电子邮件未从管理面板发送

Question

我正在尝试让Django管理员向站点的用户发送电子邮件。但是，我无法将电子邮件发送到用户的电子邮件收件箱。似乎没有任何编译问题，但收件箱中什么也没有。到底出了什么问题？我也确保在Django中正确设置电子邮件。这是我的代码：

views.py

def sendUserEmails(request):
    form = SendEmailForm(request.POST)
    print("going here")
    if form.is_valid():
        subject = form.cleaned_data['subject']
        message = form.cleaned_data['message']
        users = form.cleaned_data['users']

        for user in users:
            send_mail(subject, message, from_email, user.email, fail_silently = True)

        user_message = '{0} users emailed successfully!'.format(form.cleaned_data['users'].count())
        messages.success(self.request, user_message)

    return render(request, 'admin/send_email.html', {'form': form})

forms.py

class SendEmailForm(forms.Form):
    subject = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Subject'}))
    message = forms.CharField(widget=forms.Textarea)
    users = forms.ModelMultipleChoiceField(label = "To", queryset = Account.objects.all(), widget = forms.SelectMultiple())

admin.py中的电子邮件功能

def send_email(self, request, queryset):
    form = SendEmailForm(initial = {'users' : queryset})
    return render(request, 'admin/send_email.html', {'form': form})

urls.py

path('admin/solutions/account/', views.sendUserEmails, name='email'),

我尝试调试没有成功。请帮忙。
