RMail for Outlook Office 365 for Mac

Track email opens, prove email delivery, encrypt private email, and get documents signed electronically — all from within Microsoft Outlook Office 365 for Mac.

For every RMail message sent, the sender is returned legal and court admissible open tracking, proof of email delivery, proof of privacy compliance, and audit-trail records for recipient e-signatures on documents.

Main Services:

  • Track & Prove: Sends a Registered Email™ message. A Registered Receipt™ email record is then returned to the sender with court-admissible time-stamped proof of the content delivered and advanced open tracking.
  • Encrypt: Delivers files and email message body text and attachments encrypted direct to the recipient’s inbox with no need for recipients to register or click links, returning auditable proof of compliance and privacy.
  • E-Sign: Attach a document and send as Registered Email messages, formatted so the recipient can use their mouse to electronically draw or type their signature on the document, returning a legally signed contract to both sender and recipient

RMail is powered by RPost’s Registered Email™ technology, the global standard for email delivery proof.
