How this service works
Is this IPv4 address listed on spamcop (bl.spamcop.net)? Performs the DNSBL query (reversed octets under bl.spamcop.net, via Cloudflare DoH) and returns listed yes/no with the return codes and, where the list publishes one, the reason text. One list, one precise answer. $0.01 per lookup.
Output
Returns whether the queried IPv4 address is listed on SpamCop's DNSBL (bl.spamcop.net), including the DNSBL return codes and, where published by SpamCop, a human-readable reason text explaining why the IP was listed.
Example use cases
Email deliverability pre-check
“Before I send our marketing campaign, can you check if our mail server IP 198.51.100.10 is listed on SpamCop so I know if it might get blocked?”
Inbound SMTP sender reputation check
“We're getting suspicious emails from 192.0.2.55 — can you check if that IP is on the SpamCop blacklist and what reason is listed?”
Automated abuse investigation
“I need to know if the IP 203.0.113.77 that's been hitting our contact form is flagged on SpamCop's DNSBL — listed or not, and any return codes you find.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/blacklist/spamcop?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, single-list check specifically against SpamCop (bl.spamcop.net) for an IPv4 address, particularly for email deliverability checks or spam source investigation. Prefer this over multi-list aggregators when SpamCop listing status is the specific signal required, or when you want the raw return codes and reason text from SpamCop directly.
Side effects
- Invalid or non-public IPv4 address provided — may return error or undefined result
- DNS resolution failure via Cloudflare DoH — transient network error
- IP not found in SpamCop list — returns listed: false with no reason text
- Rate limiting or payment failure — returns 402 or access denied
