What is IP blacklisting?

Every server has an IP address that defines its location on the internet. As for your emails, they are sent from an email delivery service to be sent to the receiving services such as Gmail. If your IP is listed on a blacklist this may be due to the reputation of your ISP (Internet Service Provider) itself.

What is Domain blacklisting?

Domain blacklisting is a degradation in the reputation of the domain itself. Most often this is caused by sending emails that have been classified as “spam”.
