Disposable email checker

Check an email address or domain against the current temporary-provider classification.

What the checker does

The checker extracts the domain and compares it with the same maintained disposable-provider data used by emailverifier.dev domain reports. It also distinguishes mainstream free mailbox providers from disposable services.

A “not listed” result means only that the domain has no current disposable classification. New providers and rotating domains can appear, and a domain lookup cannot confirm one mailbox. Use the verification API when the signup decision needs complete-address evidence.
