Validate Email DNS API (Including Disposable Emails)

What it does

Email Validator checks whether an email address is valid and deliverable. Send an email address in the request body, and you get back a boolean data value indicating whether it passes verification.

Use disposable_checks when you want to reject known disposable domains before MX verification. It defaults to true, so you can catch throwaway addresses without adding extra logic in your app. The response stays simple: true or false.

This is useful anywhere you need to screen signups, clean lead lists, or reduce bounce rates before sending messages. Add it to registration flows, CRM imports, newsletter subscriptions, or contact forms when you want a fast yes-or-no check on an address.
