docs: send_templated_mail() is a wrapper around Django's e-mail routines that
      allows us to easily send multipart (text/plain & text/html) e-mails using
      templates that are stored in the database. This lets the admin provide
      both a text and a HTML template for each message.
  
      template_name is the slug of the template to use for this message (see
          models.EmailTemplate)
  
      context is a dictionary to be used when rendering the template
  
      recipients can be either a string, eg 'a@b.com', or a list of strings.
  
      sender should contain a string, eg 'My Site <me@z.com>'. If you leave it
          blank, it'll use settings.DEFAULT_FROM_EMAIL as a fallback.
  
      bcc is an optional list of addresses that will receive this message as a
          blind carbon copy.
  
      fail_silently is passed to Django's mail routine. Set to 'True' to ignore
          any errors at send time.
  
      files can be a list of file paths to be attached, or it can be left blank.
          eg ('/tmp/file1.txt', '/tmp/image.png')
