How this service works
DKIM public key for selector "kl" of a domain: looks up kl._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 kl selector will verify. $0.01 per lookup.
Output
Returns parsed DKIM TXT record data for kl._domainkey.<domain>, including: DKIM version (v=), key type (k=, e.g. rsa or ed25519), public key length in bits, whether the key is in testing mode (t=y flag), and whether the key is revoked (empty p= field). Confirms whether mail signed with the kl selector will successfully verify.
Example use cases
Email deliverability audit for kl selector
“I'm troubleshooting email deliverability for acme.com — can you check whether the kl DKIM selector is active, not revoked, and what key type and length it's using?”
Pre-send DKIM verification check
“Before we send a campaign, can you confirm that the kl DKIM signing key for newsletters.mycompany.com is valid and not in testing mode?”
Security audit of domain DKIM keys
“I'm auditing the email security setup for techcorp.io — please look up the kl DKIM selector and tell me if the key is still valid or has been revoked.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/kl?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate or inspect the DKIM configuration for the 'kl' selector (used by email providers such as Klaviyo). Prefer this over generic DNS TXT lookup endpoints when you need structured parsing of DKIM fields (v=, k=, key length, testing flag, revocation status) rather than raw TXT record text.
Side effects
- Domain does not have a kl._domainkey TXT record — returns not found or empty result
- DNS resolution failure via Cloudflare DoH
- Malformed TXT record that cannot be parsed
- Empty p= field indicating a revoked key (returned as data, not an error)
- Invalid or non-existent domain input
