Why am I getting so many spam emails?

Sending spam emails is a low-risk high-reward activity 

The primary reason you’re getting so much spam email is because of the nature of email itself. It’s cost-effective and safe to send an email from any corner of the world, and sending millions of unsolicited messages a day is a low-risk high-reward scheme for a bad actor.

Marketers can promote to countless people with the click of a button, while scammers only have to trick a few out of the many people receiving their malicious spam (malspam). Cybercriminals sitting on the other side of the world can send malware, knowing that law enforcement is unlikely to come after them.

Some spam targets the email addresses of prominent organizations for extra high rewards. The objective of such emails is to take over official email accounts for a business email compromise (BEC) attack. BEC attackers can make off with millions in a single scam.

Although BEC is highly lucrative for scammers, law enforcement is fighting back. In early 2023, they recovered 800K from a BEC attack, stolen from a construction management company.

Your email address was exposed

There are several ways spammers can obtain your email address:

  • Bots: Spammers use bots to find email addresses. Bots crawl the internet, checking websites, message boards, and public social media pages for your contact information.
  • Subscriptions: If you signed up for a mailing list or promotion, your email address may have been sold to a spammer. Opening scam emails can also land your address on more spam lists, because scammers will know it’s a live email address and that you tend to open emails.
  • Dark webAuthors of spam emails can purchase email addresses on the dark web for low prices.
  • Brute force: Spammers can leverage brute force attacks like dictionary attacks to generate different combinations of email addresses.
  • Malware: Some viruses, worms, Trojans, and spyware can steal email addresses. Ultimately, some of these email addresses end up on spam lists.
  • Data breach: A data breach at a website you’ve signed up with can expose your email address to bad actors.

Spammers are getting smarter 

Although spam filters have steadily improved since the early 2000s, the percentage of email spam keeps rising. Not only are spammers sending out more emails but they’re finding ways to outsmart spam filters.

11 steps to stopping spam emails

It’s almost impossible to completely stop receiving spam emails. Even if spam doesn’t land in your inbox, it should go to your junk folder. However, there are some tools and practices you can utilize to manage spam.

  • Urgency: Malicious spam may try to trick recipients by creating a sense of fear or urgency.
  • Unrecognized senders: Spam is unsolicited. If you don’t recognize the sender, it might be spam.
  • Unprofessional: Some spammers don’t take the time to remove spelling or grammatical mistakes. The graphics in a spam email may also appear skewed.
  • Attachments: Spam emails can carry attachments such as files disguised as malware. The email may claim that these files are free software.
  • Phishing links: Spam may try to convince you to open a link. While some of these links look legitimate, others are poorly disguised and may appear as a string of numbers. If you’re in doubt, it’s best to not click the link at all.

Lottery or prize 

Spam emails sometimes inform users of fake lottery wins.

Fake tax refunds

The email usually appears to be from a trusted organization like a tax agency or retailer and carries a fake invoice. The email may state that the time to pay the invoice is running out. It may even threaten the user with account closure or law enforcement.

Should you be worried if you get spam emails? 

There’s usually no reason to worry about receiving spam emails. But you should avoid engaging with spam emails. Malspam can carry all types of nasty files that attack your security and privacy. Spam emails may also try to trick you into sharing confidential information or lead you to scam websites designed to copy your private information, such as your password or credit card number.

You should only be concerned if you have engaged with a malicious spam email. Depending on the scope of the threat, you may need to:

  • Change your passwords and the answers to secret questions.
  • Run an antivirus scan.
  • Monitor your credit cards, bank accounts, and next credit report for unusual activity.
  • Monitor your social media, email, and other accounts for unusual activity.

Another situation to be wary of is a spam attack. Sometimes threat actors send many junk emails to a target to flood their inbox, so they get frustrated and ignore security alerts. Scan your email regularly for security alerts if you notice an unusual spike in spam in your inbox.
