DNS checker
A DNS lookup tool checks the public DNS records for a domain and explains what those records mean. Use this free MailParse tool to inspect A, AAAA, MX, TXT, CNAME, NS, and CAA records with extra context for email deliverability.
Type a domain such as example.com. The tool removes protocols, paths, and trailing dots automatically.
Select All records for a broad DNS check, or choose one record type such as MX, TXT, or CAA.
Compare Google DNS and Cloudflare DNS responses, then use the email checks to spot missing MX, SPF, or DMARC records.
A DNS lookup tool queries public DNS resolvers and shows the records published for a domain, such as A, MX, TXT, CNAME, NS, AAAA, and CAA records.
MX records route incoming mail, SPF records in TXT limit authorized senders, DKIM records sign messages, and DMARC records tell receivers how to handle failed authentication.
Different resolvers can cache records at different times. If a DNS change is recent, wait for the record TTL to expire and check again.
TTL means time to live. It tells DNS resolvers how many seconds they can cache a record before asking for a fresh copy.
Yes. Run an all-record lookup to see SPF TXT records on the root domain and an automatic DMARC check at _dmarc.yourdomain.com.
Validate the records that affect inbound delivery and sender trust.
MailParse receives inbound messages, parses MIME into structured JSON, and verifies authentication signals before sending clean data to your app.
