What it returns
Clean email lists before you send. Checks run on DNS and curated lists only, so no mail is sent and no inbox is touched.
Normalized address, user and domain, valid syntax, domain exists, MX records, disposable or temporary address, role-based inbox (info@, sales@, support@), free provider (Gmail, Yahoo, Outlook), a typo suggestion such as gmial.com → gmail.com, and a rating of likely, risky or invalid with the reason.
