How this service works
DKIM public key for selector "dkim2" of a domain: looks up dkim2._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 dkim2 selector will verify. $0.01 per lookup.
Output
Returns parsed details from the dkim2._domainkey.<domain> TXT record including the DKIM version tag (v=), key type (k=), public key length in bits, whether the domain is in testing mode, and whether the key has been revoked (empty p= field). Confirms whether mail signed with the dkim2 selector will successfully verify.
Example use cases
Pre-send DKIM validation check
“Before we start our email campaign, check whether the dkim2 DKIM selector is properly set up for our domain sendgrid-customer.com — confirm the key exists, isn't revoked, and isn't in testing mode.”
Email deliverability audit
“I'm auditing email configuration for acme.io — can you pull up the dkim2 DKIM selector record and tell me the key type, public-key length, and whether it will actually verify mail signed with that selector?”
DKIM revocation detection
“Has the dkim2 DKIM key for mailchimp-user.net been revoked? Check the dkim2._domainkey DNS TXT record and let me know if p= is empty or if anything looks wrong.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/dkim2?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to inspect the 'dkim2' DKIM selector for a domain — for example when an email provider uses dkim2 as its designated selector (common with Sendgrid, custom setups, or multi-selector configurations). Prefer this over generic DNS TXT lookups when you need structured DKIM field parsing (key type, length, revocation status) rather than raw DNS output.
Side effects
- Domain does not have a dkim2._domainkey TXT record — returns not found or empty result
- DNS resolution failure via Cloudflare DoH — returns error or timeout
- Malformed TXT record that cannot be parsed — returns parse error
- Revoked key detected (empty p=) — returns revoked status rather than key details
- Network or upstream DoH service unavailability
