SPAM: What are so-called spam emails and what are their types?

When a person creates an email account they do so in order to exchange messages with their acquaintances or friends. But, you should know that when you have it it is common to receive dozens of messages that were never requested and that are not of our interest.

These emails constitute the very famous “Spam” that we have all heard about as Internet surfers. This phenomenon increases day after day, and as new solutions and technologies emerge to counteract it, spammers dedicated to their work become increasingly sophisticated and modify their skills, in order to avoid user counter-measures.

In order to inform you on this topic, in the article below we will give you some details about junk mail and the types that exist. In addition we will explain you better the purpose for which many practice this phenomenon and how to recognize it.

What is SPAM or spam and what is its purpose?

SPAM is called the form of supersaturating the Internet with many copies of the same message, with the aim that they reach people who would never otherwise agree to receive them.


Originally this word cataloged those spam or junk emails that arrived without being requested, however, the concept has been extended by the many forms of online communication that exist today.

correo basura o correo no deseado

Usually, this propaganda is sent in large numbers to millions of accounts at the same time, and the majority of publicists instead of investing in campaigns and advertisements on popular websites, take advantage of this medium and collect email addresses from public or private sources, to which they will later send promotional emails in a matter of minutes.

Obtaining a considerable profit if only a small part of these receivers end up buying the product. It should be noted that Spain with 0.7% occupies the nineteenth position of the top 20 of the main countries that send spam.

As a curious fact we mention that the terminology “Spam” has its origin in World War II, when the American company Hormel Foods launched its canned meat called “Hormel’s Spiced Ham”, which means ham with spices From whose contraction the word in question arises.

origen de la palabra spam

This meal was very popular among American and British troops, since it saved the use of the can opener. But, it is in 1970 when the kings of British humor, The Monty Python’s in their sketch, describe it as annoying, repetitive and inevitable.

This is because when trying to order food in a cafeteria, all the dishes on the menu contained the food, which became somewhat invasive.

It is then, when almost half a century later, this description is not funny at all and fits perfectly with those emails or advertising shipments that are received on the Internet.

What are the main forms of SPAM that exist?

As we have already said, You can consider spam to all the ads, images or links that we often find on the websites. But what ways are there to find it?

Here we mention them:

Adult advertising

Normally, it includes offers of products designed to increase or improve sexual potency, erotic or pornographic ads that direct the user to paid sites or with subscriptions.

It is an illegal data collection technique that consists of duplicating web pages making the user believe that it is in the original. This is commonly done with bank pages where notices are sent to access them. In this case, what hackers do is update data such as passwords, expiration dates, account numbers, etc.


Propaganda about health and medicine

They are carried out by miraculous products, magic therapies or shamans that they say surpass the medicine and nutrition specialists. These are usually published in magazines that use “before and after” montages.

On what platforms can we find unwanted messages?

As there are no perfect anti-spam measures that completely protect a means of communication, no platform is exempt from suffering from this problem that not only spreads in the most popular, but also reaches the least frequented and more private than there are.

In what follows, we will show you the most bombarded by the subject in question:


It is also considered junk mail when a user posts something that has nothing to do with the group’s topic of conversation. Likewise, when a person repeatedly sends messages solely for the purpose of increasing their rank or number of messages in the forum.

Although it is not a platform, we can mention it as one of the ways to find this, especially in cities, as it is very common to find while we walk ads on walls, posts, cars, among other structures.

SPAM risks on the Internet Why is it so bad?

This pile of junk mail is not only annoying because the mailbox is filled with unwanted messages, but can also become very dangerous.

While it is true that this does not belong to the group of virtual attacks and is used more frequently for marketing purposes, many cybercriminals can also use it as a means to distribute malware to the devices and steal access data to user accounts. In particular to online banking services through techniques of phishing or phishing.

More than 40% of spam aims to steal personal information for illegal purposes, which can lead to significant economic damage to the user. For this reason it is clear that it does not always have commercial purposes.

We can classify online criminals basically into two groups. Scammers who send deceptive advertising or sell “miracle products”, and hackers who use emails as a means of virus distribution that can give you full access to the receiver’s device.

How can I protect myself from messages and spam?

  • Use alias accounts: Do not use your primary email account in newsgroups, guestbooks or forums; If not, use alias accounts that you can delete after using them. You just have to spread your private account to people you really want to communicate with.

  • Implement anti-spam software on your computers: You have the possibility to configure your account so that all incoming messages are rejected through anti-spam software. These have built-in intelligent software filters to recognize these messages and move them from the inbox to the junk mail folder.
