You may want to identify donors that have given at some point in time, but have not given this year. These could be donors that gave ten years ago, but haven't made a donation since. It could possibly be donors that gave last year, and just haven't made a donation this year.
eTapestry has a standard query called SYBUNT to pull these accounts. SYBUNT stands for Some Year But Unfortunately Not This. The query will pull any account that has given a donation in their history, but has not yet donated the year you run the query. There also is a Some Fiscal Year But Unfortunately Not This (SFYBUNT) query if you organization is on a Fiscal Year.
Click Queries on the menu bar

Click Preview under the SYBUNT query
If you click the word SYBUNT you will open the query builder. Since this is a standard query you will not be able to make any edits to the query.
