Stop spam emails and outsmart them across different platforms using the tips and tricks in this article. Dive in!
Spam Emails: How to Block Them?
The world-renowned tech company, Cisco, defines spam emails as:
[…] unsolicited emails sent in bulk. Spam is usually associated with risky business schemes, offensive messages, and chain letters.
However, not all bulk messages are spam—especially permission-based ones.
Spams are rarely direct emails from advertisers. They’re usually from a spamming party bound by a deal between them and the legit advertiser.
Also, there are many ways spammers find your email address. They can buy your email address or collect them from brands or programs.
Learning how to block spam mail is the best way to prevent spammers from reaching you again.

The Dangers of Spam Messages
Spam emails often bring malicious intent to their recipient. Know the potential dangers of spam messages through this list:
1. Spyware
Spyware tracks your online activities like email, usernames, passwords, bank information, etc. It is the easiest way to obtain and use your data for a hacker’s gain.
Spam emails usually contain spyware that is activated when you click a link in the message.
🎉 Fun Fact Spyware can cause so much damage that 23,903 people lost $347 million from tech support scams in 2021. You must be cautious when dealing with suspicious emails as they may contain spyware. |
Fraudsters pose as legitimate tech support. They send a compromised email offering to resolve issues like software license renewal or bank updates.
Once you give in to the attacker’s request to download or click a link, they will install spyware on your device.
2. Phishing
Phishing emails are so common that it affects one in every five people online. These emails are from someone who poses as a legitimate organization to ask for your personal information.
Several phishing scammers acted as event organizers during the 2018 World Cup in Russia. They stole email addresses and other information through continuous spam messages.
✅ Pro Tip It is easy to spot a phishing email. If you are not expecting an email from an individual or a group and the email address is different or suspicious, it may be a phishing message. |
3. Ransomware
Ransomware is malware that encrypts your data and holds it for ransom. Downloading or clicking a link from a ransomware-embedded mail can lock your device.

Unlike spyware, you will immediately know when ransomware infects your device. The most common sign is that you can’t access your files.
A ransom note will appear on your computer screen or in all your files. The request would mainly involve money in Bitcoins.

Protect Yourself From Spam Emails
Sometimes, blocking isn’t enough to prevent spam from creeping into your mailbox.
You need to reduce your email addresses’ exposure to prevent spam from coming back. Here are some preventive tips to consider:
1. Modify your email privacy settings
Blocking a spam message is an effective prevention from returning junk emails.
Changing your email privacy setting is even better. It lowers your exposure to spam in the first place.
One way to keep your email private is to not share your email address with organizations you don’t know.
✅ Pro Tip Set up multi-factor authentication to secure your mailbox. Most platforms offer this type of security to avoid hacking and other cyberattacks. |
2. Use complex passwords
It’s inconvenient to memorize long and complex passwords, so people tend to set easy ones. Most use the same password for all their accounts.
If you want to keep your email secure, make sure not to include the following when creating a password:
- Consecutive numbers or characters
- Personal information like birth date or house address
- Easy-to-guess keystroke patterns
These are good ideas for creating a password for your email and other accounts:
- Create a complex combination of arbitrary alphanumeric and special characters. Make it as unique as you can.
- Make it long. Short passwords can be easy to guess.
🔓 Security Note There’s a chance you won’t remember most of your passwords. However, never write your passwords on paper. You can use a secure and efficient tool to handle all your passwords in one place. Try using a trusted password manager like Passwarden. |
3. Use several email addresses
Having several email addresses lessens cybersecurity risks. This way, you can secure your data and avoid the dangers of spam emails by directing them away from any valuable personal information.
✅ Pro Tip You should have a primary email involving sensitive data. This data includes banking, shopping, work, and personal contacts. Use a secondary email for subscriptions or mailing lists. |
Conclusion
Nothing is more annoying than constantly clearing junk messages in your electronic mailbox. However, it’s terrifying to discover that someone robbed you because of a link you clicked.
Spam email is an entry point for cybercriminals. Outwit them by blocking or junking emails to secure your digital footprint.
