How this service works
Does the domain's SPF record authorise marketo to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for marketo's include/ip mechanisms, returning yes/no, the matching mechanism and the full record. Confirms a vendor integration is wired for deliverability, or spots an unexpected sender. $0.01 per lookup.
Output
Returns a yes/no answer indicating whether Marketo is authorized by the domain's SPF record, the specific SPF mechanism (e.g. include:mktomail.com) that matched, and the complete SPF TXT record retrieved via Cloudflare DoH.
Example use cases
Verify Marketo onboarding email config
“We just set up Marketo for our domain mybrand.com — can you confirm the SPF record actually authorizes Marketo to send email on our behalf, and show me the matching mechanism?”
Audit domain for unexpected senders
“I'm reviewing the email setup for clientdomain.com and I want to know if Marketo is authorized in their SPF record — I'm checking for any unexpected or rogue senders.”
Pre-send deliverability check
“Before we launch our Marketo campaign, can you verify that the SPF record for ourcompany.com includes Marketo so our emails won't get rejected?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/marketo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-purpose check specifically for Marketo SPF authorization on a given domain. Prefer it over generic SPF parsers when the question is precisely 'is Marketo wired up correctly for deliverability?' or when auditing a domain for unexpected Marketo-related sending. At $0.01 per lookup it is cost-effective for per-domain spot checks or small-scale audits.
Side effects
- Domain has no SPF TXT record — returns no authorization with empty record
- Domain does not exist or DNS lookup fails — DNS error returned
- SPF record exists but contains no Marketo-related mechanisms — returns no with full record
- Malformed SPF record that cannot be parsed — may return partial results or error
- Network timeout reaching Cloudflare DoH — lookup failure
