Protecting your email from spam



Exede and Wildblue's email service includes an extensive, community-based spam email protection program explained here. We also show you how to block specific email addresses and domains from your inbox.

Important information about email:
Viasat continues to support the WildBlue and Exede email services but Viasat Internet does not offer an email service. We recommend using Google’s free Gmail as the most full-featured and secure email service available. You can continue to access your WildBlue and Exede email at or

Worried about email spam? We’ve got you covered.

In addition to settings that will block specific email addresses from ever reaching your inbox, our Zimbra-based email service is designed with behind-the-scenes spam protection.

Zimbra partners with the Cloudmark antispam/antivirus engine, which runs on a community platform. That means it doesn’t block email based just on Viasat customer concerns, but all the customers that use it. Cloudmark protects about one billion subscribers’ email accounts from spam, viruses, phishing, and similar threats.

Cloudmark effectively blocks spam by first creating identifying “fingerprints” for every message.

When users click the spam button to indicate a particular message is unwanted, that report is delivered to Cloudmark.

It essentially sends up a red flag about the sender. When the number of email user complaints hit a specific level, Cloudmark finds the common fingerprints within those reports: URLs, phone numbers, originating IP addresses etc. Those fingerprints are then tagged as bad or “spam”, and any subsequent message containing a bad fingerprint won’t be accepted. 

This system relies on user feedback. The more users mark unsolicited email as spam, the greater the chance it will be blocked. So instead of just deleting your junk mail, tag it as spam; Cloudmark will take it from there.

Cloudmark has ample experience in threat protection. It partners with Cisco, McAfee, and Microsoft, and key customers include AT&T, Verizon, Swisscom, Comcast, Cox and NTT. 

Blocking messages

You can also take matters into your own hands and block messages from specific email addresses or domains.

To do so, log in to your email account.

Here are a few other easy ways to help prevent spam emails:

  • Use two separate email addresses. Reserve one for personal and the other business and other non-personal senders. Then be judicious about who receives the personal address.
  • Uncheck those boxes. Anytime you enter your email address on an shopping or contest site, you'll typically see a pre-checked box that allows companies and their partners to send you emails. Make certain to uncheck these boxes, preventing any unwanted email from comng your way.
  • Use a unique email address.  It will make you harder to find. Spammers gamble on finding valid email addresses by sending millions of messages to probable name combinations through large ISPs and email services. A unique address is far less likely to be included on their guess list. 
  • Keep security current to avoid falling victim to a malware scan.  Hackers and spammers troll the internet looking for computers that aren’t protected by up-to-date security software. When they find unprotected computers, they try to install hidden software known as malware that lets them control these computers remotely. Thousands of these computers linked together form a “botnet ,“ a network used by spammers to send millions of emails simultaneously. Unbeknownst to their owners, millions of home computers are part of botnets.
