Detect disposable emails, role-based addresses, and validate deliverability
GET /v1/email/check?email=user@example.com
Check multiple emails at once (one per line, max 100)
Disposable (or temporary/burner) emails are addresses from services like 10minutemail, guerrillamail, or tempmail that self-destruct after a short period. They're often used to bypass email verification, spam forms, or create fake accounts.
Disposable emails lead to low-quality signups, fake accounts, and abuse. Users with disposable emails have near-zero engagement and often don't complete verification. Blocking them improves your user quality and reduces fraud.
We check: (1) Disposable domain matching against 186k+ domains from 5 sources, (2) Role-based address detection (admin@, support@), (3) Free provider detection (gmail, yahoo), (4) MX record validation, and (5) DNS blacklist (DNSBL) status.
Our disposable domain database is updated daily.
