What the free email verifier checks
This free email verifier tool runs these checks on every address:
- Syntax: the address is well formed.
- Domain: the domain has MX records, so it can receive mail.
- Mailbox: the mail server accepts the recipient during an SMTP handshake. No email is sent.
- Temporary email: the domain belongs to a disposable email provider.
- Catch-all: the domain accepts mail for any address, so the mailbox can't be confirmed.
- Blacklist checks: the domain is on the Spamhaus Domain Block List or our list of common typo domains (such as gmai.com), or the part before the @ is abuse, spam, root or postmaster.
- Score: 0 means the address will bounce, 10 means it's fully verified.
Limits of a free check
You get 5 free checks per hour. Each check asks you to pass an hCaptcha first, and the result comes back in real time.
Some results are uncertain by nature. A catch-all domain accepts every address, so the mailbox check can't tell real inboxes from made-up ones. If a check takes longer than 10 seconds, you get a neutral score of 6 and the syntax, domain and mailbox rows show n/a. A valid result also doesn't guarantee delivery.
