We are calling plugin from a declarative pipeline with this code: 

post {
  emailext recipientProviders: [
      [$class: 'RequesterRecipientProvider'],
      [$class: 'DevelopersRecipientProvider']
    ],
    subject: '$DEFAULT_SUBJECT',
    body: '$DEFAULT_CONTENT',
    attachLog: true,
    compressLog: true
}
