How this service works
DKIM public key for selector "sparkpost" of a domain: looks up sparkpost._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 sparkpost selector will verify. $0.01 per lookup.
Output
Returns parsed details from the sparkpost._domainkey.<domain> TXT DNS record, including the DKIM version (v=), key type (k=), public key data and its length in bits, whether the record is in testing mode (t=y), and whether the key is revoked (empty p= field). Also confirms whether mail signed with the SparkPost selector should pass DKIM verification.
Example use cases
SparkPost deliverability audit
“We just switched to SparkPost for sending email from acme.com — can you check if the sparkpost DKIM selector is properly configured, and tell me the key type and length so I know it's not revoked?”
Email security review
“I'm auditing the email security setup for clientdomain.org — can you look up their sparkpost._domainkey DNS record and tell me if the DKIM key is valid, what type it is, and whether it's in testing mode?”
Troubleshoot SparkPost signing failures
“Emails sent through SparkPost from mybrand.io keep failing DKIM verification — can you check the sparkpost selector DNS record for that domain and see if the key is empty or revoked?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/sparkpost?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify the 'sparkpost' DKIM selector for a domain, such as auditing SparkPost email sending configurations, troubleshooting DKIM signing failures for SparkPost-routed mail, or confirming that a domain's SparkPost DKIM key is active, non-revoked, and correctly typed. Prefer this over generic DNS TXT lookup tools when you need parsed, structured DKIM field output (v=, k=, p= length, testing flag) rather than raw record text.
Side effects
- Domain has no sparkpost._domainkey TXT record — returns not found or empty result
- DKIM key is revoked (empty p= field) — reported as revoked
- DNS resolution failure via Cloudflare DoH — network or upstream error
- Malformed TXT record — parsing errors or missing required tags
- Domain does not exist — NXDOMAIN response
