## About

Is It Disposable detects and blocks disposable email addresses at signup, protecting your sender reputation and data quality.

The service offers DNS-level detection with no SMTP probing, a clean REST API, and a drop-in JavaScript snippet. Return verdicts that map to your policy—allow, warn, or block signups with disposable emails. Fails open for reliability.

Ideal for marketing teams, SaaS platforms, and services concerned with signup quality, email deliverability, and user verification.
