How this service works
Does the domain's SPF record authorise xero to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for xero'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 the domain's SPF record authorizes Xero, the specific SPF mechanism that matched (e.g. include:spf.protection.xero.com), and the complete SPF TXT record retrieved via Cloudflare DoH.
Example use cases
Verify Xero onboarding email setup
“We just set up Xero for invoicing at techstartup.io — can you check if our SPF record actually authorizes Xero to send emails from our domain so invoices don't land in spam?”
Audit domain for unauthorized Xero sender
“I didn't set up Xero for our domain globalventures.com but someone flagged an email from Xero — can you check if our SPF record is authorizing Xero to send on our behalf?”
Pre-launch email deliverability check
“Before we go live with Xero billing for clients, confirm that the SPF record on mybusiness.co.uk includes Xero's sending infrastructure — I need to make sure the integration is correct.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/xero?utm_source=zero.xyzWhen to prefer
Use this endpoint specifically when you need to confirm whether Xero is authorized as a sending source in a domain's SPF record, particularly during Xero integration setup, email deliverability audits, or vendor sender discovery. Prefer this over generic SPF parsers when you want a direct yes/no answer about Xero authorization without building your own SPF parsing logic.
Side effects
- Domain has no SPF TXT record — returns no authorization with an empty or null record field
- Domain does not exist or DNS lookup fails — DNS resolution error returned
- Malformed SPF record that cannot be parsed — may return inconclusive result
- Rate limiting or payment failure — 402 or 429 response
- Xero's SPF include mechanisms change over time, potentially causing false negatives if the check list is stale
