About 1 in 8 Americans moved in 2024.

That's roughly 39.6 million people (US Census Bureau, ACS 2024). If your donor file is a year old, a real share of it now points at someone else's mailbox.

  • Year-end appeals come back.USPS reports 3.64% of mail was undeliverable as addressed in FY2025, and older lists run worse than average. Every returned piece costs you printing, postage and a missed ask.
  • Receipts don't arrive.Donors need a written acknowledgment for any single gift of $250 or more (IRS Publication 1771). A receipt that bounces or comes back becomes a support call in February.
  • Email appeals hurt your sender reputation.Old addresses bounce, and a high bounce rate pushes your next campaign toward spam, right when giving peaks.

Bad donor data is a fundraising problem, not an IT problem.
