How this service works
Does the domain's SPF record authorise ionos to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for ionos'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 boolean yes/no indicating whether IONOS is authorized, the specific SPF mechanism that matched (e.g. include:spf.ionos.com or an IP range), and the complete raw SPF TXT record retrieved from the domain's DNS via Cloudflare DoH.
Example use cases
Verify IONOS onboarding for new domain
“We just set up IONOS as our email provider for acmecorp.com — can you confirm the SPF record actually authorizes IONOS to send mail for us?”
Audit unexpected IONOS sender authorization
“I didn't intentionally add IONOS to my SPF setup for clientsite.io — can you check if their servers are actually authorized in the SPF record so I can figure out if something was misconfigured?”
Pre-launch deliverability check
“Before we go live with our IONOS email campaign for brandlaunch.com, can you verify that the SPF record properly authorizes IONOS as a sender so we don't have deliverability issues?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/spf-authorizes/ionos?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to confirm whether IONOS is authorized as an email sender for a domain via SPF. It is purpose-built for IONOS vendor integration checks, unlike generic SPF parsers that require you to interpret raw records yourself. Ideal for onboarding validation, deliverability audits, or detecting unauthorized IONOS sender configurations.
Side effects
- Domain has no SPF TXT record — returns no authorization found
- Domain does not exist or DNS lookup fails — returns DNS resolution error
- Malformed SPF record that cannot be parsed — may return unexpected result
- IONOS is not present in the SPF record — returns no with full record for inspection
- Rate limiting or payment failure — returns 402 Payment Required
