Deprecation: #87200 - EmailFinisher "format" option

See forge#87200


The format option of the TYPO3\CMS\Form\Domain\Finishers\EmailFinisher has been marked as deprecated and will be removed in TYPO3 11.0. It is replaced by the new addHtmlPart option which can be used to disable HTML and enforce plaintext-only mails. If set, mails will contain a plaintext and HTML part, otherwise only a plaintext part.

If the format option is used, its value will be automatically migrated to addHtmlPart:

  • format: html becomes addHtmlPart: true
  • format: plaintext becomes addHtmlPart: false
  • a missing format becomes addHtmlPart: true

Opening and saving a form with the form editor once also performs this migration and makes it permanent.


The format option will no longer work in TYPO3 11.0.

Affected Installations

All installations which use EXT:form and its TYPO3\CMS\Form\Domain\Finishers\EmailFinisher.


Replace format: html with addHtmlPart: true.

Replace format: plaintext with addHtmlPart: false.
