我看到了很多创建批量电子邮件的文档和示例，如下面的
message1 = ('That’s your subject #1',
'That’s your message body #1',
'from@yourdjangoapp.com',
['to@yourbestuser1.com', 'to@yourbestuser2.com'])
message2 = ('That’s your subject #2',
'That’s your message body #2',
'from@yourdjangoapp.com',
['to@yourbestuser2.com'])
message3 = ('That’s your subject #3',
'That’s your message body #3',
'from@yourdjangoapp.com',
['to@yourbestuser3.com'])
send_mass_mail((message1, message2, message3), fail_silently=False)
我想向N个从我的查询集返回的用户发送大量电子邮件，并发送相同的消息。我正在使用下面的代码发送大量电子邮件。然而，它非常缓慢，并且想知道是否存在任何有效的方法，或者由于我使用gmail进行测试，它将非常缓慢。
def sendMassPasswordResetEmail(request):
schoolval = user_school.objects.filter(username=request.user.id).values_list('schoolCode',flat=True)[0]
clsval = student_group.objects.filter(schoolCode=schoolval).values_list('classVal_id').distinct()
student = studentclass.objects.all().prefetch_related('student_group_set__username').filter(student_group__classVal__in=clsval).distinct()
addStudentlink = True
#groups = student.values('student_group')
userinschool = User.objects.filter(user_school__schoolCode=schoolval,user_type=1).values('username')
html_content = render_to_string('dashboard/registration_email.html') # render with dynamic value
text_content = strip_tags(html_content) # Strip the html tag. So people ca
for recipient in userinschool:
subject, from_email, to = 'Account Activation xxxxx', 'xxxxxgmail.com.com',recipient.get('username')
print(recipient.get('username'))
msg = EmailMultiAlternatives(subject, text_content, from_email, [to])
msg.attach_alternative(html_content, "text/html")
msg.send()
return render(request,'dashboard/add-student.html',{'students':student, 'addStudentlink':addStudentlink})
由于缺乏知识，我无法为send_mass_email生成动态元组。如有任何帮助，我们将不胜感激。
您应该使用send_mass_mail来执行您想要的操作。
下面是一个如何做到这一点的例子：
messages = ()
for item in items:
messages = messages + ((item.subject, item.message, item.from, [item.to]),)
send_mass_mail(messages, fail_silently=False)
