Check IP Addresses, Email, Subnet, Domain for Spam in Blacklists Database

CleanTalk provides lists of spam active IP & Email addresses which were seen by the service in spamming on the websites, and lists of domains that are promoted using spam. Often, many spam bots send out messages disguised as normal and can be very difficult to define what spam is. You can check the IP/email of questionable users in our lists to find out their spam activity.

Check IP and Email for Spam Activity

Spam active IP can participate not only in spamming but also to participate in other types of attacks, such as fraud, DoS, DDoS, SQL and PHP injections, etc. and email addresses can be used to send spam via email.

Black SEO

• This will be useful in the definition of spam in messages if the text messages there is a link with the domain from the list, then with high probability this message is spam.
• Also you can check your domain to make sure that it is not moving with the use of black SEO. Some SEO companies may use black SEO to promote the site and place links using spam. As a result, you will receive a report about the presence of thousands of links, but then you can lose credibility and get penalties from search engines.
• When you buying a domain will also be useful to check the history and reputation of the domain. It is quite possible that before the sale of the domain, the domain was promoted by placing links in spam comments.

How Does the CleanTalk Database of Spam IP & Email Work

Blacklisted IPs, emails, domains are being put into the database automatically based on spam activity of anyone who posts something on the Internet. Database records are being created in real-time.

The CleanTalk Anti-Spam and Security Services analyze data of IP and mail addresses activity and if they have such spam activity on several websites for a certain amount of time then after reaching the critical activity threshold the IP/email will be blacklisted.

The service gets data of activity from more than 320,000 websites in real-time. This allows us to discover new spam IPs and emails in short time periods and keep high data relevance for already caught spam IPs/emails.

Each email address is checked for existence. That makes possible to blacklist fake emails within a few hours after we get the first spam check request.

Information about blacklisted records is very accurate as data of spam activity were received from different websites simultaneously.

How Is It Helpful for Hosting Companies

Hosting companies monitor their clients' website activity for the purpose of preventing of spam mailing, but not all hostings keep an eye on spam that goes towards other websites in form of spam comments, spam posts and spam contact form data. If other websites are being spammed there are two reasons why this is happening:

1. Server was bought by spammers for spam activity.
2. Client's website or server have malicious software that send spam.

It's rather difficult to discover this sort of behavior as you have to monitor all incoming POST and GET requests from the website or server and investigate them to understand whether it is a spam or the result of work of a web application.

What's the easiest way to discover spam activity of a website or a server? Check IP addresses via Black Lists.

How Is It Helpful for Email Marketing Services

Clients give the lists of emails of their website subscribers but some of them are spammers. At the same time spammers often use email databases of real clients or non-existent emails. A company that didn't check emails from such list risks that its IP could be blacklisted or the letters would considered as spam. But it is possible to check email lists via the CleanTalk Database and if some emails have spam activity that means that most likely a subscriber was a spammer and such emails should be deleted.

Check IP address or email address via CleanTalk DataBase for spam activity or if they have been blacklisted. It will be helpful to prevent malicious activity and fraud.
