Is It Disposable

Is It Disposable is a lightweight disposable email detection service built for teams that care about signup quality and sender reputation. Instead of letting throwaway inboxes pollute your user base, skew your metrics, and drag down your email deliverability, Is It Disposable checks addresses at the form level using DNS-based detection — no slow, unreliable SMTP probing — and returns a fast, trustworthy verdict you can act on before an account is ever created. Integration is intentionally boring: a drop-in JavaScript snippet for frontend forms, or a clean REST API you can hit from any backend in a few lines of code. The result is a cleaner user list, more accurate activation and retention numbers, fewer bounces hurting your domain reputation, and less time wasted chasing ghost accounts. A live demo and a free tier let you validate it against your own signup patterns before committing to a paid plan.
