Every day we receive email messages, notifications, and calls from unknown numbers. The word spam has become part of everyday language—and no, we’re not talking about the canned meat product.
But what does it actually mean? Why are we constantly targeted by these unwanted communications? And most importantly: how can we block spam calls or stop our inboxes from being flooded with spam emails?
This article takes an in-depth look at the spam phenomenon, examining its impact on cyber security, privacy, and digital device usability. We’ll also explore effective countermeasures to block spam numbers, identify fraudulent messages, install a good anti-spam filter, and use third-party apps.
All this in a practical and updated approach suited to everyday users of Android, iOS, or Windows operating systems.
What spam means and where the term comes from
The word spam has an unusual origin: it comes from a famous Monty Python comedy sketch where the word “spam” was repeated so many times that it became annoying. From there, it began to be used to describe repetitive, useless, and annoying messages.
In the digital world, spam refers to any unwanted electronic communication sent to a large number of recipients.
Spam makes up the majority of unsolicited messages we receive, including:
- Spam emails with intrusive advertising
- Spam messages via WhatsApp or SMS
- Spam calls from unknown or foreign numbers
- Scams disguised as irresistible offers
Today, spam targets both private users and businesses, with billions of messages circulating daily.
Example
In the United States it’s estimated that over 45% of daily emails are spam, generating illegal revenues worth millions of dollars.
Spam emails: a daily threat to personal data
The most common form of spam is still email-based—and often in overwhelming volumes. Email addresses are frequently harvested by bots, bought on dark web forums, or extracted from compromised old databases. Users who enter their email addresses on unsafe websites risk becoming constant targets.
Spam emails often contain:
- Fake promotions or fraudulent offers
- Phishing attempts posing as banks or services
- Requests for login credentials
- Links to malicious software or infected attachments
In some cases, a single mistaken click can compromise your entire device or expose sensitive personal data. That’s why modern email providers offer anti-spam filters, but they’re not always enough.
Suspicious spam: how to spot dangerous messages
Suspicious emails are often labeled as “suspicious spam.” But what should you do if you receive one? The golden rule is: don’t open, don’t reply, don’t click.
A suspicious spam message can usually be identified by:
- Unknown senders or strange-looking email addresses (e.g., info@1x4a-bnb.ru)
- Generic subject lines like “You won!” or “Urgent!”
- Requests for personal information or links to external pages
- Attachments with strange extensions (.exe, .scr, .zip)
These messages are designed to deceive, steal information, or infect your system with malware.
How to block spam calls on iPhone and Android
Spam calls are another major channel used for scams and aggressive marketing. They may come from real call centers—or from robots simulating conversations through auto-dialing systems. Blocking these numbers is now a priority.
Here’s how to block spam calls on iPhone:
- Go to Settings > Phone
- Enable “Silence Unknown Callers”
- Or use apps like Hiya, Truecaller, or RoboKiller
To block spam calls on Android:
- Open the Phone app
- Tap the three dots > Settings > Caller ID & Spam
- Enable “Filter Spam Calls”
- Install a third-party app for stronger protection
Blocking each phone number manually is a good first step, but apps allow for more automatic and accurate control.
Best apps to block spam numbers
Today, several third-party apps are available to block spam numbers, both for Android and iOS. Some are free, while others offer premium features.
Top-rated apps include:
- Truecaller
Real-time identification and spam call blocking - Hiya
Updated collaborative database - CallBlocker

Uses user reviews to rate calls
These apps also include features like personalized blacklists, crowdsourced spam reports, and automatic blocking of suspicious area codes (e.g., numbers from Nigeria or the United States).
WhatsApp blocked for spam: what it means and how to avoid it
It’s increasingly common for users to find their WhatsApp blocked for spam. But why does it happen?
If you send promotional content, chain messages, or message many users not saved in your contacts, WhatsApp may interpret this as spam behavior and temporarily or permanently block your account.
To avoid being blocked:
- Don’t message people who don’t know you
- Avoid using WhatsApp for aggressive marketing
- Follow the guidelines in the app’s official policy
Getting WhatsApp blocked for spam is a serious issue, especially for those who use it for work. In some cases, the block may last several days—or become permanent.
Spam and cyber security: the real risks
Spam isn’t just annoying—it’s potentially dangerous. Cybercriminals use it to spread malicious software, run phishing campaigns, and launch large-scale malware attacks.
The risk increases when a message appears legitimate but is actually a trap, such as:
- Emails that imitate communications from banks, the tax office, or Amazon
- SMS pretending to be delivery notifications
- Fake contests with clickable prize links
Behind many cases of identity theft, data breaches, or unauthorized access to bank accounts, you’ll often find a successful spam message.
How to protect yourself from spam: final tips
Fighting spam requires a multi-layered and mindful approach:
- Don’t share your phone number or email address with untrustworthy websites
- Activate a reliable anti-spam filter for your email
- Use third-party apps to block spam calls
- Be skeptical of unsolicited messages, especially those with links or attachments
- Keep your operating system and antivirus software up to date
- Avoid clicking “unsubscribe” on suspicious emails—it may confirm your address is active
In conclusion, spam is one of the major digital threats of our time. Not only is a large portion of online unwanted communication made up of spam, but it also serves as a dangerous vehicle for cyberattacks and financial scams.
