In charitable organizations, few assets are as valuable—and as underutilized—as the organization’s donor data. Many nonprofits focus primarily on campaigns, messaging and outreach strategies, and the data used to inform those efforts is often limited to insights on high-capacity donors, rather than a comprehensive view of the full donor base. Campaigns, messaging and outreach strategies are developed based on the opinions of a capital campaign consultant or the organization’s staff and board members.

Complete, current and accurate donor demographic and giving data isn’t just about keeping records organized. It’s about understanding your donors, building meaningful relationships and ultimately unlocking gifts over the long term. With an ongoing generational fundraising program based on three-, five- and seven-year time horizons, donor data becomes more than names and addresses. It becomes a strategic tool for growth and adjustments as your donors transition through their generational lifecycle.

The three pillars of effective donor data

At its core, a high-functioning donor database must meet three essential demographic and financial criteria: it must be complete, correct and current.

• Complete data ensures you have all the necessary information to identify and understand your donors. For your donor names, you should have their legal first, middle and last name and suffix and the postal-service-based address of the household. That should be supplemented with age, marital status and gender for complete demographic data. The file must have financial insights such as income, net worth and even the value of the primary residence
• Correct data guarantees that the information you’re using is accurate. When was the last time it was updated for donors who move, marry, divorce or pass away? Suffer financial losses or enjoy capital gains? A data update refreshes existing information, such as fixing an incorrect mailing address.
• Current data ensures that your insights reflect donors’ present circumstances, not outdated assumptions. A data append adds entirely new information to a donor record, such as identifying whether a donor has passed away or adding financial indicators.

Without these three essential pillars, even the most comprehensive fundraising communication plan can fail.

• Ongoing updates. Your data should then be updated annually to identify donors who are deceased. Organizations often find that 2.5% to 3.5% of the donors in their files may pass away each year, especially if their base skews older. Removing those records from active mailings can result in immediate postage cost savings.
• Demographic and financial data should be updated every 30 months to fully integrate with a three-, five- and seven-year planned giving strategy.
• Maintaining giving history records of deceased donors who included you in their estate plan is very important. Keep this information on a separate data storage device.

Sharpe Group’s tool to help your data become actionable

Since 1986, Sharpe has offered a donor data update and append tool initially using date-of-birth sources. That tool was enhanced in the early 2000s to include gender, marital status, estimated income and estimated net worth.

We have further expanded Sharpe Data to separate the value of the donor’s primary residence from their estimated net worth. This year, we are bundling a donor deceased flag into the update and append tool to provide a donor file that is complete, correct and current.

Fast and secure

To begin the data update, you submit your Excel or CSV file through a secure portal. We’ve seen our donor name match in the range of 95% to 100% depending on the completeness and correctness of the donors’ names. (This bundled update and append is only ~ 20 cents per name.) Your complete, correct and current donor data is returned to you within two business days. You will receive the formal report within a week.

With this information, you will now know more about your donor segments and how to set strategies and tactics. These details allow you to move beyond generic outreach and toward personalized engagement. Rather than relying on a “propensity score,” planned giving officers will know more about donors who may have included you in their estate plans.
