How to Use Zextras Suite for Educational Mail Systems like SAT Test prep and Military Portals like Join Pak Navy?

We’re evaluating Zextras Suite to manage secure communication systems for two distinct purposes:

1. An educational testing environment like SAT Test prep, where students and instructors exchange messages, schedules, and test updates.

2. A secure portal similar to Join Pak Navy, where candidate data, correspondence, and internal workflows must remain confidential and highly available.

I’d appreciate insights on:

• Best practices for multi-domain email setup within Zextras for institutions.

• Secure collaboration tools and access control suitable for academic and defense workflows.

•
