Sending Django Emails via AWS SES

Boto is the de facto standard for working with the AWS API from Python. Unfortunately their SES implementation only sends text or html emails, not both. You need to drop down to their send_raw_email method to send a multi-part email.

Using this Gist as a guideline, here’s an implementation of sending a multi-part email via a library class:

amazonses.py

	from email.utils import COMMASPACE
	from email.mime.multipart import MIMEMultipart
	from email.mime.text import MIMEText
	from boto.ses import SESConnection
	from django.conf import settings


	class SESMessage(object):

	def __init__(self, source, to_addresses, subject, **kw):
	self.ses = SESConnection(settings.AWS_ACCESS_KEY, settings.AWS_SECRET_KEY)

	self._source = source
	self._to_addresses = to_addresses
	self._cc_addresses = None
	self._bcc_addresses = None

	self.subject = subject
	self.text = None
	self.html = None
	self.attachments = []

	def send(self):
	if not self.ses:
	raise Exception, 'No connection found'

	if (self.text and not self.html and not self.attachments) or\
	(self.html and not self.text and not self.attachments):
	return self.ses.send_email(self._source, self.subject,
	self.text or self.html,
	self._to_addresses, self._cc_addresses,
	self._bcc_addresses,
	format='text' if self.text else 'html')
	else:
	if not self.attachments:
	message = MIMEMultipart('alternative')

	message['Subject'] = self.subject
	message['From'] = self._source
	if isinstance(self._to_addresses, (list, tuple)):
	message['To'] = COMMASPACE.join(self._to_addresses)
	else:
	message['To'] = self._to_addresses

	message.attach(MIMEText(self.text, 'plain'))
	message.attach(MIMEText(self.html, 'html'))
	else:
	raise NotImplementedError, 'Attachments are not currently supported.'

	return self.ses.send_raw_email(message.as_string(), source=self._source,
	destinations=self._to_addresses)

You’ll also need to add your AWS access key and secret to your settings file:

settings.py

	# Amazon AWS
	AWS_ACCESS_KEY = 'AKIA……..'
	AWS_SECRET_KEY = 'w71v……..'

You can then use the class like this:

	from app.lib.amazonses import SESMessage


	def contact(request):

	if request.method == 'POST':

	form = ContactForm(request.POST)

	if form.is_valid():

	# grab the form data
	name = form.cleaned_data['name']
	email = form.cleaned_data['email']
	subject = form.cleaned_data['subject']
	body = form.cleaned_data['body']
	recipient = 'recipient@site.com'

	# render the template with the submitted data
	rendered = render_to_string('email/contact.html', {'name': name, 'email': email, 'subject': subject, 'body': body})

	# create the message and send the email
	# the from address must be a verified sender in SES
	msg = SESMessage('valid_sending_address@site.com', recipient, subject)
	msg.text = rendered
	msg.html = rendered + ' html'
	msg.send()

	messages.add_message(request, messages.INFO, 'Your contact enquiry was successfully sent. Thank you!')

	return HttpResponseRedirect(reverse('contact'))

	else:

	form = ContactForm()

	return render(request, 'contact.html', {'form': form})
