Proofy is an email verification service that checks email addresses before sending, identifying invalid, risky, disposable, catch-all, and role-based addresses. It offers a web dashboard for bulk list verification, a single free email checker, and a REST API (single, batch, and file endpoints) plus a JavaScript widget for real-time validation at signup or checkout. Verification uses syntax, domain/MX, and SMTP-handshake checks without sending an actual email, aiming to reduce bounce rates and protect sender reputation.
