Introduction

Django comes with a ready and easy-to-use light engine to send e-mail. Similar to Python you just need an import of smtplib. In Django you just need to import django.core.mail.

To Start sending an E-Mail: Edit the setting.py file

Procedures to Send Simple E-mail

Let's create a "sendSimpleEmail" view to send a simple e-mail.

from django.shortcuts import render

from .forms import EmailForm

from django.core.mail import send_mail

from django.conf import settings

def sendSimpleEmail(request):

# create a variable to keep track of the form

messageSent = False

# check if form has been submitted

ifrequest.method == 'POST':

form = EmailForm(request.POST)

# check if data from the form is clean

ifform.is_valid():

cd = form.cleaned_data

subject = "Sending an email with Django"

message = cd['message']

# send the email to the recipent

send_mail(subject, message,

settings.DEFAULT_FROM_EMAIL, [cd['recipient']])

# set the variable initially created to True

messageSent = True

else:

form = EmailForm()

returnrender(request, 'index.html', {

'form': form,

'messageSent': messageSent,

})

The details of the parameters of send_mail −

subject − E-mail subject.
message − E-mail body.
from_email − E-mail from.
recipient_list − List of receivers’ e-mail address.
fail_silently − Bool, if false send_mail will raise an exception in case of error.
auth_user − User login if not set in settings.py.
auth_password − User password if not set in settings.py.
connection − E-mail backend.
html_message − The e-mail will be multipart/alternative.

Let's create a URL to access our view.


from django.conf.urls import patterns, url

urlpatterns = paterns('myapp.views', url(r'^simpleemail/(?P<emailto>[\w.%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4})/', 
'sendSimpleEmail' , name = 'sendSimpleEmail'),)

So when accessing /myapp/simpleemail/saisrivatsau1998@gmail.com, The output the page shows with the count of mail sent.

Then we can see the output with One messages were sent successfully.

Sending Multiple Mails with send_mass_mail

The method returns the number of messages successfully delivered. This is same as send_mail but takes an extra parameter; data tuple, our sendMassEmail view will then be −

from django.core.mail import send_mass_mail
from django.http import HttpResponse

def sendMassEmail(request,emailto):
   msg1 = ('subject 1', 'message 1', 'polo@polo.com', [emailto1])
   msg2 = ('subject 2', 'message 2', 'polo@polo.com', [emailto2])
   res = send_mass_mail((msg1, msg2), fail_silently = False)
   return HttpResponse('%s'%res)

Let's create a URL to access our views:-

from django.conf.urls import patterns, url

urlpatterns = paterns('myapp.views', url(r'^massEmail/(?P<emailto1>
   [\w.%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4})/(?P<emailto2>
   [\w.%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4})', 'sendMassEmail' , name = 'sendMassEmail'),)

So when accessing /myapp/simpleemail/saisrivatsau1998@gmail.com, The output the page shows with the count of mail sent.

send_mass_mail parameters details are −

data tuples − A tuple where each element is like (subject, message, from_email, recipient_list).
fail_silently − Bool, if false send_mail will raise an exception in case of error.
auth_user − User login if not set in settings.py.
auth_password − User password if not set in settings.py.
connection − E-mail backend.

Then we can see the output with two messages were sent successfully.
