Email Records Lookup (MX / SPF / DMARC)
IPOK dev tools provide fast network diagnostics and data conversions, including IP purity, subnet risk, DNSBL blacklist, and ASN routing lookups.
Want to know if a domain's email setup is complete? This tool checks MX, SPF, and DMARC at once. Your browser sends the query directly to Cloudflare DoH; it does not pass through IPOK, but Cloudflare processes it.
SPF / DMARC are policy (who may send, what to do with forgeries) — the baseline. But whether mail lands in the inbox or spam comes down to whether the sending server IP is clean: datacenter or not, on a spam blacklist (DNSBL), its reputation. Good policy won't save a dirty IP. So after the records, check the sending IP's purity.
The queried domain is sent directly from your browser to Cloudflare DNS for DoH and does not pass through an IPOK lookup endpoint. SPF / DMARC are policy, while sending-IP reputation also affects deliverability.
