Free Email Validation API — syntax, MX records, and disposable-domain checks

The /email namespace checks syntax, real DNS MX records, and a curated disposable-domain list — three independent checks combined into one is_valid result, not a regex guess.

What's included in /email

Real MX record lookup

Checks whether the domain actually has mail-exchange DNS records — a syntactically valid address can still be undeliverable.

Disposable domain detection

Matched against a curated list of 30+ known temp-mail providers, to keep throwaway addresses out of your signup flow.

Full validation suite

Bulk validation, role-account detection, catch-all detection, and free-provider detection round out the namespace.

MX records in the response

Returns the actual mail-exchange records found, not just a pass/fail boolean.

One key, every namespace

Same key validates emails and phone numbers (see /phone) without a separate vendor relationship.

Frequently asked questions

Does this catch disposable email addresses?

Yes — checked against a curated list of 30+ known temp-mail and disposable domains.

Does it verify the mailbox actually exists?

No — that requires an SMTP handshake which most mail servers block or rate-limit aggressively. This checks syntax, MX records, and disposable-domain status, which catches the large majority of bad signups without false positives.

Is there a bulk endpoint?

Yes — /bulk-validate accepts multiple addresses in one call.
