TypeError at /contact/ - аргумент "to" должен быть списком или кортежем - Django

Я хочу отправить данные электронной почты контактной формы на почтовый идентификатор домена, но при заполнении всех полей контактной формы и ее отправке я получаю ошибку -

Значение исключения: аргумент "to" должен быть списком или кортежем.

Пожалуйста, подскажите, как решить эту проблему.

email_body = '{name}\n\n    {phone} - {email} - {address} \n\n {message}'.format(**form_data))

send_mail(
