Certified Communications

What is CaseMail?

CaseMail is a certified communications platform that enables businesses, organizations, and individuals to send, track, and certify postal mail and email online. It brings together USPS postal services, Certified Email, and connected certificates and supporting records to make communications easier to manage, review, and verify.

CommunicationThe postal document or electronic correspondence being sent.
Events & StatusSending, tracking, delivery, or verification events associated with the communication.
Certificate / Archive RecordThe supporting record used to review and document the communication later.

How CaseMail Works

Send. Track. Certify.

01

Send

Upload documents or initiate a certified electronic communication from the appropriate CaseMail service.

02

Track

Track postal mailings with USPS tracking and delivery-status information, or follow email activity for Certified Email.

03

Certify

Keep certificates and supporting records that document the communication and the delivery or verification history CaseMail receives.

The Record Behind the Communication

Keep the evidence connected to what you sent.

CaseMail is designed around the record that remains after a communication is sent: the message or document, the mailing or delivery events, and the certificate or archive record used to review what happened later.

Accessible Certificates

Access postal and email certificates connected to their communication records, making them easier to find, review, and manage.

Digital Evidence Archive

Keep communication evidence organized for later reference rather than scattered across separate systems.

Tracking & Delivery Status

Review postal tracking or electronic activity alongside the record it relates to.

Certificates of Mailing & Delivery

Maintain supporting certificates for postal workflows where CaseMail provides those records.
