Free email tools
Quick answers about a domain or an address, free and without signup. For a complete check of an address (syntax, domain, MX and mailbox), use the free email checker.
MX record lookup
Enter a domain to see its MX records: the mail servers that receive its email, in the order senders try them, and the email provider behind them.
Disposable email checker
Enter an email address or a domain to find out whether it belongs to a temporary (disposable) inbox service.
Catch-all email domain test
Enter a domain to find out whether its mail server accepts email for any address (catch-all), which means individual mailboxes on it cannot be confirmed.
Each tool includes 5 free checks every 2 hours.
