According to American Community Survey data, approximately 13% of Americans – nearly 43 million – move to a new address every year. DP Address Updater, powered by TrueGivers, captures all address updates with a nightly data refresh, ensuring that DonorPerfect users have accurate and up-to-date information for direct mail appeals. This has the dual benefit of saving printing and postage costs by eliminating invalid addresses, and raising more money by making sure direct mail appeals reach as many interested donors and prospects as possible.

DP Address Updater can substantially reduce undeliverable and duplicate mail pieces by identifying and correcting address errors before they enter the mail stream. Your records are compared against the National Change of Address (NCOA) database to ensure you have the most current addresses, and updates include ZIP+4 certification according to USPS standards.

According to the USPS

  • In recent years, nearly seven billion pieces of mail were Undeliverable as Addressed (UAA), costing mailers $20 billion annually in printing and postage
  • 75% of undeliverable mail could be avoided by running NCOA updates prior to the mailing
  • Having the correct address ensures that your mailings reach all of your supporters, maximizing your fundraising success
  • If you’re not regularly updating your database, an estimated 10-20% of your mailing list is invalid. Between printing and postage, nonprofits typically spend between $0.50 and $3.00 per direct mail piece. If you sent an appeal to 5,000 addresses that cost $1.00 per piece, you could lose $1,000 in direct costs – not to mention the gifts left on the table from supporters who moved and didn’t get your letter
