How to send html email with django with dynamic content in it?
PythonDjangoPython Problem Overview
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.
Solution 2 - Python
Example:
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>

Solution 4 - Python
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.

Try this::::

# views.py
from django.http import HttpResponse
from django.template import Context
from django.template.loader import render_to_string, get_template
from django.core.mail import EmailMessage
def email_one(request):
subject = "I am a text email"
to = ['[email protected]']
from_email = '[email protected]'
ctx = {
'user': 'buddy',
'purchase': 'Books'
}
message = render_to_string('main/email/email.txt', ctx)
EmailMessage(subject, message, to=to, from_email=from_email).send()
return HttpResponse('email_one')
def email_two(request):
subject = "I am an HTML email"
to = ['[email protected]']
from_email = '[email protected]'
ctx = {
'user': 'buddy',
'purchase': 'Books'
}
message = get_template('main/email/email.html').render(Context(ctx))
msg = EmailMessage(subject, message, to=to, from_email=from_email)
msg.content_subtype = 'html'
msg.send()
return HttpResponse('email_two')

If you want dynamic email templates for your mail then save the email content in your database tables. This is what i saved as HTML code in database =
<p>Hello.. {{ first_name }} {{ last_name }}. <br> This is an <strong>important</strong> {{ message }}
<br> <b> By Admin.</b>
<p style='color:red'> Good Day </p>
In your views:
from django.core.mail import EmailMultiAlternatives
from django.template.loader import get_template
def dynamic_email(request):
application_obj = AppDetails.objects.get(id=1)
subject = 'First Interview Call'
email = request.user.email
to_email = application_obj.email
message = application_obj.message
text_content = 'This is an important message.'
d = {'first_name': application_obj.first_name,'message':message}
htmly = FirstInterviewCall.objects.get(id=1).html_content #this is what i have saved previously in database which i have to send as Email template as mentioned above HTML code
open("partner/templates/first_interview.html", "w").close() # this is the path of my file partner is the app, Here i am clearing the file content. If file not found it will create one on given path.
text_file = open("partner/templates/first_interview.html", "w") # opening my file
text_file.write(htmly) #putting HTML content in file which i saved in DB
text_file.close() #file close
htmly = get_template('first_interview.html')
html_content = htmly.render(d)
msg = EmailMultiAlternatives(subject, text_content, email, [to_email])
msg.attach_alternative(html_content, "text/html")
msg.send()
This will send the dynamic HTML template what you have save in Db.
