“Inactive” is a status that YOUR organization determines. Bloomerang recommends that you use it aggressively -- to mark the records of donors who have not given in a few years or that you no long want to spend your resources cultivating. Inactive maintains all information on a donor but excludes them from costly mass-mailings by way of an exclude filter in reports, emails, and letters. To mark a constituent inactive, open their record, click on the “profile” tab, click the “edit” button in the upper right, and use the pull-down arrow on the “Status” field (first field in the Personal Information section) to select Inactive. Then click Save. Use the same steps to reverse the process.
