How this service works
DKIM public key for selector "mailgun" of a domain: looks up mailgun._domainkey.<domain> (TXT, Cloudflare DoH) and parses v=, k=, key type, public-key length, testing flag and whether the key is revoked (empty p=). Confirms that mail signed with the mailgun selector will verify. $0.01 per lookup.
Output
Returns parsed details from the mailgun._domainkey.<domain> DNS TXT record, including the DKIM version tag (v=), key type (k=), public key and its bit length, whether the key is revoked (empty p=), and whether the testing flag is set — confirming if Mailgun-signed mail will pass DKIM verification.
Example use cases
Pre-send mailgun deliverability check
“Before I send our campaign through Mailgun, can you verify that acmecorp.com has a properly configured mailgun DKIM key — is it valid, what type is it, and is the key revoked or in test mode?”
Email authentication audit
“I'm auditing the email security setup for newsletter.io — can you look up their mailgun DKIM selector and tell me the public key length and whether it will actually pass DKIM verification?”
Diagnosing bounced mailgun emails
“We're getting DKIM failures for messages sent through Mailgun from ourdomain.com — can you check the mailgun DKIM selector to see if the key is missing, revoked, or misconfigured?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/mailgun?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate the 'mailgun' DKIM selector for a domain — ideal for email deliverability checks, security audits, or diagnosing Mailgun-specific DKIM failures. Prefer it over generic DNS TXT lookups when you want structured parsing of DKIM fields (key type, length, revocation status) rather than raw record text.
Side effects
- Domain has no mailgun._domainkey TXT record (selector not configured)
- DNS resolution failure via Cloudflare DoH (network or upstream error)
- Malformed TXT record that cannot be parsed
- Key is revoked (empty p= field), indicating DKIM will fail
- Rate limiting or payment failure ($0.01 per call via x402)
