Is It Disposable Reviews — Discover what people think of this product.

IsItDisposable detects disposable and throwaway email addresses at signup, before they pollute your database, poison your deliverability, and burn your free tier. A live dataset of 205,000+ domains, MX-validated and refreshed daily. Integrate with a single API call or a drop-in JavaScript snippet. Fails open by design: if we are ever down, your signups keep working. Detects relay services like Apple Hide My Email separately, so you flag them instead of blocking real users. Built for backends and AI agents, with SDKs, webhooks, and batch checking.
