A website may also be listed on the blacklist. This is where the site administrator sends thousands of emails to advertise a product. If one of the email recipients introduces it as spam, the email service provider may place the website in a blacklist. That's why if you send a promotional email and you've recently noticed that your visitors are less likely, one of the reasons may be blacklisted. Also, many organizations run Blacklist Services on the Internet. Service Providers can check that the website is on the blacklist with DNSBL or SURBL. The Blacklist Lookup tool allows you to check your website in blacklist.
