Master the art of detecting spam emails and keeping your digital life secure.
Every day we are facing different types of spam emails or messages, be it our workspace or personal email id. Spam can be defined as an unsolicited message that may or may not have a malicious bias. Referring a message as malicious, we’re talking about scams and frauds. These annoying messages that clutter our inboxes, phones, or social media are not just irritating — they can also be dangerous. They often include scams, viruses, or links that could steal your data or harm your device.
Let’s break down what spam is, the different types you should watch out for, how to spot it, and most importantly — how to protect yourself.
Why Is Spamming a Cybersecurity Risk?
You might think, “Spam is just annoying, not dangerous.” But here’s the thing: spam can actually open the door to cyberattacks.
A spam message could:
- Contain links to malware-infected websites
- Trick you with phishing tactics (like pretending to be your bank)
- Spread ransomware through malicious attachments
- Harvest your personal data for identity theft
Common Types of Spam to Watch For
Spamming isn’t just limited to emails anymore. Here are the most common forms you might come across:
Email Spam: This is the classic. Think bulk emails from unknown senders with weird subject lines. They might offer fake discounts, dubious investment opportunities, or shady links.
Social Media Spam: Ever seen random accounts commenting “Get rich quick!” under posts? That’s social media spam. It can also include suspicious messages in your inbox from strangers.
SMS Spam (Smishing): Getting texts from unknown numbers offering prizes or claiming your account is compromised? That’s SMS spam, and it’s often used in smishing attacks (SMS phishing).
Instant Messaging Spam: Apps like WhatsApp and Telegram are popular targets for spammers. They might send you malware links or impersonate someone you know.
Comment Spam Blog comment sections and forums often get bombarded with spam links. The goal here is usually to promote a site or gain SEO backlinks.
Search Engine Spam Some individuals attempt to artificially boost their website’s rankings on search engines using unethical methods. Techniques like keyword overuse and creating networks of irrelevant backlinks—commonly known as link farming—are employed to deceive algorithms into assigning higher visibility to low-quality sites.
Spam Phone Calls Although not purely digital, spam via phone calls is a widespread nuisance. Automated messages (robocalls) and unwanted telemarketing often bombard people with unrequested offers, scams, and fraudulent schemes that can sometimes result in monetary loss.
Fax Spam Despite being an outdated form of communication, fax machines are still targeted by spammers. These unsolicited faxes often contain promotional content or advertisements, consuming paper, toner, and time.
Forum Spam Just like blogs, discussion forums and community platforms are vulnerable to spam. Malicious users frequently post promotional content or harmful links that disrupt conversations and degrade the quality of interaction within the community.
Junk Mail (Physical Spam) Traditional postal services aren't exempt from spam either. People often receive uninvited promotional materials, misleading advertisements, or irrelevant offers through physical mail—commonly referred to as "junk mail.
Pop-Up Ads Although not as dominant as other forms of spam, pop-up ads that unexpectedly appear while browsing can be equally disruptive. These ads typically push products or misleading offers, hindering the user experience.
Self-awareness is the best self-defence to prevent digital spam
Email spam may seem like just a modern nuisance, but it's also a gateway for scams, malware, and data breaches. Being aware of how spammers operate can help you avoid falling for their tricks.
-
Promotional Spam (Ads)
You’ve likely received random emails selling random products or weight loss pills. While some offers might be legit, many are scams designed to trick you into clicking or buying something shady.
-
Chain Emails
You’ve probably seen emails/messages that say something like, “Forward this or something bad will happen.” These are just time-wasting tricks. Best to ignore them unless you enjoy a fake curse on your inbox.
-
Email Spoofing
Spoofed emails make it look like they’re coming from someone you know or a company you trust. In reality, they're fake and often dangerous.
-
Hoax Emails
These messages usually offer too-good-to-be-true promises, like “make millions in 30 days” or “lose 10kg while eating pizza.” They’re designed to catch your attention and lead you to suspicious websites.
-
Money Scams
Ever received a “Nigerian prince” email asking for a small loan or fake donation requests. That’s a classic money scam. Always double-check before giving money or info.
-
Fake Malware Alerts
These emails warn you that your device is infected with a virus or ransomware, claiming they have the fix. Usually, they’ll ask for your personal information or tell you to download a file—don’t fall for it. It’s a trick to infect your system.
-
Adult Content Spam
This type of spam is widespread because adult content gets attention—and spammers know it. They’ll send emails with explicit images or videos with harmful links. Avoid clicking, even out of curiosity.
