About Blacklist Lookup

People who want to check if the IP address is added on the blacklist or anti-spam database can use the free blacklist lookup tool designed by FreeSEOToolBox.

FreeSEOToolBox has designed the blacklist lookup tool to test the IP address of the mailer server against the DNS-oriented email blacklist. In case the mail server is blacklisted, you might not be able to send the emails. The IP addresses are generally blocked to reduce the chances of spam.

There are no limitations when you have to look up the IP addresses. In simpler words, you can look up one IP address or a hundred, there is no limit.

No, there is no need to create an account to use this tool by FreeSEOToolBox. This is because the tool is free to use and you can use it without any subscription as well.
