Address File Audit · One file, one invoice
Your mailing file,
audited like it matters.
Upload the file you already mail to. You get it back standardized, deduplicated, geocoded and income-enriched — plus a written Address Quality Report you can put in front of a board: what's wrong, where it clusters, and what it costs you every year.
- The report is the product: standardization quality, ZIP completeness, duplicate clusters, county concentration, neighborhood income & vacancy profile, and a cost-of-bad-records model with stated assumptions. See a sample →
- The anchor: traditional list bureaus charge $75 per 1,000 records — $1,875 on a 25,000-row file — and hand back no analysis. This is $497 with the analysis.
- Built for donor files, member registries, government address lists, and ops teams who would rather upload a file than write an integration.
- One rule from the USPS Addresses license, stated plainly: the addresses must already be yours. We audit lists you possess; we never source, append, or build lists.
- Signed, expiring download links. Your file is never used for anything else and is deleted after 30 days.

01What the report answers
Eight questions, answered with your data.
How clean is it, really?
Standardization match rate against the Census Bureau's national address inventory — exact, corrected, and the rows that could not be standardized at all.
Where does it cluster?
Duplicate clusters on the standardized form, plus county-level geographic concentration — with counties named, not just coded.
Who are you mailing?
Neighborhood income percentiles and bands, and vacancy exposure — the tract-level profile you'd otherwise buy as a separate data append.
What does it cost you?
An annual-waste model over your at-risk and duplicate rows, with every assumption stated — postage, materials, cadence — so you can re-run it with your numbers.
