Free Real-Time Disposable & Temporary Email Checker
Instantly test any email address or domain against our edge blocklist, MX host analyzer, and RDAP registry.
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.
