Data Quality Services for Nonprofits

For a nonprofit operating on a tight budget, what’s the real cost of sending fundraising appeals to outdated donor addresses?

It’s wasted postage. It’s wasted printing costs. It’s lost donations from supporters who never received your appeal because they moved two years ago. Every piece of undeliverable mail represents money that could have been spent on your mission instead of on the postal service.

How much of your fundraising budget is being wasted on bad data right now? If you’re like most nonprofits, you don’t have an exact number. But you know it’s significant. You’ve seen the returned mail. You’ve watched email campaigns bounce. You’ve heard volunteers complain about disconnected phone numbers during phone-a-thons.

Think about the impact on donor relationships. When a loyal supporter moves and updates their address with everyone except your organization, they stop receiving your appeals. They assume you’ve forgotten about them. How many lapsed donors in your database aren’t actually lapsed—they just never received your outreach?

And then there’s the efficiency problem. Your development team spends hours managing duplicate records, correcting inconsistent data entry, and trying to figure out which version of a donor’s information is current. What could your team accomplish if they spent that time cultivating relationships instead of cleaning data?

What We Deliver

Donor Address Verification with NCOA: We process your donor database through the National Change of Address system, updating addresses for donors who have moved and flagging undeliverable addresses. Your direct mail reaches the people who support your mission.

Email Verification for Donor Communications: We validate email addresses in your donor database, removing bounced addresses and typos. Your email appeals reach real inboxes, protecting your sender reputation and maximizing open rates.

Phone Number Validation: We verify phone numbers for phone-a-thons and donor outreach, identifying disconnected numbers and mobile versus landline. Your volunteers connect with real supporters instead of wasting time on dead lines.

De-Duplication and Merge: We identify and consolidate duplicate donor records, giving you a single, accurate view of each supporter’s giving history and contact preferences.

The Impact of Reaching Every Supporter

No more lost donations from supporters who moved. Just the satisfaction of knowing your message is landing with the people who care about your cause.

Your fundraising efficiency improves dramatically. More appeals delivered means more donations received. Better data means better donor segmentation, which means more relevant communications and higher response rates. What would a ten percent increase in fundraising revenue mean for your programs and services?
