What is Spam404?
Spam404 is a community-driven project tracking spam websites, malicious domains, and abuse infrastructure. Their blocklist is publicly available and widely used by web hosting providers and email service operators to identify and block known spam and malicious domains. A Spam404 listing signals to web hosts and email providers that your domain is associated with spam or abuse activity.

What a listing means for your business
