Django – Sending E-mails

Django – Sending E-mails

Django comes with a light engine that is ready and simple to use to send emails. Similar to Python, you just need to import a smtplib. You just need to import django.core.mail in Django. Edit the project settings.py file to start sending emails and set  all the following options:

• EMAIL_HOST – server with smtp.
• EMAIL_HOST_USER – smtp server login key.
• EMAIL_HOST_PASSWORD ? Password credential for the smtp server.
• EMAIL_PORT – server port smtp.
• EMAIL_USE_TLS or _SSL – if it is secure connection then set True.

Simple E-mail Sending

To submit a simple e-mail, let's create it a "simpleEmail" view.

from django.core.mail import send_mail
 from django.http import HttpResponse
 def simpleEmail(request,emailto):
    res = send_mail("hello deepak", "comment tu ?", "deepak@gmail.com", [emailto])
    return HttpResponse('%s'%res) 

Description of the parameter s of send mail-

• subject – In this we write subject about e-mail.
• message –In this we write body for e-mail .
• 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 ?In settings.py user password will not set.
• connection – Backend of e-mail.
• html_message –It is new in Django 1.7 if present the e-mail will be multipart.

Creating URL to access a 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'),) 

Sending Multiple Mails with send_mass_mail.

The process returns the number of messages sent successfully. This is the same as send mail but takes an extra parameter; datatuple, our view of sendMassEmail will be ?

from django.core.mail import send_mass_mail
 from django.http import HttpResponse 
 def sendMassEmail(request,emailto):
    message1 = ('subject 1', 'message 1', 'deepak@gmail.com', [first email]) 
    message2 = ('subject 2', 'message 2', ' deepak@gmail.com', [second email])
    res = send_mass_mail((msg1, msg2), fail_silently = False)
    return HttpResponse('%s'%res) 

Creating URL to access a view.

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'),) 

send_mass_mail details parameters are –

• datatuples ? A tuple where element like (subject, message, from_email, recipent_list)
• fail_silently ? Boolean, in case of error, if false send_mail raises an exception.
• auth_user – login of user will not set in settings.py.
• auth_password – password of user will not set in setting.py .
• connection ? E-mail backend.

Note ? In the above example we are using Python smtp debuggingserver, that can launch using –

$python -m smtpd -n -c DebuggingServer localhost:1025

This means all your sent e-mails will be printed on stdout , and the dummy server is running on localhost:1025.
