我嘗試向多個收件人發送電子郵件，但我做錯了。我正在使用 for 回圈從用戶那里獲取電子郵件地址。如果我列印這些電子郵件，它們的格式是這樣的：'[email protected]'而且我有不止一個。但是，如果我嘗試向他們發送電子郵件，則只有一個用戶會收到它。
如果重繪 urls.py 中的 html，它每次都會發送郵件。

firstday = datetime.date.today().replace(day=1)
subject='hello'
message='how are you?'

recipient_list = p.email,
print(recipient_list)
if (today == firstday):
messages = [(subject, message, from_email, [recipient]) for recipient in recipient_list]
send_mass_mail(messages)
print('Successfully sent')
else:
print('Not sent')
return render(request, 'performance/emails.html')
網址.py
app_name = 'email'
urlpatterns = [

獲取要向其發送電子郵件的人員串列
https://docs.djangoproject.com/en/4.0/topics/db/sql/
recipient_list = Project.objects.raw(...)
如果您的訊息沒有改變，您也可以使用
send_mail(
subject,
message,
from_email,
[r.email for r in recipient_list],
)
如果您想使用群發郵件，因為它更有效 https://docs.djangoproject.com/en/4.0/topics/email/
messages = [(subject, message, from_email, [r.email]) for r in recipient_list]
send_mass_mail(messages)
