About the IP & Domain Blacklist Checker
Spam blacklists (DNSBLs) are databases of IPs and domains that sent spam or hosted malware. Inbox providers consult them: one listing on a major list can send all your email to spam or get it rejected outright.
Enter a domain and Nuqti finds its website IP and mail server IPs, then checks them on 20 IP blacklists — plus the domain itself on 5 domain blacklists — showing a clear listed/clean grid.
