Model Behavior
Asking the right questions and mining your data accordingly can produce a picture-perfect
June 2009 By Tiffany Neill And Lynn MehaffyModeling is best used when you have a specific question that you’re trying to answer, such as: “Who are my best donors to approach for an upgrade?” “Which petition signers in my database have the best potential for contributing?”
If you do not have a specific question in mind, it still can be useful to see if there are characteristics influencing the outcome of a mailing that were not in your selection criteria. For example, if donors were selected for a mailing based on recency, frequency and gift size, you might want to look at the results by region, the acquisition package through which donors were acquired or by cumulative donor value over their lifetimes.
Before going into specific cases where modeling can benefit your program, it is important to remember that there are things modeling will not do:
- Modeling does not mean you can ignore direct-response best practices. For example, if you are modeling to eliminate donors from a mailing, test a sample of people you would have included had the model not eliminated them.
- Modeling does not make up for a weak case for support. When times are tough, your case for support must be stronger as you are competing with many groups for limited dollars.
- Modeling cannot capture the emotional element that leads to a contribution. The model can tell you who is more likely to give, but you still need to make a connection between that donor and your cause to motivate him to give.
Case No. 1: Can I save money on a premium mailing without harming results?
Many organizations send an annual premium mailing — calendars, cards or other front-end gifts — to donors. These mailings have become essential elements of many annual mail plans, raising hundreds of thousands of dollars for nonprofit organizations of every kind.
However, premium mailings are expensive. In an effort to cut costs, many organizations are looking for ways to reduce the quantity of these mailings without decreasing revenue. Looking beyond basic RFM segmentation helped one of our client organizations.


The Secrets of Direct Mail Testing
Greetings, I had a question about direct mail modeling. I would like some clarification or to learn more about direct mail modeling. Could you offer more resources to learn more about this?
Chances are I will have to do this for our donor database, and want to really understand what this is about. It sounds similar to segmenting, but with more information acquired through a type of screening, but I'm not 100% sure.
Thank you for your help!
