Free Shannon Entropy Bot Username Detector
Measure the randomness of an email username to distinguish human-chosen names from bot-generated strings.
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.
