How this service works
Does the domain's SPF record authorise sendinblue to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for sendinblue'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 indicating whether Sendinblue is authorized, the specific SPF mechanism that matched (e.g. an include or IP entry), and the complete SPF TXT record retrieved via Cloudflare DNS over HTTPS.
Example use cases
Verify Sendinblue onboarding for new domain
“We just set up Sendinblue for acmecorp.com — can you confirm the SPF record is actually authorizing Sendinblue to send before we launch our campaign?”
Audit domain for unexpected email senders
“I want to audit newsletterco.io's SPF record to check whether Sendinblue is unexpectedly authorized to send mail on their behalf — can you look that up?”
Troubleshoot Sendinblue deliverability issue
“Our Sendinblue emails from mybrand.com keep landing in spam — can you check if the SPF record is actually including Sendinblue's sending infrastructure?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/sendinblue?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify Sendinblue authorization in a domain's SPF record — for example, confirming an ESP integration is correctly configured, auditing for unauthorized senders, or troubleshooting Sendinblue deliverability issues. Prefer this over generic SPF lookup tools when you want a structured yes/no answer scoped to Sendinblue rather than raw DNS data.
Side effects
- Domain has no SPF TXT record — returns no with empty record
- SPF record exists but does not reference Sendinblue — returns no with full record for inspection
- DNS resolution fails via Cloudflare DoH — returns error indicating lookup failure
- Malformed SPF record that cannot be parsed — may return partial result or error
- Domain does not exist — DNS NXDOMAIN causes lookup failure
