Who sends spam and for what purpose?
Spammer is the one who sends out spam.
The spammer uses different methods to get long e-mail lists. These are usually robots or automatic programs than looking up these addresses all over the web.
How do they get the addresses?
- The web pages usually have the owner's email, but also visitors. In addition, they are published in forums, blogs,...
- The mailing listslike joke mail and chain mail. "Forward it to 20 friends and you'll be lucky" In many cases, users forward the email without hiding the addresses (Bcc reminder). Therefore, the addresses can be captured by malware, such as a Trojan horse.
- The web pages that request the email of the user to recommend it to their friends, to access services and downloads.
- There is data sets of company and private addresses for sale. This is illegal in many countries.
- The illegal entry into servers.
In addition, trial and error generates random email addresses. After sending, these messages are checked to see if they have reached their destination.
An example is making a list of domains and adding prefixes to them.
Web bugs and small images contained in the code HTML of the message help the spammer identify valid addresses.
This way, every time a recipient reads the message, it requests the image from the spammer's server. The spammer's server automatically logs it.
Objectives of Spam
Spam targets can be those of
Marketing, bidding and trying to arouse interest in a product
But you can also have criminal purposes.
That's why it can be dangerous to open an e-mail from an unknown address. It can be used to monitor the user, steal personal information.
The recipient's computer can even be used to launch computer attacks and send spam messages without the user's knowledge.

How to protect yourself from Spam
Having an anti-spam filter
Most email services and managers have their own anti-spam filter. Visit our hosting services page for more information.
We do not recommend sending chain letters. If you want to send or forward, you must do so using the Bcc, hidden copy option. This prevents the e-mail addresses from being seen.
The email publication on public websites makes it vulnerable. It should therefore be used with caution. A good practice is to create an email address for publication on public websites and a private email address.
We recommend do not open spam messages or preview them. Under no circumstances should it be answered. It is safer to delete messages from unknown addresses directly.
It is also not recommended to buy products offered in spam, to prevent fraud and reuses the email address in new spam campaigns.
