Free Email Validator Tool
Check if an email address is valid, deliverable, disposable, or a typo.
Paste an email address to check its syntax, whether the domain can receive mail (MX records), whether it's a disposable/role address, and get a suggestion if it looks like a typo.
Validating emails at signup? The Email Validator API does this in your app, one address or 100 at a time.

Does this send a test email?
No. It checks syntax, MX records, and known disposable domains — no email is sent.
Why is a valid-looking email marked undeliverable?
Usually because the domain has no MX records, so it can't receive mail.
