How this service works
Is this email address or domain legitimate? Verdict with reasons: syntax, role address, disposable or free provider, MX / null MX, mail provider, SPF, DMARC, website live, domain age. No mailbox probing.
Output
Returns a structured verdict (legitimate or not) with individual signals: syntax validity, whether it's a role address (e.g. sales@, info@), whether the domain belongs to a disposable or free email provider, MX record presence or null MX, the identified mail provider, SPF record status, DMARC record status, whether the website is live, and the domain's age.
Example use cases
Pre-CRM lead email screening
“Before I add this lead to our CRM, can you check if contact@prospectventures.com is a real business email — I need to know if it's disposable, has valid MX records, and whether the domain is newly registered?”
Fraud detection for marketplace signup
“A new seller just signed up with the email support@quickshopdeal.net — can you tell me if that email and domain look legitimate, including SPF, DMARC, and domain age, so I can decide whether to approve their account?”
Vendor email trust assessment
“We got an invoice from billing@globalparts-supplies.com — can you verify if that email domain is legitimate, check if it has proper mail configuration like SPF and DMARC, and let me know how old the domain is?”
Technical details
Endpoint
GEThttps://stormap.ai/x402/v1/email_domain_check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a multi-signal legitimacy verdict for an email address or domain without sending any probe emails — ideal for trust-and-safety checks, lead qualification, fraud prevention, and CRM hygiene where mailbox probing is undesirable or prohibited. Prefer it over simple syntax validators when you need DNS-level signals (MX, SPF, DMARC) and domain intelligence (age, disposable detection) in a single call.
Side effects
- Invalid or malformed email/domain input returns an error or syntax-fail verdict
- Domain with no DNS records may return null MX with inconclusive verdict
- Very new domains may have limited age data
- Rate limiting if too many requests are made in a short period
- Some privacy-protected domains may obscure age or registration data
