Email Verifier

Verify email addresses instantly. Check if emails are real, detect disposable addresses, and solve email delivery problems.

Why Your Emails Bounce: Common Problems We Solve

  • Emails sent to non-existent addresses get marked as bounces
  • Sending to disposable emails hurts your sender reputation
  • Role accounts (info@, support@) may not reach the right person
  • Typoos in domain names cause silent delivery failures
  • Missing MX records mean the domain can't receive any email

Verifying email...

What We Check

SMTP Verification

We connect to the mail server to verify if the mailbox actually exists and can receive messages.

MX Record Check

We verify if the domain has proper mail server records configured to receive emails.

Disposable Detection

We identify temporary/disposable email services that are often used to bypass sign-ups.

Role Account Detection

We detect role-based emails (support@, info@) that may not reach a specific person.

Spelling Suggestions

If you typo'd the domain, we'll suggest the correct one (like Gmail → google.com).

Quality Score

How Email Verification Works

1 Format Check - First we verify the email has valid syntax (user@domain.com format)
2 MX Lookup - We check if the domain has mail servers configured to receive email
3 SMTP Connect - We connect to the mail server and ask if this mailbox exists (without sending an email)
4 Risk Assessment - We check for disposable domains, role accounts, and other risk factors

Is my data private when I use Email Verifier?

Does Email Verifier work without an internet connection?
