Free Email Verifier
Instantly verify if any email address is real and deliverable.
What is Email Verification?
Email verification is the process of checking whether an email address is real, valid, and able to receive messages. Our free email verifier performs multiple checks including syntax validation, domain verification, MX record lookup, and SMTP handshake to determine if an email address is deliverable.
Understanding results
Valid
The email address exists and is accepting mail. Safe to send.
Risky
The result is uncertain. Common with catch-all domains or temporary issues. Requires deep verification.
Invalid
The email address doesn't exist or is not accepting mail. Do not send.
How it works
Syntax Check
Validates the email format follows RFC 5322 standards
Domain Verification
Confirms the domain exists and is configured for email
MX Record Lookup
Checks for valid mail exchange records
SMTP Handshake
Connects to the mail server to verify the mailbox exists
Catch-All Detection
Identifies domains that accept all emails regardless of mailbox
Why verify email addresses?
