Sending an email with Google App Engine

When I first started learning, my application aim was a 'Mass Mailer' with Google App Engine. To start (as a newbie in this domain), I should start with the simplest operation: 'Sending an email using Google App Engine'.

To do this I was lost, I don't know anything about Python. But, how? Take a look around you'll probably find something, return always to the Google App Engine Documentation. Yes, the Send Mail section is available. Let's see it.

Mail Api docs, give you the sample from the overview! Here's what I found

from google.appengine.api import mail

class ConfirmUserSignup(webapp.RequestHandler):
def post(self):
 user_address = self.request.get("email_address")

 if not mail.is_email_valid(user_address):
   # prompt user to enter a valid address

 else:
   confirmation_url = createNewUserConfirmation(self.request)
   sender_address = "support@example.com"
   subject = "Confirm your registration"
   body = """
Thank you for creating an account!  Please confirm your email address by
clicking on the link below:

%s
""" % confirmation_url

   mail.send_mail(sender_address, user_address, subject, body)

Before doing anything! You need to know, that the Send mail function isn't included by default so when running your server, you should add the following command

dev_appserver.py --enable_sendmail

Or your mail won't be sent.
Then create a new Google App Engine Application. If you don't know how, here's a quick startup to create your Google App Engine application in minutes.

Trouble in manipulating this code? No, don't do, you don't need. First we are going simply to test the send_mail function, second we are going to use the Django Frameword and not the Google one.

Here's the code, that I use, simple and clean

from google.appengine.api import mail

print 'Content-Type: text/plain'
print ''
print 'I think the email was sent or going to!'
mail.send_mail("omar.abid2006@gmail.com", "omar.abid2006@gmail.com", "Google Coder", "Googler Coder Welcome")

Here's the list, don't be stupid!

• Your application won't work on your Localhost, so upload it
• To upload it, seek this article
• Run your application 'name.appspot.com'
• Check your inbox
• Don't Send more than 2000, see quotas here

Ok, here's the first goal and it was done, more to come in the future.
