DNS & Email Lookup
A one-stop diagnostic for any domain — DNS records, mail configuration and blacklist status.
About this tool
Enter a domain to run a full set of DNS and email checks: A, AAAA, MX, NS and TXT records, plus the SPF, DKIM and DMARC policies that decide whether a domain's mail is trusted. It also runs a blacklist (DNSBL) check against the resolved mail server.
It is the fastest way to verify a new domain's mail setup, debug deliverability problems, or confirm that published records match what you intended. Lookups are performed from our server against public DNS.
