What is Outbound Spam?

An outbound spam is a malicious and illegitimate email sent from your network when compromised by spammers. If the problem goes unnoticed, internet service providers can block your network’s traffic. This will block your emails from reaching potential customers, and even if your messages make it through, your customer’s spam filter might get in the way.

Why is Outbound Spam a Problem?

If spammers infiltrate your network with outbound spam, you can find your network flagged as a source of spam messages. Most of your emails will get filtered out by many mail servers. As a result, a legitimate email can end up not reaching its intended destination.

Other consequences of outbound spam messages include:

  • Damage to your company’s reputation
  • Wasted bandwidth and slower connection speeds
  • Trouble sending legitimate bulk emails

How to Protect Your Company Email

The main causes of outbound spam are compromised email addresses and machines or networks infected by malware. Luckily, there are many ways to protect your networks and computers from the risks of outbound spam. Consider these anti-spam strategies:

  • Enable notifications that can alert you whenever anyone sends outbound spam emails. Some systems can even block users from sending compromised emails.
  • Manually review and monitor all the complaints from your ISP. Fortunately, some email services like Yahoo usually notify users when it detects outgoing spam.
  • Install an outbound spam filter to scan all emails sent from your network, identify illegitimate messages, and shut down or block their source.

Pro Tip: If you suspect someone is using your company’s email to send spam messages, keep an eye on your internet usage. If the records show a level you know you didn’t reach, it’s possible a hacker is piggybacking off your network.

Don’t be an Accidental Spammer

Unknowingly sending spam messages will damage your company’s reputation, compromise your security, place your clients at risk, and make legitimate business difficult. Don’t let this happen to you! Keep your work network secure and watch for any signs of suspicious outgoing messages.
