# sender_domain_not_verified

**HTTP status:** 422 (Unprocessable)

**Title:** Sender domain not verified

## Cause

The sender address must belong to a verified domain of the organization. Check GET /v2/email/domains.

## How to fix it

Use a sender address on a verified domain, or verify the domain first.

Call the endpoint named below first, then send the request again.

Endpoint: `GET /v2/email/domains`

Every error carries `requestId` and the `Request-Id` header. Send it when you write to support.
