Email Validator

Paste an email address and get an instant format check, followed by an MX-record lookup that confirms the domain can actually receive mail, which catches a typo like `gmial.com` that would otherwise pass basic format validation cleanly. It also flags addresses on a known list of disposable-email domains and separately flags common role-based addresses like `admin@` or `noreply@`, both useful signals for signup fraud prevention even though neither is a hard block on its own. None of this confirms the specific mailbox actually exists: real mailbox verification requires probing the mail server directly over SMTP, which is unreliable and frequently blocked by providers, so an MX record passing is the practical ceiling of what can be checked this way. For validating a large batch of addresses rather than one at a time, the REST API or SDK is the better fit.