-
Other Sneaky Spam Types:
-
Blank Spam: These contain no content at all and are often sent to see if your email address is active.
-
Image Spam: These emails use images with embedded links or text to sneak past spam filters.
-
Spear Phishing: Highly targeted scams that use your personal info to create convincing fake emails.
-
Clone Phishing: These mimic real emails or websites, making it hard to spot the fraud at first glance.
-
How to Identify Spam (And Avoid Clicking!)
Here are some common signs that an email might be spam:
- Strange Sender Address: Weird or unfamiliar email addresses.
- Suspicious Links/Attachments: Avoid opening anything you weren’t expecting.
- Too Good to Be True: Big rewards or offers that seem unrealistic.
- Requests for Personal Info: Legit companies don’t ask for passwords or sensitive data by email.
- Poor Spelling/Grammar: Many spam emails are badly written.
- High Frequency: Getting the same email repeatedly is a red flag.
- Low-Quality Media: Blurry images or broken links often mean danger.
What to Do if You Get a Spam Email
If you receive a spam email from a client's known email address, follow these steps:
- Verify with the Client: Don't assume the email is genuine. Contact them through another channel to check. If it's Spam:
- Don’t Click or Reply:Avoid clicking links or opening attachments.
- Report It: Use the “Report Spam” or “Mark as Junk” option.
- Block the Sender: Most email platforms let you block specific addresses.
- Let Them Know: If the email is indeed spam and the client's account was compromised, inform them so they can take appropriate security measures.
If it’s clearly a phishing attempt:
- Don’t Respond: Never give out info.
- Report as Phishing: Many email platforms have this option.
- Delete Immediately: Don’t keep risky emails in your inbox.
- Scan Your Device: If you accidentally clicked, run a malware scan.
Additional Security Measures:
Update Passwords: If you suspect the client's account was compromised, guide them to change their password and enable two-factor authentication.
Scan for Malware: If you have opened the email or clicked on a link, scan your device for malware.
Report to Authorities: If you suspect a serious phishing or scam attempt, consider reporting it to the relevant authorities like the Internet Crime Complaint Center (IC3).
There can be different solutions that protect your company against different types of email threats.
For example, Anti-Fraud Protection, a DMARC-based solution that protects your company’s domain. It prevents criminals from using your name and brand in spam. These tools not only help keep cybercriminals from impersonating you, but they also boost your email deliverability.
Techniques to send spam:
Spammers use different tricks to send spam. A few are mentioned below:
- Botnets:Networks of infected computers send out spam automatically.
- Snowshoe Spam: Spam spread across many IP addresses to avoid detection.
- Blank or Image Spam: Used to sneak past filters or test email activity.
Scams often feature one or more of these signs. Keep an eye out for these red flags:
- Authority:Is the email pretending to be from someone important—like a boss, bank, or government agency?
- Urgency: Are you being pressured to act fast, with phrases like “Click now or you’ll lose access!”?
- Emotion: Does the message try to stir up strong feelings like fear, anxiety, excitement, guilty or curiosity?
- Scarcity: Are you being told it’s “Limited-time offer!” or “Only 2 left!” to make you act quickly?
Tools & Tips to Protect Yourself from Spamming
Okay, so now that you know what spamming is and how it works, let’s talk defense. Here’s how to keep your inbox — and your data — safe:
- Use Spam Filters
Most email providers have built-in spam filters. Make sure yours are turned on and updated regularly. - Don’t Share Your Email Publicly
Enable DMARC for Business Emails. Avoid posting your email on social platforms or forums. - Unsubscribe Carefully
Clicking “unsubscribe” on legit newsletters is fine. But for suspicious emails? Don’t click anything — it might just confirm your email is active. - Be Wary of Unknown Links
If something feels off, it probably is. Never click on links or download attachments from unknown sources. - Use Multi-Factor Authentication (MFA)
Even if your email is compromised, MFA can stop hackers from accessing your accounts. - Update Your Software
Spam attacks often exploit outdated systems. Keep your OS, browser, and antivirus tools updated. - Report Spam
Help others by reporting spam to your email provider or messaging app. This trains the system to better filter spam in the future.
Conclusion: Don’t Let Spam Catch You Off Guard
Spam isn’t just a digital annoyance — it’s a real security risk. From phishing to malware, it can cause personal and professional damage. The good news? A little awareness and a few safety measures can go a long way.
Stay alert. Stay cautious. And remember: if something feels off, it probably is.
