send_mass_emails with EmailMultiAlternatives

Question

I try to build a newsletter application and want to send 50 emails with one connection. send_mass_mail() looks perfect but I can't figure out how I call this in combination with EmailMultiAlternatives.

This is my code that sends only one email with one connection:

html_content = render_to_string('newsletter.html', {'newsletter': n,})                text_content = "..."                       msg = EmailMultiAlternatives("subject", text_content, "from@bla", ["to@bla"])                                       msg.attach_alternative(html_content, "text/html")                                                                                                                                                                                msg.send()   

a working example with the code above and send_mass_mail would be great, thanks!

Answer 1

That is send_mass_mail() rewritten to use EmailMultiAlternatives:

from django.core.mail import get_connection, EmailMultiAlternatives  def send_mass_html_mail(datatuple, fail_silently=False, user=None, password=None,                          connection=None):     """     Given a datatuple of (subject, text_content, html_content, from_email,     recipient_list), sends each message to each recipient list. Returns the     number of emails sent.      If from_email is None, the DEFAULT_FROM_EMAIL setting is used.     If auth_user and auth_password are set, they're used to log in.     If auth_user is None, the EMAIL_HOST_USER setting is used.     If auth_password is None, the EMAIL_HOST_PASSWORD setting is used.      """     connection = connection or get_connection(         username=user, password=password, fail_silently=fail_silently)     messages = []     for subject, text, html, from_email, recipient in datatuple:         message = EmailMultiAlternatives(subject, text, from_email, recipient)         message.attach_alternative(html, 'text/html')         messages.append(message)     return connection.send_messages(messages)
