# E04071 — EmailTemplateContactPropertyArchived

The content reads a contact property that has been archived.

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

## What to do

An archived property is not offered to new content, so a version reading it cannot be published. Take the token out of the draft, or unarchive the property to put the key back into use, then submit again. Versions published before it was archived are unaffected and keep sending.

Operations that resolve this:

- [List contact properties](/docs/api/reference/list-contact-properties)
- [Unarchive a contact property](/docs/api/reference/unarchive-contact-property)
