Overview
About Email Validator
Email Validator checks whether an email address follows common format rules and highlights warning signs such as reserved domains, double dots or excessive length. It is useful for forms, lead lists, newsletters and CRM cleanup before importing contact data. This tool checks syntax only, so final deliverability still depends on mailbox existence, DNS and sender reputation.
