Disposable email address detection via a drop-in JavaScript snippet and a REST API.
Visit isitdisposable.com →DocsPricing
A service that checks email addresses or domains at signup and returns a disposable verdict plus opt-in signals (deliverability, relay, public provider, role account, spam risk, masked routing), each mapped to an allow, warn, or block action by the customer's own policy. Detection is DNS-level only with no SMTP probing, and the API fails open when over quota or unavailable. Includes a dashboard with enforcement policy, allow/block lists, usage analytics, webhooks, and team seats.
