How does an Anti-SPAM work? Principal functions

They work by scanning all the messages that come to you, where in turn these are qualified around certain characteristics. Depending on the score, the release may or may not be considered spam.

After analyzing those who have entered, these can be: blocked, deleted or sent to the “Spam” folder. When they are marked as “Deleted”, it is not entirely true, since they are sent to the corresponding folder.

What are the types of Anti SPAM that exist and how are they different?

What are the types of Anti SPAM that exist and how do they differ

There are two main types of anti spam, these are:

In addition to this, we can see other varieties of filters, such as:

Bayesian antispam filters

Bayesian filters work primarily with experience, and They are learning from those messages that the users themselves mark as such. So they need other people to be effective and improve. That is, if the user qualifies an email as such, what they will do is compare those marked emails with others and create a database to discard them at once.

This type of filters can raise the alert by means of words or the use of some effects, for example: the word “FREE” is capitalized or the use of bold fonts with colors, bold or with yellow shading.

The lists they use are generated by detecting patterns, starting from the e-mails that were manually marked as spam. So that In some cases, non-junk mail may be marked as spam and appear in the spam tray.



Blacklists exclude any message that comes from certain IPs. These are databases that show addresses where bad actions have been performed, such as mass mailing.

It works by mail servers that check if it is hosted there, in order to know whether to accept or reject the received mail. The problem arises when it cannot differentiate if these are sent voluntarily. So you may find yourself in one of them for no reason.

The reasons can be the following:

  • You may have sent a message to a spamtrap or trap mail, these are emails that the email service providers have created and have no activity. They use it as an alarm method, to catch spammers.
  • Your email has been hacked and they have sent messages automatically.
  • Your computers were infected by a virus that constantly sends emails to anyone.

Email firewalls

Firewalls also known as firewalls, they are nothing more than systems in charge of restricting the unauthorized access of certain elements. Those work by rules that are established by the provider and its administrator. They generally use a combination of Bayesian filtering, blacklisting, and others to prevent spam.

So this will make all messages received or sent, go through the firewall that will be in charge of examining each message, and if they do not meet any of the security criteria, they will be blocked.

Challenge / response filters

Although these are not as widely used, there are many that still implement them. It works in the following way; if you send an email with this filter, and still the contact is not on that person’s friends list or notebook, you will be considered a stranger. In such a way that you will be labeled as a spammer.

This to verify that you are or not, what it does is that an automatic response is sent to you with a question to answer or a link that you must enter, to prove that you are not a robot. In case of being labeled as such, it only remains to talk to the recipient to include you on their list.

Anti-spam filters that are based on your reputation

Reputation depends, as it says, on your position, that is, on the scores that the sender’s identification acquires. This filter is based on the sending IP address and the name of your domain used in sending the e-mails. If you do not have a reputation, they will be watching you, as this will measure your actions and that of your followers.

If you get a good reputation, you will get a good percentage from the people who open your campaigns and links in email messages.
