How this service works
DKIM public key for selector "sfmc" of a domain: looks up sfmc._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 sfmc selector will verify. $0.01 per lookup.
Output
Returns parsed details from the sfmc._domainkey.<domain> TXT DNS record including: DKIM version (v=), key type (k=), public key presence and length in bits, whether the domain is in testing mode, and whether the key is revoked (empty p= field). Confirms whether mail signed with the sfmc selector will pass DKIM verification.
Example use cases
Salesforce Marketing Cloud email setup audit
“We just configured Salesforce Marketing Cloud for acme.com — can you check if the sfmc DKIM selector is properly published, and tell me the key type, length, and whether it's active or revoked?”
Email deliverability troubleshooting
“Our Salesforce Marketing Cloud emails from brandco.com are going to spam — can you pull the sfmc DKIM selector record and tell me if the key exists, is valid, and isn't in testing mode?”
Pre-send domain authentication check
“Before we launch this email campaign from newsletter.mystore.com through Salesforce Marketing Cloud, check the sfmc DKIM selector and confirm the public key is present and not revoked.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/sfmc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to verify or audit Salesforce Marketing Cloud (SFMC) DKIM configuration for a domain. It is purpose-built for the sfmc selector rather than generic DKIM tools, saving parsing effort and providing structured output including revocation and testing-mode flags. Prefer it over generic DNS TXT lookups when the goal is confirming SFMC email authentication readiness.
Side effects
- Domain has no sfmc._domainkey TXT record — returns not-found or missing record
- DNS resolution failure via Cloudflare DoH — network timeout or upstream error
- Domain has an empty p= value indicating a revoked/disabled key
- Malformed TXT record that cannot be parsed into standard DKIM tags
- Invalid or non-existent domain input — DNS NXDOMAIN response
