#1 Email Verification Tool to verify the existence and legitimacy of email addresses

About our email validation tool

Email Verification Lookup performs various email address checks for syntax errors, free and disposable addresses, mail server and mailbox existence, and more.

• Identify free email service providers

  Email Verification Lookup checks if an address was created using a free email service. Such addresses are unlikely to be used in a business environment.

• Automatically detect disposable email addresses

  Spot abusive users who attempt to sign up with disposable email addresses from Mailinator, 10MinuteMail, GuerrillaMail, or other 2,000 known disposable email service providers.

• Avoid syntax errors

  Easily detect invalid email addresses that do not follow prescribed Internet Engineering Task Force (IETF) formats with Email Verification Lookup’s complete syntactic email validation engine.

• Verify the existence of an address’s mail server

  Every valid email address should have a corresponding mail server with its own DNS MX record. Email Verification Lookup can check if an email address has such records and therefore exists.

• Ensure mailbox existence

  Email Verification Lookup’s email-sending emulation and SMTP connection techniques let you verify if an address is able to receive emails.

• Notice catch-all email addresses

  Email Verification Lookup detects catch-all email addresses that are not assigned to a specific individual and may result in hard bounces.
