USPS volume has a flavor all its own: lots of packages, small margins, long tails of "where's my thing?" customer emails. If you sell on eBay, Etsy, Poshmark, Mercari, or run a small Shopify store, USPS is probably 60–80% of your shipments — and the tracking experience at usps.com has not meaningfully improved in a decade.

Google Sheets + one formula fixes it. This guide is the practical version — how to set it up, which USPS products it handles (Priority, First-Class, Media, Certified, Registered, international), and the quirks that come with USPS's own tracking inconsistencies.
