If you use email as a means of communication, it is quite certain that at some point it happened to you that your inbox became the target of strange emails that you did not ask for or wanted to receive. The definition of such e-mails is SPAM.
What Are SPAM Messages?
In addition to marking a mailbox full of any things you didn’t want, spam in the email world is also a synonym for anonymous, massive, and unexpected email. In short, it is a message that is sent to the recipient without his or her permission, which, among other things, may contain fraud, virus, or other malicious code that may pose a potential danger to the recipient.
The basic forms of spam messages range from fake private messages that can lead to adult content, various “get rich quick” schemes (such as Nigerian fraud), to the promotion of products or services for which recipients have not shown interest.
The Presence Of SPAM Messages With E-mail Users
An interesting fact is that at one point in 2010, almost 80% of all sent emails were spam. When it comes to countries that are leading this practice – according to the survey two years ago, almost 13.21% of all spam messages came from IP addresses located in the US, followed by China with 11.25%. Last year, the situation is such that nearly 45% of all emails sent were spam in some form.
As a result of these statistics, as well as the fact that spammers are becoming more sophisticated when it comes to their “work” – spam filters are getting smarter and more rigid. Therefore, legitimate emails can end up in the junk folder. You may have experienced a situation where the message you sent did not end up in the recipient’s inbox, and vice versa – that you expect a specific email from a known recipient, but that it ended up in your spam folder.
There are some steps you can take to make sure that the messages you send end up in the right place. But first, we need to see what a spam filter is and how it works.
What Is A Spam Filter?
Itr is a system for searching and scanning email messages. If the filter finds something suspicious in the subject line or content of the message, the email is automatically marked as spam and usually ends up in the spam folder.
How Does Spam Filter Work?
The information the filter takes into account can be divided into three categories.
1. Where the message came from
Anti-spam organizations have created special lists called the RBL. RBL stands for Real-Time Black List. This is a collection, that is, a list of IP addresses that are well-known for sending SPAM messages. Using an RBL list, the filter compares the IP address from which the email was sent, with the IP addresses from the list. If a spam match occurs, the sent message rises and the ability to end it in spam is increased.
2. Who sent the message?
Using email captions, filters check whether the email was sent by a spammer or an actual sender. Each email has a unique ID, but when spammers send a group of emails all messages have the same ID.
3. What does the message look like?
The spam filter analyzes the content and topic of the entire email. If the composition consists of phrases such as “buy now”, “lowest prices”, “click here”, etc. – email can be identified as spam. Also, the filter looks for striking HTML such as large fonts, flashing text, bright colors, and similar performance. On the other hand, many filters compare the whole text with the number of suspicious words. That means, for example, that if you send a long email – it will not be identified as SPAM because there are few suspicious words.

Filtering technology is not all-powerful, but your awareness of precautions is a great complement. This means first of all avoiding leaving your e-mail address in places where it is not necessary, or camouflaging it wherever possible. Be sure not to participate in discussions in forums and newsgroups under your real e-mail address!
If you own the domain, the problem with spam is much more serious. However, as a domain owner, you also have better options for controlling spam messages. You just need to carefully plan your appearance on the Web.
For starters, with each sign in to a website – seek authentication with a new email address, such as putting the name of the site you are logging in in front of the @ sign. You will certainly receive mail sent from this site, and if you later find yourself needing to reject mail that arrives at it, you will simply set up filters.
You will also know which site is the “culprit” for the spam flooding that may have occurred. Therefore, you will be able to take other actions based on that fact.
