The Special Donor Export/Listing Report (located under Donor Reports was designed specifically for reporting and/or mailing to donors based on their prior giving history. 

The initial screen allows selection on gift dates and total amounts given between the selected dates.   It also allows you to exclude people if they've recently given.   After clicking OK, you can make further selection on Fund and other criteria.

After the report appears on the screen, you may elect to export data, which includes address & salutation, for mailing to the donors.

For more information on running this report, go to FIMS Help Online > Index> Donor Reports > Special Donor Export / Listing.
