● Disposable Domain & Fraud Detector
Deep MX telemetry and heuristic verification to detect throwaway burner emails, fake registrations, and abuse vectors.
Why Defending Against Disposable Inboxes Matters
Temporary burner emails cause severe attribution loss, free trial drain, and email deliverability degradation.
Prevent attackers from cycling through limitless temporary inboxes to bypass SaaS account limits, API quotas, and promotion welcome gifts.
Disposable inboxes self-destruct in minutes. Emailing them later causes permanent delivery failures that hurt your domain sending score.
Rather than relying solely on static domain lists, AliasMail resolves mail server hosts to identify multi-tenant disposable relays immediately.
Frequently Asked Questions
Why do users use disposable email addresses?
Disposable email addresses are created by users who want quick, anonymous verification codes without exposing their real inbox, or by abusive actors seeking to exploit free trial quotas, scrape protected content, or commit fraud.
How does the disposable checker catch new burner domains not in public blocklists?
While basic checkers rely purely on static lists of domain names, AliasMail inspects upstream Mail Exchange (MX) hostnames. When burner providers register new rotating domain names pointing to the same mail relays, our MX heuristic immediately flags them.
Should I block all free webmail providers like Gmail and Yahoo?
No. Free webmail providers like Gmail, Outlook, and Yahoo represent legitimate consumer users. The tool distinguishes between genuine consumer webmail and throwaway burner domains so you only filter high-risk ephemeral inboxes.
What is the recommended signup policy for disposable domains?
For SaaS applications and platforms offering free credits, we recommend rejecting signups from domains with risk scores > 70, or enforcing a phone/credit card verification step before granting access.
