# E04050 — EmailTemplateNoChangesToSubmit

The draft matches the template's published version, so there is nothing to submit.

- **HTTP status**: `422`
- **Type**: `validation_error`
- **Name**: `EmailTemplateNoChangesToSubmit`

## What to do

Submitting now would just create a version identical to the one that sends already use. If you want to change what sends, edit the draft and submit again. Otherwise there is nothing further to do, because sends already use this content.
