Proofy review
A practical choice for large-file verification without a subscription commitment.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Proofy is an email verification service for marketers, developers, and teams validating individual addresses or cleaning large lists. It supports CSV and TXT uploads, REST API workflows, batch processing, real-time form validation through a JavaScript widget, and downloadable verification exports. Verification covers syntax, domains, MX records, SMTP responses, disposable and temporary addresses, catch-all and accept-all behavior, and role-based addresses. It can also classify results as valid, invalid, risky, unknown, disposable, catch-all, or role-based without sending messages to the addresses being checked.
The main pricing entry point is the Trial plan: a $5 one-time package with 5,000 verifier checks for new users and no subscription required. The published plans also describe subscription options, while monthly package pricing is not published. A credit rollover is included in the category specifications. This structure suits teams that want to start with a defined one-time allowance, but buyers seeking a free plan or clearly stated monthly costs should consider alternatives.
Proofy's strongest fit is large-file and multi-channel verification. A single file can contain up to 1 million addresses, while the REST API supports single, batch, and file verification. The JavaScript widget adds real-time checks to forms, and customizable exports help tailor downloaded results. These capabilities make Proofy a practical choice for teams combining list cleaning with application or workflow validation. It is less suitable for buyers prioritizing a free entry tier or documented integrations, since the available platform options are web and API and integration data is not provided.
