes records where: and you can either include or exclude those who are in that Query. It is a second query without needing to completely rebuild the original.
