Django: How to send HTML emails with embedded images

Question

How can I send HTML emails with embedded images? How the HTML should link to the images? The images should be added as MultiPart email attach?

Any example is very appreciated.

Answer 1

I achieved what op is asking for using django's mailing system. Upsides it that it'll use django settings for mailing (including a different subsystem for testing, etc. I also use mailhogs during development). It's also quite a bit higher level:

from django.conf import settings from django.core.mail import EmailMultiAlternatives   message = EmailMultiAlternatives(     subject=subject,     body=body_text,     from_email=settings.DEFAULT_FROM_EMAIL,     to=recipients,     **kwargs ) message.mixed_subtype = 'related' message.attach_alternative(body_html, "text/html") message.attach(logo_data())  message.send(fail_silently=False) 

logo_data is a helper function that attaches the logo (the image I wanted to attach in this case):

from email.mime.image import MIMEImage  from django.contrib.staticfiles import finders   @lru_cache() def logo_data():     with open(finders.find('emails/logo.png'), 'rb') as f:         logo_data = f.read()     logo = MIMEImage(logo_data)     logo.add_header('Content-ID', '<logo>')     return logo

You have to use MultiPart and cid:. It is almost always a bad idea to send html mails with images. It gives spam points to your mail and smtp server ...
