Inactive is a constituent status your organization defines. You decide what it means and when to apply it. Common uses include constituents who haven't given in several years and constituents you aren't currently prioritizing for cultivation.
Marking a constituent inactive keeps all of their information. Nothing is removed from the record. You can then apply an exclude filter in reports, emails, and letters to leave inactive constituents out, so you can focus your mailing budget on the people you're actively engaging.
To mark a constituent Inactive, open their record and follow these steps:
Click the Profile tab.
In the Basic Info section, click the Edit.
From the Status list, select Inactive.
Click Save.
Use the same steps to reverse the process in the future if you determine the constituent should be considered active.
