Free MX Record & Deliverability Lookup
Inspect the mail exchangers, SPF, and DMARC posture behind any email domain to gauge deliverability.
How to use this tool
Enter an email address in the live tester and run an instant edge scan. The preview shows canonical normalization, disposable detection and a fraud recommendation. The production API adds MX, RDAP, entropy and ASN intelligence in under 85ms.
Why it matters
Fake and disposable emails inflate metrics, drain free-tier credits and enable coupon and referral fraud. Verifying addresses at the point of capture keeps your user base real and your sender reputation healthy.
