Certified Mail

Online Secure Document Delivery & Notarization

ZSentry Certified Mail provides full support for secure delivery and online notarization of documents. All ZSentry timestamps are referenced to the US NIST atomic clock time.

Server Send Receipt: Issued by the server and stored in the Outbox Report after the message is sent, giving you the ability to verify document sending, integrity, and delivery, for each ZSentry Mail sent during the session. A copy of the Server Send Receipt is also included in your Bcc secure archive copy (if both are selected in the Personalize Panel). You can also save the Outbox Report, with all Server Send Receipts, to a local file, print, or send by ZSentry Mail before you close the session.

Return Receipt: (if selected in the Personalize Panel) When the recipient opens your message, a Return Receipt is sent back to you with information on When, Where, How, and by Whom your message was read. You can compare the Return Receipt with the corresponding Send Receipt.

Message ID (Fingerprint): (if selected in the Personalize Panel) You and the recipient can match the Fingerprint listed in the message received and in the Return Receipt with the Fingerprint listed in the Send Receipt, providing evidence that the message was received as sent (Online Notarization).

Regulatory Compliance: ZSentry satisfies international, US federal, and state requirements for digital signature of documents and secure document delivery, including the Health Insurance Portability and Accountability Act (HIPAA), Federal Financial Institutions Examination Council (FFIEC), International Standards Organization (ISO) 17799, Gramm-Leach Bliley Act (GLBA), Sarbanes-Oxley Act (SOA), and U.S. State Security Breach Notification Laws. Evidentiary laws may vary by jurisdiction.

You can use ZSentry Mail (Zmail) for delivering secure documents online to anyone, without previous contact. With ZSentry Mail, the document is sent encrypted to the recipient's email address and digitally signed, so that only the recipient can read it. The recipient also knows that the document was delivered to exactly as you sent it, with a message ID (Fingerprint) providing Online Notarization. You can also verify the delivery time and place, if you need to, with a third-party verified US NIST timestamp.

All ZSentry messages, including headers and attachments, are copyright-, access- and copy-protected under the US Digital Millennium Copyright Act as well as other US and international laws. By using ZSentry Mail, the sender limits the right to read the message to its expiration time and original recipient(s).
