The record

Product: Proofy checks email addresses before sending and classifies invalid, risky, disposable, catch-all, and role-based addresses.
Bulk verification: Users can upload CSV or TXT files for bulk verification and download segmented results.
Bulk limits: A bulk file can be up to 65 MB and contain up to 1 million addresses.
Verification signals: Checks include syntax, domain and MX validation, SMTP and mailbox-level signals, disposable detection, catch-all detection, and role-based detection.
API: Proofy offers a REST API for real-time single-address checks and asynchronous batch workflows, returning structured JSON statuses.
Integrations: The API is described for use with forms, apps, CRMs, and automated workflows; bulk results are also available through webhooks.
