EDIT: For airflow to send an email on failure, there are a couple things that need to be set on your task, email_on_failure and email.

t1 = PythonOperator(task_id='throw_error_and_email',
                    python_callable=throw_error,
                    provide_context=True,
                    email_on_failure=True,
                    email='your.email@whatever.com',
                    dag=dag)
