    You can use it as django send_mail function

    Example:
    send_mail_sync.delay(subject, message, from_mail, recipient_list, fail_silently=False, html_message=None)

    Also you can ignore the from_mail, unlike django send_mail, from_email is not a require args:

    Example:
    send_mail_sync.delay(subject, message, recipient_list, fail_silently=False, html_message=None)
    """
    if len(args) == 3:
        args = list(args)
        args[0] = settings.EMAIL_SUBJECT_PREFIX + args[0]
        args.insert(2, settings.EMAIL_HOST_USER)
        args = tuple(args)

    send_mail(*args, **kwargs)
