SURBL

What is SURBL?

SURBL is a tool that allows you to check if the domain name or the IP of your website is blacklisted for sending unsolicited email messages. SURBLs are lists of websites that have appeared in emails reported as SPAM.

How To Use SURBL? (Features)

• SURBL List – This list records all potential websites which are responsible for fraud and illegal activities. This list is thorough and ensures that your safety is improved to 95% to counter these spam websites. Your data can be leaked if you do not filter out these websites and the company’s name could be compromised. 
• SURBL Fresh – This feature points out new domains that are prone to hacking and illegal activities. These are the ones that are recently added to TLD zone file delegations and are often most vulnerable to risks. This preemptive measure allows your online content to be managed seamlessly without any security issues. Furthermore, this list includes a UNIX timestamp to help you track the changes made on these websites, and avoid those websites before any mishap happens. 
• SURBL Shorter Domain List – This is self-explanatory as it records URL shorteners. Often these URL shorteners are used to hide spam websites that are sent in emails. These spam websites will eventually compromise your valuable data using verified URL shorteners.
• SURBL UriQ – This feature checks full URLs that are genuine but may be compromised. These websites are trusted but are affected by security issues and are hacked. Data breaches are often accounted to trusted websites that have been in control of spammers. For your customers to be careful, you need to filter out such websites which may seem legit but eventually, will compromise user privacy. For your business to grow efficiently, using this feature is a must.
