Install an RMail App

• Sender Selects: sender clicks the RMail “Send Registered” button and selects send features.

• RMail Recommends: AI-infused prediction technology that, based on message criteria, automatically sensitizes senders, training them in-the-moment of sending, as to what RMail features should be applied to that message, and then sends with the recommended email protections.

Enable the RMail Gateway

• Secure Email Gateway: RMail Gateway is a suite of inbound email protections along with specialized outbound data leak and information protection services. Based on message metadata and administrator rules, RMail Gateway determines which messages should be sent with which added RMail features and automatically sends the message in that manner.

RMail is best for…

RMail’s transmission e-security services are used by businesses that send important, sensitive, or consumer-regulated information. These RMail services are generally applied to email in terms of (a) easier to use and more automated email encryption for privacy compliance, (b) assurance and peace of mind related to delivery and open status of important and time-bound email, (c) returning a verifiable proof record of who said what to whom by email, (d) need a timestamped proof of content delivered, (f) need to share large files securely, or (g) need to easily obtain a recipient e-signature on a sent document.

Product Description

Main RMail transmission-centric features:

• Registered Encryption email security automatically delivers email in a unique way creating the simplest user experience 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.

• Registered Email certified e-delivery tracking and proof provides email open/delivery tracking and evidence, with timestamped proof of original content legally delivered. It returns a court-accepted timestamped Registered Receipt email without requiring any recipient action.

• Secure Large File Share -- senders can easily attach and track up to 1GB of files from Outlook or the RMail Web app. Senders can send securely to any recipient with encryption and configurable self-purging options (from 1 to 90 days) in a one-time online storage box that eliminates the risk of download recipients being able to see sender’s cloud storage file structure.

• RMail E-Sign and RSign are the simplest, most affordable full featured web-based electronic signature services. RSign makes it easy for signers to complete and sign documents using any desktop or mobile web browser.

• Disappearing Ink and ViewProof -- senders can tag certain parts of an email message to disappear from within the email after delivery after a designated amount of time since sending, based on number of views, or time per view. Senders can receive verifiable proof that the recipient has viewed selected tagged parts of an email.

• Redact Reply – senders can redact particularly sensitive text in a sent message such that if the recipient replies, that sensitive text is automatically removed from the reply email thread.

• SideNote® service – makes it easy to append a private “sticky note” to a copied or blind copied recipient, so they have context as to why they were copied, and with Disappearing Ink enabled, that note can be set for one-time-view and to disappear from the recipient inbox after.
