Free Email Validator

About this Email Validator

Free, fast, no-login email validity checker. Paste an email address and we’ll check syntax, domain & MX records, flag disposable providers and typos, and—if enabled—run a safe SMTP deep check without sending email. You can copy the results and validate more addresses in seconds. Want to verify a whole list? Try our Email list validation tool.

How to use the Validator

• Paste the email address.
• (Optional) select the Deep check (SMTP) for a server handshake.
• Click Validate. Results appear in the table.
• Copy results to share or clean your list.

What we check (and why it matters)

• Syntax – Confirms correct proper email format (name@domain).
• Domain & DNS – Verifies the domain exists and resolves.
• MX records – Verifies the domain can receive mail.
• SMTP handshake (optional) – Checks the mail server accepts the recipient (no message sent).
• Disposable domains – Flags temporary inbox providers that can hurt deliverability lists.
• Common typos – Catches mistakes and suggests fixes (e.g., gmial.com → gmail.com).

What the results mean

• Valid – Overall status for this address.
• No Typo – No common domain or format mistakes detected.
• Not Disposable – Not from a temporary email service.
• Has MX – Domain publishes MX records (can receive mail).
• SMTP Passed – Server accepted the address during handshake (only when deep check is on).
• Fail Reason – Why validation failed or why it’s risky (e.g., no MX, invalid syntax, disposable, catch-all).

Tips for higher deliverability

• Use double opt-in and remove hard bounces.
• Set up SPF, DKIM, DMARC for your sending domain.
• Be careful with catch-all and role-based addresses (support@, info@).
• Keep lists fresh; validate before big sends.

Why use this Email Validator

• Deep check (SMTP) for higher confidence.
• Clear reasons for fails, so you can fix issues fast.
• Free and online tool – you don't need to sign up to any service.
• Simple to use validator with one clear input and instant results.

FAQ

• What is an email validator?
  An email validator is a tool that checks whether an email address is correctly formatted, belongs to a live domain with MX records, and—optionally—whether the destination mail server accepts the recipient, all without sending an email.
• How do I check if an email is valid?
  Run it through this email validity checker. We test syntax, domain/DNS, MX records, and optionally perform an SMTP handshake to see if the server will accept the address—without sending a message.
• Do you send a test email?
  No. The SMTP deep check only handshakes the server. We never send a message during validation.
• What is a catch-all domain?
  A domain configured to accept any address, valid or not (e.g., [email protected] returns “OK”). Some will still bounce later — treat as higher risk.
• Why can a “valid” email still bounce?
  Full mailbox, greylisting, spam rules, or temporary server issues. Try later and use double opt-in.
• Can I bulk-validate a list of emails?
  Yes—use our Email list validation tool to validate large lists in one go. It runs the same checks (syntax, domain/MX, disposable, typos) and returns validated results fast.
