Email-Validation API

Overview This Email Validator API goes beyond basic syntax checking. Most email validators only check if the format looks correct. This API actually connects to the mail server via SMTP and confirms the address exists — catching fake signups, disposable addresses, and dead mailboxes that simple checks completely miss. Imagine someone signs up on your website with a throwaway email. They pollute your database and never become a real user. This API catches those bad emails at the point of entry — before they ever reach your system. Unlike other validators that always run every check regardless of what you need, this API lets you specify exactly which checks to run using the fields parameter. Only the checks you request actually execute — so a disposable-only check responds instantly, while a full SMTP probe only fires when you explicitly ask for it. You get responses as fast as the check you need, nothing more. What Gets Checked — 11 Fields Field What It Does syntax Checks email format a
