What is spam? 
Spam is unsolicited commercial email (from legitimate or illegitimate sources), recognizable by its suspicious subject lines and unexpected or unknown sender. In short, it's all that pesky unwanted email.

What risks are involved?
For the most part, spam is an annoyance. Spam often contains questionable content and may include attachments that contain viruses.

How can I reduce the amount of spam I receive?

  • Customize your campus spam filtering settings.
  • Set up filtering in your email client (the program you use to manage and access your email, such as Outlook).
  • Set up Allow/Deny lists.
  • DO NOT respond directly to the mail. Generally, doing so merely verifies your address.

What is UC Davis doing to protect me?

Despite the best filtering efforts, however, spam may still slip into your inbox. Inventive spammers create new variations of spam that can slip through the cracks in existing filters. Thus, there is often a window of time during which new spam is not yet recognized by filters and, and for a little while, a new iteration of spam will find its way to inboxes.
