How this service works
Does the domain's SPF record authorise brevo to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for brevo'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 authorization flag indicating whether Brevo is authorized, the specific SPF mechanism that matched (e.g. 'include:spf.sendinblue.com' or an IP range), and the complete raw SPF TXT record retrieved via Cloudflare DNS-over-HTTPS.
Example use cases
Pre-launch deliverability check
“We're about to send our first email campaign through Brevo for clientdomain.com — can you verify that their SPF record actually authorizes Brevo so the emails won't get rejected?”
Post-migration DNS audit
“We just migrated clientco.com's DNS to a new provider and I need to confirm that the SPF record still includes Brevo as an authorized sender — can you check that?”
Unexpected sender security audit
“I need to audit whether Brevo is listed as an authorized sender in the SPF record for mybrand.io — we didn't set up any Brevo account and I want to make sure no one is spoofing us through them.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/brevo?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to verify Brevo (Sendinblue) authorization in a domain's SPF record, such as before launching a Brevo email campaign, after DNS changes, or during a security audit to detect unexpected authorized senders. It is more targeted than a generic SPF parser because it explicitly checks for Brevo's include mechanisms and IP ranges.
Side effects
- Domain has no SPF TXT record — returns no authorization with empty record
- Domain does not exist or DNS lookup fails — returns an error or no record found
- SPF record exists but uses redirect modifiers that obscure Brevo authorization
- Rate limiting or Cloudflare DoH unavailability causes lookup failure
- Malformed SPF record syntax may cause parsing issues
