Why does clean fundraising data matter for nonprofits?

Your donor data is one of your most valuable fundraising assets. But when it’s disorganized or inaccurate, it can quietly chip away at campaign success, donor retention, and staff efficiency.

The good news? Most data mistakes are fixable—and preventable. Here are five of the most common data issues we see at Leadout Nonprofit Partners, plus simple steps you can take to correct them.

Mistake #1 – Duplicate donor records

Why it’s a problem: Duplicates lead to multiple emails, confusing acknowledgments, and reporting errors.

How to fix it:

• Run regular deduplication processes in your CRM
  
• Standardize naming conventions (especially for households and couples)
  
• Assign one team member to oversee data hygiene practices

Mistake #2 – Inconsistent data entry

Why it’s a problem: If addresses, gift types, or campaign codes are entered differently each time, it becomes hard to sort, segment, or report accurately.

How to fix it:

• Create a simple, documented data entry guide
  
• Use dropdowns or required fields in your CRM when possible
  
• Offer quarterly team refreshers on best practices

Mistake #3 – Unsegmented mailing lists

Why it’s a problem: Sending the same message to every donor misses the opportunity to personalize—and risks donor fatigue.

How to fix it:

• Segment lists by giving history, engagement level, or interest area
  
• Start small: try one segment for new donors, one for recurring donors
  
• Use segmentation to test and improve results over time

Mistake #4 – Missing or outdated contact info

Why it’s a problem: Without current emails or mailing addresses, you can’t reach your donors effectively.

How to fix it:

• Use NCOA or email verification tools annually
  
• Add update prompts to thank-you emails and receipts
  
• Train staff and volunteers to verify contact info during events or calls

Mistake #5 – Underused donor history

Why it’s a problem: If you’re not looking at donor behavior over time, you miss trends, upgrade opportunities, and warning signs of donor drop-off.

How to fix it:

• Create donor summary reports that include lifetime giving, recency, and frequency
  
• Review data quarterly with your fundraising team
  
• Use the info to inform ask amounts, stewardship timing, and thank-you strategies
