Secure Email Communication with TTB

TTB Secure Email

When you receive an encrypted email from TTB, you can rest assured that it has gone through a secure transmission process. To accomplish this, we use an encryption tool called Zix Portal. In order to read our encrypted email, you must first register your email address with Zix Portal. Once you are registered, you will speed up the process of opening any future encrypted email you may receive from us. You may also use this system to safely send encrypted email to us.

Please see How to Register Your Email with TTB-Zix for more information, and to find step-by-step instructions that walk you through this simple and free registration process.
