This is working well on my Jenkins (current ver 2.164.2 and emailext) with declarative pipeline:

pipeline {
...

environment {
        EMAIL_TO = 'someone@host.com'
    }
post {
        failure {
            emailext body: 'Check console output at $BUILD_URL to view the results. \n\n ${CHANGES} \n\n -------------------------------------------------- \n${BUILD_LOG, maxLines=100, escapeHtml=false}', 
                    to: "${EMAIL_TO}", 
                    subject: 'Build failed in Jenkins: $PROJECT_NAME - #$BUILD_NUMBER'
        }
        unstable {
            emailext body: 'Check console output at $BUILD_URL to view the results. \n\n ${CHANGES} \n\n -------------------------------------------------- \n${BUILD_LOG, maxLines=100, escapeHtml=false}', 
                    to: "${EMAIL_TO}", 
                    subject: 'Unstable build in Jenkins: $PROJECT_NAME - #$BUILD_NUMBER'
        }
        changed {
            emailext body: 'Check console output at $BUILD_URL to view the results.', 
                    to: "${EMAIL_TO}", 
                    subject: 'Jenkins build is back to normal: $PROJECT_NAME - #$BUILD_NUMBER'
        }
    }
}

You can control email for failed build or changed status. Also I've put build log to the email body
