Secure Message Center Help

General Information

What is the Secure Message Center?

Secure Message Center is a secure webmail application, hosted by ZixCorp, which allows the recipient of encrypted emails sent by ZixCorp’s customers to read the encrypted email in its decrypted form. The messages are typically encrypted to protect sensitive information, such as personal health information (PHI) or personal financial data. ZixCorp customers can have their company branding on the webmail page or they can use a generic webmail page that is branded by ZixCorp as the ZixMessage Center.

When a message is sent via Secure Message Center, a notification email is sent to the recipient (see example below). If this is the first time the recipient received an encrypted email from that sender’s company, then the recipient will need to create an account (your email address and a password) in order to read the message. If the recipient has previously received encrypted messages from the sender’s company, then the recipient will only be required to re-enter their password to open and read the message.

I have just received my first secure message and don’t know my login.

You will need to establish an account in order to read your secure message. Your username is your email address.  If you have multiple email addresses you will need to use the address that the notification was sent to.

To establish a new account:

From the Secure Message Center login page, select the “New to Secure email? ‘Register’” link to create your account. The Register Account screen that follows requires you type your email address and your new password twice. Click the “Register” button. A confirmation email is sent to the email address you provided.

When I click on the link to read my secure message, nothing happens.

Some browsers and mail clients may not support active links. It’s also possible the link has been modified or is being blocked. If any of these appear to be the case, you will have to copy and paste the entire URL, located at the bottom of your email, into the browser window. This may take more than one copy and paste effort. 

Additionally, if you already had a browser window open, it’s possible the browser did open correctly and is simply behind another open application.

Reading & Replying

Can I save or download my secure message before it expires?

You can download or print any Secure Message and all attachments from the Secure Message Center.  This includes emails in your Sent Mail folder.

To download the message:

The email I received has expired. How do I get it back?

If the message has expired or has been deleted, there is no way to access it.  Due to the security features of the Secure Message Center, the original sender of the message must re-send it.

When a message expires without being read, an expiration notification email is returned to the sender. The sender has the option to resend the message at that time.

You can attach up to 10 different files with a total size of 15 MB.

Note that the larger the size of the file, the longer it may take to upload and download.
