Proofy
Email verification service that checks addresses before sending to reduce bounces and keep
Proofy is an email verification service that checks addresses before they are added to campaigns, database imports, or CRM records. It evaluates syntax, domain, MX, and SMTP signals alongside disposable, catch-all, role-based, and risk checks to classify addresses as valid, invalid, risky, or unknown, without sending any message to the address being checked.
Verification is available through three workflows: a free single-address checker, bulk verification via CSV or TXT upload with segmented results, and a REST API for real-time validation in forms, apps, and automated workflows. The API offering includes Single Verification, Bulk, and Batch endpoints, a JavaScript Widget, and webhook support. Additional signals include mailbox-full detection, ISP and SMTP provider identification, and duplicate removal.
Proofy is aimed at teams managing sending lists and contact data quality. Pricing is credit-based, with one credit per verified email and credits that do not expire; duplicate and unknown results are not charged. Plans are available as pay-as-you-go or subscription, with a trial package for new users, tiered volume pricing, and custom arrangements for enterprise clients.
