How this service works
Does the domain's SPF record authorise hubspot to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for hubspot'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 boolean yes/no indicating whether HubSpot is authorized in the domain's SPF record, the specific SPF mechanism that matched (e.g. include:hubspot.net), and the complete SPF TXT record string retrieved via Cloudflare DoH.
Example use cases
Verify HubSpot email integration setup
“We just set up HubSpot for marketing emails on behalf of ourcompany.com — can you check if our SPF record actually authorizes HubSpot to send, and show me the mechanism that matched?”
Audit domain for unexpected senders
“I need to know if HubSpot is authorized to send email for a competitor's domain, clientdomain.com — check their SPF record and tell me if HubSpot is listed as an allowed sender.”
Pre-launch deliverability check
“Before we go live with our HubSpot campaign, can you confirm that the SPF record for marketingco.io is properly configured to allow HubSpot to send mail, and give me the full SPF record too?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/hubspot?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly confirm whether HubSpot is specifically authorized as an email sender for a domain via SPF. Ideal for pre-send deliverability audits, vendor integration verification, or detecting unauthorized senders. Prefer this over generic SPF parsers when the specific question is HubSpot authorization, as it returns a targeted yes/no with the matching mechanism highlighted.
Side effects
- Domain has no SPF TXT record — returns no authorization and empty record
- Domain does not exist — DNS lookup fails
- SPF record is malformed or exceeds DNS lookup limit — parsing may be incomplete
- HubSpot not found in SPF — returns authorized: false with no matching mechanism
- Cloudflare DoH service unavailable — lookup times out or returns error
