Disposable Email FAQ
What is a disposable email address?
A disposable email address is a temporary address created specifically to receive one-time emails (like registration confirmations) without revealing a real address. Users typically abandon these accounts within minutes to hours. They are created by services like Mailinator, Guerrilla Mail, and 10 Minute Mail.
Why should I block disposable email addresses?
Disposable addresses indicate users who don't want to receive your emails. They inflate your user count with fake signups, skew engagement metrics, and generate hard bounces when the temporary inbox expires. Blocking them at registration protects your sender reputation and keeps your list clean.
How does this checker work?
This tool checks the email domain against a curated database of 10,000+ known disposable email service domains. If the domain matches, the address is flagged as disposable. Note that new disposable services launch constantly — for production-grade blocking, use our email verification API which maintains an up-to-date, real-time database.
Can disposable services use custom domains?
Yes. Some sophisticated disposable services operate under custom or changing domains that are harder to detect. SMTP-level verification (which checks whether a real inbox exists at the moment of verification) catches these where static domain lists cannot. This is one of the verification steps included in StopBouncing's full email verification service.
Need production-grade disposable detection?
Our email verification API detects disposable addresses, checks SMTP deliverability, validates syntax, and screens for catch-all domains — all in one request.
