Main Benefit

Assurance and proof for intragovernmental communications and bid dispute resolution process communications.

The Government Accountability Office (GAO), an independent and non-partisan government agency that is part of the United States Congress, uses RMail and its Registered Email™ service for evidence of delivery of intragovernmental communications that are critical, as well as for assurance of time-dependent communications related to dispute resolution processes.


Senders have the RMail for Outlook app installed, and when using the Registered Email™ service, the sender receives an automatic analysis of the delivery forensics, cryptographically sealed to the delivery content and timestamp, and packaged as a Registered Receipt™ proof record.

The United States Government Accountability Office is effectively the audit branch of the US Federal Government. We’ve been providing them visibility of e-delivery of important communications to other parts of Congress, Federal Government departments, and to government suppliers along with the auditable proof returned via the Registered Email™ service.
