How to Stop and Block Spam Emails: The Ultimate Guide

We use email every day we are online. We subscribe, we communicate with people, and our first interactions with services start with providing our personal email during registration. All internet marketing masterminds could not ignore this, so we all are familiar with getting unwanted mail, AKA spam — let’s give this term a more profound definition. 

Spam emails are unwanted and unsolicited messages sent in bulk to a large number of recipients. The name “spam” actually came from a Monty Python skit where they sang a song about canned meat, repeating “spam, spam, spam” over and over again – this repetition and annoyance is similar to how people feel about unwanted emails clogging up their inbox. Spam emails have been around almost as long as the internet, with the first sent in the late 1970s. Over the years, they’ve evolved from simple text messages to more sophisticated advertising campaigns, often containing malicious links or attachments. The easiest method to not be tricked by them is to stop ads altogether using an ad blocker like AdLock. That will stop a heaping amount of junk. But to block spam emails from other sources, you will need to do extra steps you’ll find in this article.

Most Popular Types of Spam Letters

What just does not come into our mailboxes. Unwanted job offers, winning promises and payments from unknown payment systems, warnings of having been sued or blocked. This happens to everyone — here are some of the most usual types of spam letters: 

  • Spam with malware

Especially dangerous are spam messages that contain malicious programs such as viruses, worms, or Trojans in attachments or in HTML code. Moreover, such software can also be used to connect your PC to a botnet designed to send spam. Another type of this is the advertising of illegal products. For example, pornography, illegal goods, drugs with restrictions, user databases, fake software. 

  • Phishing

Using phishing messages, spammers try to extract confidential information — bank account numbers and passwords — to use them in their machinations. Attackers use the names and logos of well-known companies, such as banks, as bait.

  • Chain letters
Chain letters

Chain Letters are letters in which the user is asked to copy the letter and forward it to as many addresses as possible. Chain Letter usually begins by grabbing the user’s attention with phrases such as “don’t erase this letter, be sure to read it.” The longer the chain – the more real email-addresses spammers get into their malicious network!

  • Letters of happiness

Such a letter promises the email user literally “all the blessings of the earth” — love, health, wealth. All that is needed for this is to forward the letter to other people. The more new letters are sent out, the more happiness you will receive. While such letters appear to be a gesture of good will, in reality, they can help spammers get not only more emails into their usage, but, when reaching someone’s work mailbox, also get a glimpse of an internal structure of the company. Not to mention they spot the most vulnerable and easiest to be manipulated workers. This was mostly used in the old days, as well as the so-called Nigerian letters that were not mentioned in this article. 

  • Opt-in letters

Opt-in is a type of commercial mailing for which the user must register, i.e. confirm your desire to participate in the mailing list and independently indicate your mailing address. Such mailing assumes the user’s voluntary participation and interest and gets spammers a place to send even more unwanted mail.

It’s important not to interact with the spam email in any way, as it may confirm to the sender that your email address is active and result in even more spam. Additionally, do not download any attachments or click on any links from unknown or suspicious senders, as these can contain malware or viruses.

    Why am I suddenly getting a lot of spam emails?

    When you suddenly experience an increase in the amount of spam you receive, you should be cautious and check if your email address is publicly accessible on websites where you have an account. Spammers often search websites for email addresses that are visible in plain text and add them to their lists for bulk spamming. To prevent this, some people prefer to display their email addresses as an image, which makes it harder for spammers to find and add them to their lists. It is also possible that the increase in spam may be a result of previously interacting with spam emails.

    How do I spot spam e-mails?

    Rule #1: No legitimate organization/company/service will send emails from an address that ends with “” (not even Google) as their corporate email addresses always have their domain name at the end of the email address.

    Rule #2: Check if the domain name is misspelled. The tricky part is that it goes unnoticed at first. Check the email address of the sender before opening the letter.

    Rule #3: The text is poorly written. Spam is usually created and distributed by non-native English speakers so the text inside contains errors, misspellings, typos, etc, etc. Professionals would never allow themselves to send bad texts.

    Rule #4: Never open or download attachments to the suspicious letter. And never click any links too. But if you do, you’ll bet a bunch of malicious scripts settled all over your device.

    Is Opening a Spam Email Dangerous?

    If you accidentally open a spam email, it may notify the sender that your email is active. This can lead to more spam. Hidden images in spam emails can also be dangerous, as opening the email may subscribe you to an unsolicited mailing list. It’s best to ignore and immediately delete unwanted emails and not open attachments from unknown senders to avoid viruses.

    How to permanently stop spam emails on Gmail?

    Unfortunately, there is no way to stop spam emails permanently. No matter how many layers of privacy you put on, eventually, spammers will get you. But you can significantly reduce the number of junk in your inbox by marking emails as spam without even opening the letters by following these steps:

    • Go to your Gmail inbox;
    • Find the email you want to mark as spam;
    • Select the checkbox next to the email;
    • Click on the “Report Spam” button located on the top toolbar.

    This will mark the selected email(s) as spam and move it to the Spam folder. Gmail will then use this information to identify future similar emails as spam and automatically move them to the Spam folder. You can also stop ads in Gmail to give your inbox an even tidier look.
