How this service works
DKIM public key for selector "brevo" of a domain: looks up brevo._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 brevo selector will verify. $0.01 per lookup.
Output
Returns parsed details from the brevo._domainkey.<domain> TXT record including: the raw record, DKIM version (v=), key type (k=), public key data, public key length in bits, whether the testing flag is set, and whether the key is revoked (empty p= field). Confirms whether Brevo-signed mail will pass DKIM verification.
Example use cases
Confirm Brevo email setup before launch
“We're about to start sending marketing emails through Brevo from ourbrand.com — can you verify the brevo DKIM selector is set up correctly and the key isn't revoked?”
Diagnose Brevo email deliverability issue
“Customers are reporting our Brevo emails landing in spam for techstartup.io — can you check if our DKIM brevo selector record is valid, what key type it uses, and whether it's in testing mode?”
Audit third-party email signing keys
“I'm auditing DNS records for clientdomain.net and need to know the details of their Brevo DKIM public key — key length, type, and whether it's active or revoked.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/brevo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify the Brevo (formerly Sendinblue) DKIM selector for a domain, as opposed to generic DKIM or other ESP-specific selectors. Ideal for email deliverability audits, Brevo onboarding validation, or monitoring whether a domain's Brevo signing key remains active and non-revoked.
Side effects
- Domain has no brevo._domainkey TXT record — returns NXDOMAIN or empty result
- DNS lookup fails due to Cloudflare DoH unavailability
- Malformed TXT record that cannot be parsed as a DKIM key
- Domain input is invalid or missing
- Key is present but revoked (empty p=), which is returned as a parsed result rather than an error
- Payment not completed — returns 402 before executing lookup
