How create email templates with Django

From the docs, to send HTML e-mail you want to use alternative content-types, like this:

from django.core.mail import EmailMultiAlternatives

subject, from_email, to = 'hello', 'from@example.com', 'to@example.com'
text_content = 'This is an important message.'
html_content = '<p>This is an <strong>important</strong> message.</p>'
msg = EmailMultiAlternatives(subject, text_content, from_email, [to])
msg.attach_alternative(html_content, "text/html")
msg.send()

Or You can then send an e-mail using both those templates by making use of get_template, like this:

from django.core.mail import EmailMultiAlternatives
from django.template.loader import get_template
from django.template import Context

plaintext = get_template('email.txt')
html_template     = get_template('email.html')

d = Context({ 'username': username })

subject, from_email, to = 'hello', 'from@example.com', 'to@example.com'
text_content = plaintext.render(d)
html_content = html_template.render(d)
msg = EmailMultiAlternatives(subject, text_content, from_email, [to])
msg.attach_alternative(html_content, "text/html")
msg.send()

Or Since Django’s 1.7 in send_email method the html_message parameter was added

from django.core.mail import send_mail
from django.template.loader import render_to_string


msg_plain = render_to_string('templates/email.txt', {'some_params': some_params})
msg_html = render_to_string('templates/email.html', {'some_params': some_params})

send_mail(
    'email title',
    msg_plain,
    'some@sender.com',
    ['some@receiver.com'],
    html_message=msg_html,
)
