The Power of Proof

When deadlines need to be met or when disputes may arise concerning “who said what when,” or “who received what when,” proof matters. With RMail’s Registered Receipt email record, you’ll get certified evidence of compliance with every RMail message you send, proving delivery, time of delivery, and exact message content. The Registered Receipt™ record provides court-admissible evidence of delivery and is considered an acceptable form of notice as defined by regulators.

Main Features for Government Treasury and Tax Professionals

Registered Email™ certified e-delivery tracking and proof provides advanced open and delivery tracking and proof, with timestamped proof of original content legally delivered. It returns to the sender a court-admissible timestamped Registered Receipt email without requiring any action or setting at the recipient level.

Registered Email proof is most popular among litigation support, lawyer, and other government professionals.

Email encryption automatically delivers email in a unique way to each recipient, creating the simplest user experience for the recipient while also returning auditable proof of privacy and compliance to the sender — going far beyond basic TLS and link-retrieval systems. RMail includes different levels of encryption for when it is important to keep messages private from recipient’s email administrators and others inside their organization.
