You know that there are strong reasons to send thank you letters to all donors, regardless of the size of the gifts. I want to give you some ways to help evaluate small gift donors, in order to see if you can increase giving rates and/or amounts.
1. Use Groupings to identify "small" gift donorsIt's true that some people will give multiple gifts, of varying amounts, and in order to insure that you are looking at "small" gift donors only, you'll need to create a grouping. You'll want to base the grouping on gift size, of course, but just how can you get those who have given ONLY small gifts? Well, first, when you start the grouping criteria, choose the Common Pattern of "All Donors" (date range optional). Then, to isolate it to just those who have only small gifts, click the "Finish Criteria" button, use the "AND" separator, and start a new criteria line. In this line, choose the Gifts tab, and select an "Amount Given" range (in Details tab) of a dollar more than your "small" gift limit (i.e., $21 if you consider $20 or less a small gift) through "blank", and select "Any Single Gift". This sounds counter-intuitive, since it's asking for anyone who has given a $21.00 or greater gift, but hold on. Click the "Finish Criteria" button again, and, this time, apply the "NOT" qualifier to the line. Now your criteria should read (more of less): select everyone who is a donor AND who has NOT given a gift of $21 or more. This eliminates both non-donors and those who have given gifts over $20. Now you can use this grouping with various reports.
