Frequently Asked Questions
Does this tool check if an email inbox actually exists?
It validates the email's format and syntax. Confirming whether a specific inbox actively exists requires deeper verification, which most free online validators don't perform.
Why would a correctly formatted email still be invalid?
An email can be syntactically correct but still not deliverable — for example, if the domain doesn't exist or the mailbox has been deleted.
Is this validator free to use?
Yes, it's free with no sign-up or usage limits.
