Free Email Verifier
Check Any Email Address — Free & Instant
FareOf validates syntax, MX records, and SMTP deliverability without sending a single message. No account required.
What Is Email Verification?
Email verification is the process of confirming that an email address is real, active, and capable of receiving messages — without actually sending one. It combines several checks:
- Syntax check — confirms the address follows RFC 5322 formatting rules.
- Domain/MX check — queries DNS to confirm the domain has mail exchange records.
- SMTP handshake — connects to the mail server and asks whether the mailbox exists, without sending a message.
- Disposable detection — cross-references known temporary email providers.
- Catch-all flag — identifies domains that accept any address, masking true deliverability.
Together these signals give you a reliable deliverability score before you hit send, protecting your sender reputation and improving open rates.

Frequently Asked Questions
Is this email verifier really free?
Yes. You can verify individual email addresses for free with no account required. Bulk verification and API access require a FareOf plan.
What does "valid" mean in the results?
A valid result means the email passed syntax checks, has working MX records, and our SMTP handshake confirmed the mailbox exists.
What is a catch-all email?
A catch-all domain accepts mail for any address at that domain, so we cannot confirm whether a specific mailbox exists. These are flagged as risky.
Will you send an email to verify the address?
No. FareOf uses DNS and SMTP-level checks without sending any message to the target address.
How accurate is the verification?
FareOf achieves over 98% accuracy for addresses that are not protected by catch-all or greylisting configurations.
What is a hard bounce vs a soft bounce?
A hard bounce means the address is permanently invalid. A soft bounce means delivery failed temporarily — full mailbox or server issues.
