Reducing Spam Volume

There are several methods that individuals and organizations can use to reduce the volume of spam emails they receive:

  • Use an email filter: Many popular email providers have strong spam filters on by default. These filters can be adjusted to better suit your needs.
  • Block images in HTML messages: Spammers often use images as web beacons to track if an email has been opened. By blocking all images, you can reduce the amount of information spammers have about you.
  • Junk the Junk: A tracking pixel is a small and often invisible image loaded when a user opens an email which can be used to track if an email has been opened. By blocking these pixels, you can reduce the amount of information spammers have about you.
  • Choose a “Less-Guessable” Email Address: Spammers often use software that generates random email addresses. By choosing an email address that is less likely to be generated by this software, you can reduce the amount of spam you receive.
  • Be Cautious When Giving Out Your Email Address: Only give out your email address to people and organizations that you trust.
  • Use Antispam and Antivirus Software: Antispam and antivirus software can help block spam emails before they reach your inbox.
  • Train Your Spam Filter: Most spam filters allow users to mark emails as spam or not spam. By doing this regularly, you can help improve the accuracy of your spam filter.
  • Unsubscribe From Mailing Lists: If you no longer wish to receive emails from a mailing list, use the unsubscribe link at the bottom of their emails.
  • Use Temporary Mail: For any communication that is not important, you can use temporary mail services, such as 10-minute email.
