How this service works
DKIM selector lookup for Security review: Look up a supplied DKIM selector under _domainkey. DNS data only; does not send email or verify that an inbox exists.
Output
Returns raw DNS TXT record data for the specified DKIM selector under _domainkey for the given domain, including the public key, key type, version, and any other DKIM tag-value pairs present in the record. Does not send email or verify mailbox existence.
Example use cases
Email deliverability audit
“I need to check if our DKIM selector 'mail' is correctly published in DNS for acme.com — can you pull up that DNS record so I can confirm the public key is there?”
Security review of third-party sender
“We're onboarding a new email vendor and their selector is 's1024'; can you look up the DKIM record for their domain sendgrid.net under that selector so I can review the key strength?”
Incident response DKIM check
“We're investigating a spoofing incident — can you look up the DKIM selector 'default' for the domain suspectdomain.io so I can see what public key they have published?”

Side effects
- DKIM selector does not exist in DNS — returns empty or NXDOMAIN response
- Domain does not exist in DNS — DNS resolution failure
- Selector string malformed or domain string invalid — input validation error
- DNS timeout or temporary resolution failure — transient network error
- DKIM record exists but is malformed — raw unparsed data returned
