How this service works
Does the domain's SPF record authorise twilio to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for twilio'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 Twilio is authorized in the domain's SPF record, the specific SPF mechanism that matched (e.g. an include or ip4/ip6 mechanism), and the complete raw SPF TXT record retrieved via Cloudflare DNS over HTTPS.
Example use cases
Verify Twilio email integration setup
“We just set up Twilio SendGrid for transactional emails on our domain acme.com — can you confirm that Twilio is actually authorized in our SPF record so emails won't end up in spam?”
Audit domain for unexpected senders
“I'm doing a security audit on example.com and want to know if Twilio appears in the domain's SPF record as an authorized sender — can you check and show me the full SPF record?”
Pre-launch deliverability check
“Before we go live with our Twilio email campaigns for myshop.io, can you verify that Twilio is properly included in the SPF record so our emails will actually be delivered?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/twilio?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a targeted, single-vendor check specifically for Twilio's authorization in an SPF record. It is ideal for verifying that a Twilio email integration is correctly configured for deliverability, or for detecting unauthorized Twilio sender presence in a domain's SPF. Prefer this over generic SPF parsing tools when the specific question is Twilio authorization.
Side effects
- Domain has no SPF TXT record — returns no authorization and an empty or null record
- Domain does not exist or DNS lookup fails — returns an error or null result
- SPF record exists but is malformed — may return unparseable record
- Network or Cloudflare DoH unavailability — may return a timeout or service error
