Email cannot receive mail

Error code​

{
  "code": "email_undeliverable",
  "docUrl": "https://doc.mor.payments.ai/errors/email-undeliverable"
}

HTTP status​

400

Cause​

The contact email was syntactically valid, but the payment provider rejected it because the mailbox cannot receive mail (no MX, disposable, or otherwise unverifiable).

This is not the same as “this email is already registered.” Duplicate-email failures stay generic (company_provisioning_failed) and do not use this code.

How to fix​

Retry onboarding or create_merchant_account with a different email that accepts incoming mail.

See the API Reference for the operation that returned this error.
