我已经阅读了this，this和this但没有有效答案。
我试图用html_message与Django一起发送邮件，似乎唯一可行的方法是：
send_mail(
subject=_(u"My news"),
message=message, html_message=html_message,
from_email=u'contact@cogofly.com',
recipient_list=[personne.user.email, ])
（虽然没有BCC而EmailMessage()函数有一个......）。
当我尝试这些线时，我得到：
in send_newsletter, recipient_list=[personne.user.email, ]
AttributeError: 'list' object has no attribute 'encode'
我做错了什么？
这是我的settings.py配置：
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
并且没有其他任何关于邮件发送（我在开发机器上）
我试图按照文档here：
进行操作这里是整个错误堆栈跟踪：

答案 0 :(得分：0)
在您上次更新后，我可以在您的函数...
html_message = [m, u"\n"]
...
中看到此行：
html_message然后使用追加功能将内容添加到html_message = "<strong>Hi there!</strong>"
。因此，您创建了一个列表，即使docs未指定此列表，也应该是HTML格式的字符串：
html_message尝试在send_mail函数中的属性.class中传递字符串。
