PROOF & CMID
How the CaseMail ID Connects the Mailing Record
Documents uploaded to CaseMail or submitted through the CaseMail API are time-stamped and assigned a unique CaseMail ID (CMID).
The CMID connects the document to its mailing date, mailing history, tracking events, delivery-status information, and related Certificates of Mailing & Delivery. That connection helps preserve a clear record of what was mailed, when it was mailed, and the delivery history.
The CMID helps document three critical facts:
- What was mailed.
- When it was mailed.
- Tracking and delivery information.

Open each row to compare the traditional manual mailing process with the CaseMail approach.
01Labor, Operational Cost & SpeedManual preparation and post-office handling vs. online mail automation
Traditional Manual USPS Certified Mail
MULTIPLE MANUAL STEPSRequires printing, envelope preparation, completing postal forms, preparing mailing records, delivering or presenting the mailing to USPS, and organizing returned receipts and related records. These manual steps add staff time and administrative cost beyond postage and USPS service fees.
Automated CaseMail Platform
ONLINE PREPARATION & AUTOMATIONUpload documents, enter recipient information, select the mailing service, and submit the mailing online. CaseMail automates mailing preparation, production, tracking updates, and record organization, reducing manual handling and eliminating trips to the post office.
02Proof of Content AuthenticitySeparate proof of what was mailed vs. a cryptographically bound mailing record
Traditional Manual USPS Certified Mail
SEPARATE PROOF OF CONTENTMailing and delivery receipts do not identify the exact document inside the envelope.
USPS mailing receipts, tracking records, and return receipts can document mailing and delivery events, but the sender must separately maintain the document copy and supporting mailing records needed to show what was placed in the envelope.
Automated CaseMail Platform
CRYPTOGRAPHICALLY BOUNDSHA-256 Hashing & CaseMail ID (CMID).
Every mailing document is assigned a unique CMID and cryptographically hashed before automated printing and insertion. The document is cryptographically bound to its USPS barcode, creating a tamper-evident record that preserves document integrity and verifies the exact document associated with the mailing.
03Court Notice Mailing & DocumentationManual notice preparation and recordkeeping vs. connected mailing documentation
Traditional Manual USPS Certified Mail
MANUAL NOTICE PREPARATION & RECORDKEEPINGCourt notices may require preparing documents, managing recipient information, completing postal mailing steps, tracking delivery, and maintaining mailing and delivery records separately. This can require significant manual coordination when notices are sent to multiple recipients.
Automated CaseMail Platform
ONLINE SENDING & CONNECTED NOTICE RECORDSUpload the court notice, enter recipient information, select the mailing service, and send through CaseMail. The notice, CMID, mailing history, tracking events, delivery-status information, and related Certificates of Mailing & Delivery remain connected to the CaseMail record for documentation and later verification.
Courts, statutes, rules, and agency requirements determine the required method and legal sufficiency of a notice. CaseMail documents the sending process and resulting mailing and delivery records.
04Address VerificationManual address entry vs. automated USPS address verification
Traditional Manual USPS Certified Mail
MANUAL ADDRESS ENTRYAddresses are entered and maintained manually. Outdated addresses, typographical errors, or recipient relocation can contribute to Returned to Sender (RTS) mail.
Automated CaseMail Platform
AUTOMATED ADDRESS VERIFICATIONAddresses are checked using USPS CASS and NCOA data before mailing to help identify address-formatting issues and known address changes that may affect delivery.
05USPS Return Receipt IntegrationPhysical return receipts vs. electronic delivery records
Traditional Manual USPS Certified Mail
PHYSICAL RETURN RECEIPT — PS FORM 3811A physical Return Receipt is attached to the mailpiece, signed at delivery, and returned to the sender through the mail. Because the receipt must travel back through the postal system, receiving and filing the physical card adds another manual step. USPS also provides a separate inquiry process when a paid Return Receipt is not received.
Automated CaseMail Platform
ELECTRONIC RETURN RECEIPT INTEGRATIONDirect programmatic integration with USPS Electronic Return Receipt (DMM § 503.6.2.1). USPS electronically captures the recipient’s signature and delivery information. CaseMail retrieves the Electronic Return Receipt and displays the delivery record within the platform, eliminating the need to wait for and manually file a physical return receipt.
USPS reference: Domestic Mail Manual 503 — Return Receipt.
06Evidence & Record AuthenticationAssembled receipts and records vs. a connected verifiable mailing record
Traditional Manual USPS Certified Mail
DOCUMENTATION MAY REQUIRE ASSEMBLYUSPS mailing receipts, tracking records, and return receipts can document mailing and delivery events. However, the sender may need to maintain and connect those records with a copy of the document that was mailed and other supporting documentation.
Automated CaseMail Platform
CONNECTED, VERIFIABLE MAILING RECORDCaseMail connects the document that was mailed with its CMID, mailing record, USPS tracking and delivery information, and related Certificates of Mailing & Delivery. This creates a more complete record for verification, evidentiary review, and presentation when documentation of the mailing is needed.
07Organized Records & RetrievalSeparate paper and digital files vs. connected CaseMail records
Traditional Manual USPS Certified Mail
SEPARATE PAPER & DIGITAL RECORDSMailing receipts, tracking records, return receipts, scanned documents, and internal notes may be maintained in separate physical or digital files, requiring staff to organize and reconnect the records later.
Automated CaseMail Platform
ORGANIZED RECORDS & RETRIEVALKeep the copy of the mailed document, mailing history, tracking events, delivery-status information, and related Certificates of Mailing & Delivery connected to the CaseMail record for organized retrieval and later verification. The CaseMail ID relationship helps keep the mailing record, document, delivery information, and certificate history connected rather than relying on separate files and records.
