Scheduled Sending Messaging and Files
TeraMail allows you to schedule messages and files for future delivery.
This is useful when communicating across time zones or sending sensitive reminders—such as invoices or payment notifications—that should not travel through public email channels. Simply compose the message, attach files, and schedule the date and time for secure transmission.
Secure Message Notifications
When a new secure message is sent to the recipient that is not logged in, TeraCryption sends a standard email notification alerting the recipient that a confidential message is waiting in TeraMail. The message content itself remains protected.
User-Friendly Experience
Despite its advanced security, TeraMail is easy to use.
• Clean, intuitive interface
• Simple message and file sharing
• Delivery and read receipts
• Visibility into user availability and message status
TeraMail and TeraKey
If you subscribed to TeraKey to encrypt files, the TeraMail browser appears within the TeraKey frame to allow users to communicate TeraKey-encrypted files attached to messages. In this case, only those with permission to use TeraMail and TeraKey can decrypt TeraKey-encrypted files received attached to TeraMail messages.
TeraMail and the TeraMessage Mobile app
Use TeraMail to exchange encrypted messages and files with TeraMessage Mobile users. For example, dispatch operators in a hospital communicate secure messages and files with medical personnel to comply with HIPAA. TeraMail and TeraMessage users can chat via instant messages or exchange documents and images over a data channel protected by TeraMail encryption.
