-- **_subject**: *Optional*. The email subject.
-- **_info**: *Optional*. This text will be included in the email body before the values. Useful for providing some context in the email body.
-- **_attachment**: *Optional*. A file can be attached to the email form using this for the name of an `<input type="file"/>`. When sending attachments do not forget to include `enctype="multipart/form-data"` in your form tag.
-- **_next**: *Optional*. A URL to redirect the user once the form was submited succesfully.
-- **_fake**: *For testing*. If `true`, the email will not be sent and instead a JSON paylod will be shown. Useful when testing the form with a REST client.
