Spamming has been around as long as the concept of the email itself. Some unwanted messages in your inbox may be innocuous, albeit ineffective, attempts to promote products or services. Others contain malicious links that expose your sensitive data when clicked. Fortunately, there is a way to improve the quality of email filtering.
The ubiquity of spam has given rise to websites dedicated to digital defense. Both suspicious email addresses and IPs (unique identifiers of all internet-connected machines) are included in blacklists. These databases are useful for recipients and senders alike.
Nowadays, the methods of cybercriminals are becoming increasingly sophisticated. Phishers and fraudsters use email to achieve their goals. Check out an IPs and emails database on https://cleantalk.org/blacklists/spam-ip, which is updated on a regular basis. Not only does the site collect user complaints. It also allows you to check if your own IP has been compromised.
It is vital to understand that the presence of a specific address on the list does not necessarily mean the owner is a spammer. Cybercriminals may use contact details of unsuspecting email users for their illegal actions. Therefore, victims of data breaches often remain unaware of any dubious activity.
Common Reasons For Inclusion
An IP could appear on the blacklist automatically or based on user complaints. The latter happens when more than 0.01% of recipients report you as a suspicious sender. Here is what can prompt them to do so:
— they cannot remember signing up for the mailshot;
— the messages have no “unsubscribe” link, or they fail to find it;
— their inbox is overloaded with messages;
— the content of your emails does not meet their expectations.
Companies launching digital promotion campaigns should also pay close attention to their mailing lists. These should be kept updated. Inactive email addresses are sometimes turned into “spam traps”.
How to Report
Many specialized websites established for cyber defense collect reports from individual users. For instance, on cleantalk.org, you may easily add to the blacklist. Just enter the IP or email address, specify the type of attack and type a comment if you wish. You can also leave your name and email if you want the company to get back to you.
Currently, the range of attacks includes the following:
- spam on websites;
- brute force attacks (attempts to crack login details);
- SQL Injections (embedding of malicious code into applications);
- fraud or phishing;
- web application attacks;
- DoS or DDoS attacks;
- spam by email;
How to Check Your Address
On the other hand, companies intending to launch any mailshot should run a check of their IP and domain. If either of these has been blacklisted, the messages will not reach the target audience. The check can usually be done through the same platforms that collect user complaints. It is also possible to eliminate your address from the list.
