How Proofy Email Verification Software Works

Proofy is email verification software designed for teams that need clean, accurate contact data before every campaign. The verification process runs through multiple checkpoints to ensure maximum accuracy.

First, syntax validation catches formatting errors and typos in email addresses. Next, domain-level checks confirm that the DNS and MX records are properly configured and the domain is active. Finally, mailbox-level SMTP verification determines whether each individual email address exists and can receive messages.

Every verification returns a detailed status - valid, invalid, risky, catch-all, or unknown - giving you full control over which contacts to keep and which to remove. Proofy's email verifier software supports CSV and TXT uploads for list processing, making it easy to verify email lists of any size.

Whether you are a solo marketer verifying a small list or an enterprise team processing millions of records, Proofy's email validation software scales with your needs. Credits never expire, and results are available within minutes.
