How this service works
DKIM public key for selector "constantcontact" of a domain: looks up constantcontact._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 constantcontact selector will verify. $0.01 per lookup.
Output
Returns parsed details from the constantcontact._domainkey.<domain> TXT record including: DKIM version (v=), key type (k=), public key length in bits, whether the domain is in testing mode, and whether the key is revoked (empty p= field). Indicates whether mail signed with this selector will successfully verify.
Example use cases
Pre-send email deliverability check
“Before I send our campaign through Constant Contact, can you verify that the constantcontact DKIM record for mybrand.com is valid and not revoked so I know the emails won't fail authentication?”
New domain onboarding audit
“We just set up Constant Contact for newsletters.acmecorp.com — can you look up the constantcontact DKIM selector and confirm the key is there, what type it is, and its length?”
Diagnosing DKIM failures
“Our Constant Contact emails for clientdomain.org are failing DKIM — can you check the constantcontact._domainkey DNS record and tell me if the key is missing, revoked, or just misconfigured?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/constantcontact?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify Constant Contact DKIM configuration for a domain. It is more focused than a generic DKIM lookup because it targets the exact 'constantcontact' selector, parses all relevant fields, and explicitly flags revocation. Prefer it over manual DNS queries when you need structured output including key length and testing status without writing your own parser.
Side effects
- Domain has no constantcontact._domainkey TXT record — returns not found
- Key is revoked (p= is empty) — returned as a parsed revocation status
- DNS resolution failure via Cloudflare DoH — network or timeout error
- Malformed TXT record that cannot be parsed — parse error returned
- Domain input missing or invalid — input validation error
