How this service works
DKIM public key for selector "mj" of a domain: looks up mj._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 mj selector will verify. $0.01 per lookup.
Output
Returns parsed fields from the mj._domainkey.<domain> TXT record including the DKIM version tag (v=), key type (k=), public key algorithm, public key bit length, whether the testing flag (t=y) is set, and whether the key is revoked (empty p= field), plus a confirmation of whether mail signed with the mj selector will successfully verify.
Example use cases
Mailjet DKIM setup verification
“We just set up Mailjet for sending transactional emails from acme.com — can you check that the mj DKIM selector is correctly published and not revoked, and tell me the key type and length?”
Email deliverability audit
“I'm auditing the email authentication records for example.com — can you pull the DKIM key for the mj selector and tell me if it's valid, what algorithm it uses, and whether testing mode is on?”
DKIM revocation detection
“Check whether the mj DKIM selector on newsletter.org has been revoked — I need to know if the p= field is empty before we send our next campaign.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/mj?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to inspect the DKIM configuration for the 'mj' selector (commonly used by Mailjet) on a domain. Prefer this over generic DNS TXT lookup endpoints when you want pre-parsed DKIM fields (key type, length, revocation status, testing flag) without having to parse the raw TXT record yourself. Choose sibling selectors (yahoo, protonmail2, zendesk2) if checking those respective providers instead.
Side effects
- Domain has no mj._domainkey TXT record — returns not found or empty result
- DNS resolution failure via Cloudflare DoH — network or upstream error
- Malformed TXT record that cannot be parsed into DKIM fields
- Domain does not exist — NXDOMAIN response
- Payment not provided — 402 Payment Required response blocking the lookup
