DeliverySlip’s secure email messaging allows users to send out secure messages to any recipients, whether or not they are registered users. Guests can respond to messages sent to them, and initiate new messages with any users included in previous communications. Advanced message controls enable message encryption, freezing of forwards or replies, password protection of individual messages and attachments, viewing restrictions, and message expiration. Sent messages can be tracked in real time, with unique record IDs automatically created for each message and attachment. Users can also control sent messages, with tools to remediate user errors, such as recalling documents which should not have been sent.

With DeliverySlip, users can request document approvals and electronic signatures from within their inbox. Multiple signature types are supported, including typed, stamped, and wet signatures, biometric authentication, advanced PIN codes, and SSO re-authentication, to ensure that the identity of endorsers is verified. Document versioning and activity tracking enable the production of full chains of custody. DeliverySlip’s API also allows users to integrate secure approvals and electronic signature into existing digital workflows.
