Menu
Can anyone please help me sending html email with dynamic contents. One way is to copy the entire html code into a variable and populate the dynamic code within it in Django views, but that does not seem to be a good idea, as its a very large html file.
I would appreciate any suggestions.
Thanks.

Django includes the django.core.mail.send_mail method these days (2018), no need to use EmailMultiAlternatives class directly. Do this instead:
from django.core import mail
from django.template.loader import render_to_string
from django.utils.html import strip_tags
subject = 'Subject'
html_message = render_to_string('mail_template.html', {'context': 'values'})
plain_message = strip_tags(html_message)
from_email = 'From <[email protected]>'
to = '[email protected]'
mail.send_mail(subject, plain_message, from_email, [to], html_message=html_message)
This will send an email which is visible in both html-capable browsers and will show plain text in crippled email viewers.

from django.core.mail import EmailMultiAlternatives
from django.template.loader import render_to_string
from django.utils.html import strip_tags
subject, from_email, to = 'Subject', '[email protected]', '[email protected]'
html_content = render_to_string('mail_template.html', {'varname':'value'}) # render with dynamic value
text_content = strip_tags(html_content) # Strip the html tag. So people can see the pure text at least.
# create the email, and attach the HTML version as well.
msg = EmailMultiAlternatives(subject, text_content, from_email, [to])
msg.attach_alternative(html_content, "text/html")
msg.send()
For anyone looking at this in 2020 and using django v3.x (I don't know when this was introduced so it might work for earlier versions.
Note: I only wanted to include an html version without a plain text version. My django view:
from django.template.loader import render_to_string
from django.core.mail import EmailMessage
# import html message.html file
html_template = 'path/to/message.html'
html_message = render_to_string(html_template, { 'context': context, })
message = EmailMessage(subject, html_message, from_email, [to_email])
message.content_subtype = 'html' # this is required because there is no plain text email message
message.send()
My html file (message.html) looked like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Order received</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
</head>
<body style="margin: 0; padding: 0;">
<table align="center" border="0" cellpadding="0" cellspacing="0" width="320" style="border: none; border-collapse: collapse; font-family: Arial, sans-serif; font-size: 14px; line-height: 1.5;">
...
content
...
</table>
</body>
</html>

This should do what you want:
from django.core.mail import EmailMessage
from django.template import Context
from django.template.loader import get_template
template = get_template('myapp/email.html')
context = Context({'user': user, 'other_info': info})
content = template.render(context)
if not user.email:
raise BadHeaderError('No email address given for {0}'.format(user))
msg = EmailMessage(subject, content, from, to=[user.email,])
msg.send()
See the django mail docs for more.
