Email Validation

Utilities
POST /api/v1/email/validate Bearer

Email Validation API — checks whether an address can actually receive mail, without sending one. result is a single verdict you can switch on: valid, invalid, invalid_syntax, risky or unknown, with is_valid as the boolean shortcut and reason explaining a rejection. The domain block classifies the receiving domain — is_disposable (throwaway inbox), is_free (consumer webmail), is_spam, is_catch_all and is_valid — while the account block flags role addresses (info@, support@) and full mailboxes. Resolved mx_records are returned too. Built for signup gating, list hygiene and bounce-rate reduction.

What Email Validation Is Used For

Signup form validation

Check an address can actually receive mail before you create the account, without sending anything.

Disposable address blocking

Reject throwaway inboxes at registration using the is_disposable classification.

Deliverability protection

Keep invalid addresses out of your list so your sender reputation is not damaged.

Risk-aware routing

Switch on a single verdict of valid, invalid, invalid_syntax, risky or unknown and handle each differently.
