TeraMail for Business

Secure messaging and file delivery between authorized users.

Browser-based access from Edge, Chrome, Firefox, Safari, and other modern browsers.

Instant two-way communication between desktop users and TeraMessage Mobile users.

Exchange sensitive documents, images, and files without relying on public email systems.

Delivery confirmation, read receipts, and communication audit logs.

Private enterprise communications under your organization's control.

Create Your Company's Private Communication Environment.

TeraMail gives your organization its own private, controlled environment for communicating with employees, clients, contractors, consultants, suppliers, and business partners.

Your organization determines who is authorized to participate and uses Groups to control who can communicate with whom.

Desktop and browser users communicate with TeraMail.

Smartphone users communicate with TeraMessage Mobile.

Together, they create a private business communication service for exchanging messages and files without relying on SMS, WhatsApp, or other consumer messaging applications.

Start with TeraMail — No TeraKey Required

TeraMail operates independently from TeraKey.

Authorized users access TeraMail through Edge, Chrome, Firefox, Safari, or other modern web browsers without installing software or browser extensions.

Your employees can communicate privately with each other, while selected people outside your organization can also be registered as authorized users.

For example, you can add a client, contractor, consultant, supplier, or business partner to your TeraCryption service, assign TeraMail access, and place that person in the appropriate Group.

The user receives credentials to access your private communication environment and can exchange messages and files with the people your organization has authorized.

Extend Private Communications to Mobile Users

TeraMessage Mobile extends the same private communication environment to authorized smartphone users.

TeraMail users working from computers can exchange messages with TeraMessage Mobile users working from smartphones, allowing office personnel, remote employees, field personnel, managers, and other authorized users to remain connected within the organization's controlled communication environment.

Add TeraKey When Files Need Protection at Rest

TeraKey is not required to use TeraMail.

When your organization also needs files to remain encrypted after they are delivered and stored on authorized computers, TeraKey can be added to extend protection from private communications to persistent file-level encryption.

Organizations using TeraKey can also exchange TeraKey-protected files through TeraMail and use TeraCryption's secure file-sharing workflows.

Start with private communications. Add persistent file protection when your organization needs it.

How TeraMail Works

Your Organization Controls Who Can Participate

Your TeraCryption administrator creates and manages the users and Groups that make up your private communication environment.

Employees can be organized into Groups according to departments, projects, responsibilities, or other business requirements. Selected clients, contractors, consultants, suppliers, and business partners can also be added and assigned only to the Groups in which they are authorized to participate.

This gives your organization control over who enters the communication environment and who can communicate with whom.

Adding an Employee, Client, or Business Partner

To add a new TeraMail user, the administrator creates the user's account, enters the required contact information, assigns TeraMail access, and places the user in the appropriate Group.

The system sends the new user an email containing a username and temporary password.

There is no TeraKey installation required. The user simply opens the TeraCryption service in a modern web browser and signs in.

During initial registration, the user is required to create a new private password. On the subsequent login, an SMS verification code is sent to the user's registered mobile phone for identity verification.

The user is now authorized to participate in your organization's private communication environment according to the Groups and permissions you have assigned.

Sending a Private Message and File

An authorized TeraMail user can compose a private message and attach one or more files.

The message and files are transmitted to the TeraCryption service through a TLS 1.3 protected connection. Upon arrival, the message and attached files are encrypted and stored separately by the TeraCryption service pending delivery to the authorized recipient.

The confidential message and files are not sent through public email.

Immediate New Message Notification

When a new TeraMail arrives, PageRouter provides immediate notification to the recipient.

If the recipient is currently using TeraMail, an audible alert and flashing notification announce the pending message.

If the recipient is not logged in, TeraCryption sends a standard email notification informing the recipient that a confidential message is waiting. The confidential message itself is not included in the notification email.

The recipient signs into TeraMail to retrieve it.

Automatic Logout and Continuous Operation

TeraMail can accommodate both individual users and continuously staffed workstations.

For each user, the administrator can enable automatic logout after 20 minutes without mouse activity. This helps protect unattended TeraMail sessions when users leave their computers.

For users who need TeraMail continuously available—such as supervisors, dispatch personnel, reception desks, or other continuously staffed positions—the administrator can allow TeraMail to remain logged in while the workstation is operating.

If the Internet connection is interrupted, TeraMail automatically logs out the user, requiring authentication when reconnecting to the service.

Know When Your Message Has Been Read

When the recipient opens the TeraMail notification, the sender receives confirmation that the message has been read.

This provides business users with immediate message status instead of wondering whether an important communication was received or opened.

Secure File Delivery

Files attached to a TeraMail are stored separately from the message and remain protected while awaiting delivery.

When the authorized recipient selects the file link, the file is retrieved and delivered through the protected TeraMail connection. The recipient can then download the file to the computer.

When TeraMail is being used without TeraKey, the downloaded file is not protected at rest by TeraKey.

If your organization requires the file to remain encrypted after delivery, TeraKey can be added to provide persistent file-level protection on authorized computers.

TeraMail protects the private communication and delivery process. TeraKey can be added when the file itself must remain protected after delivery.
