How this service works
DKIM public key for selector "marketo" of a domain: looks up marketo._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 marketo selector will verify. $0.01 per lookup.
Output
Returns parsed fields from the marketo._domainkey.<domain> TXT record including: the v= (version), k= (key type, e.g. RSA), the public key itself, the public key bit length, whether the testing flag (t=y) is set, and whether the key is revoked (empty p= field). Confirms whether Marketo-signed mail will pass DKIM verification.
Example use cases
Verify Marketo email deliverability setup
“We just configured Marketo for acmecorp.com — can you look up the marketo DKIM selector and confirm the public key is present, not revoked, and what key type and length it's using?”
Audit domain before Marketo migration
“Before we switch our email platform, check if newsletter.brandco.com already has a marketo DKIM selector configured and whether the key is valid or empty.”
Diagnose Marketo email signing failures
“Our Marketo emails from techstartup.io are failing DKIM checks — can you pull the marketo._domainkey DNS record and tell me if the key is revoked, in testing mode, or missing?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/marketo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify the Marketo DKIM selector configuration for a domain, as opposed to other DKIM selectors (e.g. Shopify, Google). Ideal for email deliverability audits, pre-send checks for Marketo campaigns, or diagnosing DKIM authentication failures in Marketo-originated mail.
Side effects
- Domain has no marketo._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 — partial or error response
- Revoked key (empty p= field) — returned as revoked status rather than an error
- Payment not completed — x402 payment required error before lookup proceeds
