How this service works
Does the domain's SPF record authorise mandrill to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for mandrill'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 Mandrill is authorized by the domain's SPF record, the specific SPF mechanism (include, ip4, ip6, etc.) that grants the authorization if found, and the full raw SPF TXT record retrieved via Cloudflare DNS-over-HTTPS.
Example use cases
Confirm Mandrill deliverability before launch
“Before we go live, can you check if the SPF record for our domain sendmail.mycompany.com actually authorizes Mandrill to send on our behalf? I need a yes/no and what the matching mechanism is.”
Audit unexpected third-party sender
“We noticed some email coming from transactions.rivalcorp.com and we suspect they're using Mandrill. Can you check their SPF record to see if Mandrill is authorized and what the record says?”
Validate SPF after DNS change
“We just updated our DNS. Can you verify that the SPF record on outbound.myapp.io still authorizes Mandrill and show me the full SPF record so I can confirm nothing broke?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/mandrill?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to verify Mandrill (Mailchimp Transactional) authorization in a domain's SPF record, not SPF validation in general. Ideal for confirming vendor email integration during onboarding, post-DNS-change audits, or competitive/security intelligence to detect whether a domain is using Mandrill as a sending infrastructure.
Side effects
- Domain has no SPF TXT record — returns no authorization with empty record
- Domain does not exist or is unresolvable — DNS lookup fails
- SPF record exists but does not include Mandrill — returns no with record shown
- DoH (Cloudflare DNS-over-HTTPS) is temporarily unavailable — request times out or errors
- Missing or invalid domain query parameter — returns validation error
