How this service works
Does the domain's SPF record authorise gusto to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for gusto'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 boolean indicating whether Gusto is authorized by the domain's SPF record, the specific SPF mechanism that matched (e.g. include:gusto.com or an IP range), and the complete raw SPF TXT record retrieved via Cloudflare DNS-over-HTTPS.
Example use cases
Verify Gusto payroll email setup
“We just integrated Gusto for payroll and employees should be getting emails from us through it — can you check if our domain techstartup.io has Gusto listed in its SPF record so emails don't bounce?”
Audit domain for unexpected senders
“We didn't intentionally set up Gusto for our domain oldcompany.com — can you check if Gusto is somehow authorized in our SPF record? I want to make sure there's no misconfiguration.”
Pre-launch deliverability check
“Before we go live with Gusto for HR communications at newbrand.co, can you confirm that Gusto is properly authorized in the SPF record so their emails won't end up in spam?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/gusto?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly verify whether Gusto specifically is authorized as an email sender for a domain, as part of deliverability audits, vendor integration checks, or security reviews. Prefer it over generic SPF parsers when the sole question is Gusto authorization — it returns a direct yes/no answer with the matching mechanism rather than raw DNS data requiring further interpretation. Ideal for automated compliance pipelines or agent-driven email configuration audits.
Side effects
- Domain has no SPF TXT record — returns no authorization with empty record
- Domain does not exist or has no DNS — DNS lookup failure
- SPF record is malformed or exceeds lookup limit — parsing error returned
- Network/DoH timeout from Cloudflare resolver
- Domain parameter missing or invalid — request rejected
