title: djagno send html email with static file attachment such as css and js and images
body: <p>I'm setting up a website for my self that send email with attachment.
  I used this link <a href="https://stackoverflow.com/questions/3005080/how-to-send-html-email-with-django-with-dynamic-content-in-it">How to send html email with django with dynamic content in it?</a>  but when I send email according to this link, static files like my images and my css and js files didn't send with my email.</p>
  
  <p>here my code :</p>
  
  <pre><code>subject, from_email, to = "WebSite Newsletter Subscribe", settings.EMAIL_HOST_USER, [instance.email]
          html_content = render_to_string('newsletter/Email.html')
          text_content = strip_tags(html_content)
          msg = EmailMultiAlternatives(subject, text_content, from_email, [to])
          msg.attach_alternative(html_content, "text/html")
          msg.send()`
  </code></pre>
  
  <p>but in this code email send with bare html and not css and js doesn't include and my images doesn't attached too.
