How this service works
Does the domain's SPF record authorise calendly to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for calendly'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 Calendly is authorized by the domain's SPF record, the specific SPF mechanism (include/ip) that matched (if any), and the complete SPF TXT record retrieved via Cloudflare DNS-over-HTTPS.
Example use cases
Verify Calendly onboarding email setup
“We just set up Calendly for our team and I want to make sure our domain acme.com has Calendly properly authorized in its SPF record so scheduling emails don't get flagged as spam — can you check?”
Audit vendor email authorization
“We're doing a quarterly email security audit. Can you check whether the SPF record for clientco.com includes Calendly as an authorized sender, and show me the full SPF record?”
Detect unexpected Calendly sender
“I received a scheduling email claiming to be from meetings@partnerdomain.com through Calendly — can you check if partnerdomain.com's SPF record actually authorizes Calendly to send email for them?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/calendly?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to verify Calendly's presence in a domain's SPF record for deliverability auditing or vendor integration checks. Prefer this over generic SPF parsers when the question is narrowly about Calendly authorization rather than full SPF record analysis.
Side effects
- Domain has no SPF TXT record — returns no authorization found
- Domain does not exist or DNS lookup fails — returns DNS error
- SPF record is malformed or exceeds lookup limit — may return incomplete result
- Calendly not found in SPF — returns no with null mechanism
