Email Verifier

Check if an email address is valid instantly. Verify format, domain, and MX records — no signup required.

Why Verify Emails?

Sending emails to invalid addresses damages your sender reputation and wastes resources. High bounce rates can get your domain blacklisted by email providers like Gmail and Outlook. Verifying emails before sending ensures:

  • Higher deliverability — your emails reach real inboxes
  • Lower bounce rates — stay under the 2% threshold
  • Protected domain reputation — avoid spam filters and blacklists
  • Better ROI — focus outreach on valid contacts only

How Our Email Verifier Works

Our free email verification tool performs three checks:

  1. Syntax validation — checks if the email format is correct (e.g., user@domain.com)
  2. Domain verification — confirms the domain exists and is active
  3. MX record lookup — verifies the domain can receive emails

This free tool is perfect for checking individual emails. If you need to verify thousands of emails from your lead lists, LeadScraper Pro includes built-in email finding and verification for leads extracted from Google Maps.

Frequently Asked Questions

How does email verification work?

Email verification checks three things: format validation (is the email syntactically correct), domain check (does the domain exist and have MX records), and mailbox verification (can the mailbox receive emails). Our free tool checks format and domain/MX records instantly.

Is this email verifier really free?

Yes, completely free with no signup required. You can verify individual email addresses unlimited times. For bulk verification of lead lists, check out LeadScraper Pro plans.

Why should I verify emails before sending?

Sending to invalid emails hurts your sender reputation, increases bounce rates, and can get your domain blacklisted. Verifying emails first ensures higher deliverability and protects your domain reputation.

What's the difference between format check and MX check?

Format check validates the email syntax (user@domain.com). MX check goes deeper — it queries the domain's DNS records to confirm the domain has mail servers configured to receive emails.
