The company that put the certified letter on a blockchain - and made proof of delivery admissible in court.
Everyone has mailed something important and simply hoped it arrived. DPS built a business on a sharper question: what if you could prove it?
DPS - the Digital Postal Service - is a SaaS company that modernizes certified communications using artificial intelligence, blockchain, and Web3. Its flagship platform, CaseMail, lets businesses send, track, and certify both email and postal mail, wrapping every document in a cryptographic hash and a unique CaseMail ID. The result is a tamper-evident record of what was sent, when, and to whom.
That record is not a novelty. More than three million CaseMail certificates have been issued, and the company says they have been presented, unchallenged, in courts across every U.S. jurisdiction. CaseMail is an approved U.S. Courts notice provider and a USPS postal provider - a rare pairing of Web3 technology and century-old public infrastructure.
The company traces its roots to 2014, when founder and CEO Joe L. Ruiz set out to make certified mail digital without sacrificing its legal weight. Operating under VerTrius Corp and based in Santa Cruz, California, DPS spent a decade doing the unglamorous work of certified notice delivery before AI made the category a headline.
In April 2021, that patience paid off in a first: the U.S. Postal Service certified CaseMail as the first producer of blockchain-generated ePostage labels, built on NFT technology. Today the platform reaches enterprise users through the Microsoft Azure Marketplace and AppSource - court-ready proof, one click away.
"We've spent the last decade helping businesses ensure the integrity of their certified communications, whether through the mail or online."
Law firms, corporate legal departments, and government agencies that must prove a legal notice was delivered - plus enterprises and consumers reaching CaseMail through Microsoft's channels.
Traditional mail leaves gaps: lost green cards, disputed timestamps, unverifiable email threads. In a courtroom, hoping is not proof. DPS replaces the guesswork with a cryptographic receipt.
Every mailing is hashed and stamped on a blockchain, and CaseMail auto-generates USPS Certified Mail Electronic Return Receipts - a verifiable chain of custody designed to survive cross-examination.
Certified-communication tools are not new. DPS's difference is provability - and the reach to use it everywhere.
Figures per DPS public statements. Cost reduction is a company-reported estimate for automated vs. manual certified mailings.
"Using NFTs to help protect a process that's both familiar and important to everyone - mailing a letter or package - helps demystify this important new technology."
B2B and B2C subscriptions for certified email and mail, per-certificate and ePostage transaction fees, and distribution through Microsoft's marketplace. Reportedly bootstrapped, with a third-party ARR estimate near $13M.
DPS sits at the crossroads of legal tech, e-signature/proof platforms, and Web3 - competing with the likes of RPost and DocuSign, and with the humble USPS green card it aims to replace.
Ten-plus years spent satisfying the strictest audience there is - the courtroom - has shaped a product where every hash, timestamp, and receipt exists to hold up under scrutiny.
