Manage Email Spam


Microsoft Outlook and Gmail automatically filter suspected spam and move it to your Junk Email or Spam folder. You can also block unwanted senders, allow trusted senders, and adjust spam filtering settings using the tools available in your email account.

If you are receiving threatening, abusive, or harassing messages, do not rely solely on spam filtering. Princeton University provides resources and reporting options for electronic and online harassment.

Block a sender or mark messages as junk

You can manage blocked and safe sender lists using:

If you use another email application, such as Outlook for Mac, Apple Mail, Thunderbird, or a mobile mail app, use Outlook on the web to manage your blocked and safe sender lists. This ensures your settings are saved directly to your Exchange account.
