PostalProof keeps your mailing lists clean, compliant, and penalty-free with AI-powered address hygiene and Move Update monitoring.

Auto-corrected and ready for mailingEvery bulk mailer must comply with USPS Move Update rules, which require addresses to be refreshed every 95 days. Miss it, and USPS adds costly postage penalties to every piece of mail. Most small and mid-sized businesses, nonprofits, and in-house teams don't even realize how much money they're losing until it's too late.
USPS charges extra postage for every piece of mail with stale addresses. For a 10,000-piece campaign, that's $800 in penalties alone.
NCOA outputs are cryptic and confusing. Most SMBs struggle with technical codes and complex workflows that require specialized knowledge.
