ZTmail.AI will launch its global public beta on August 20
August 12, 2026

ZoTrus Technology today announced a complete revamp of its Email Security section at zotrus.com/email/, along with the launch of a new dedicated website for ZTmail at ztmail.ai. At the heart of this revamp, ZTmail will officially begin public beta on August 20, coinciding with the company's 5th anniversary and a limited-time 80% off promotion.

1. Why the Revamp: From "Browser-Integrated" to "Standalone Product"

Three years ago, ZoTrus Technology began planning an automated email encryption service, initially designed as an integrated email client within the ZT Browser. The goal was to let users "enjoy the convenience of webmail while sending encrypted emails as effortlessly as plain-text emails."

However, as development progressed, the team identified two fundamental issues by embedding the email client as a browser feature:

  • Browser interaction models are ill-suited for email processing.
    Email handling demands multi-account management, quick switching, sending and receiving, offline operations, certificate management, all functions that require deep customization for the email scenario, not as an "add-on" feature of a browser.
  • Users won't switch browsers just for an email feature.
    Browsers are among the most frequently used tools daily, and users have their own preferences. Asking them to switch browsers solely for encrypted email carries too high a decision cost.

Based on these considerations, ZoTrus Technology made a strategic decision: spin off the email client from the ZT Browser and build it as an independent, focused product.

2. What Changed: From "3-in-1" to "Standalone + AI-Powered"

Originally, the ZT Browser integrated an email client and a PDF reader into a "3-in-1" product. Following this revamp, the email client emerges as a standalone product under the new identity of "ZTmail", with three major upgrades:

  • Standalone Product. ZTmail is no longer tied to the ZT Browser. It is an independent desktop email client supporting Windows, macOS, and Linux, with iOS and Android versions planned.
  • AI-Powered. ZTmail integrates a bring-your-own-AI capability. Users can freely choose their preferred AI models, bring their own API keys, and leverage smart features such as email drafting, polishing, translation, summarization, and schedule extraction. The AI assistant is fully controlled by the user.
  • Core Automated Encryption Unchanged. ZTmail retains the core technical advantages of the original solution: based on S/MIME international standards and China cryptographic standards (GM/T), supporting dual RSA and SM2 algorithms, with automated certificate provisioning for end-to-end encryption and digital signatures.

3. Public Beta on August 20 with 5th Anniversary 80% Off

ZTmail public beta will officially launch on August 20, 2026, coinciding with ZoTrus Technology's 5th anniversary. The public beta will offer full core functionality, allowing users to experience automated email encryption for free.

To celebrate the company's 5th anniversary, the charged service - Trusted Identity Edition will be available at an 80% discount from August 20 to August 31:

  • Individual Identity Edition (T2·Individual-Validated): 48 RMB/year → 10 RMB/year
