The RMail and RSign feedback has been great. Everyone wants to use these products. The senior-level attorneys are always going to use RPost if they send anything out…The fact that RMail is going to be integrated with cleanDocs is going to encourage more use.

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 the effective audit 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.
