Python Django send_mail newlines?

Try sending your email as HTML instead of plain text. Use EmailMessage().

from django.core.mail import EmailMessage

msg = EmailMessage(
    'Test',
    'asdfasdfasdf<br>asdfasfasdfasdf<br>asdfasdfasdf',
    '[email protected]',
    ['[email protected]', ]
)
msg.content_subtype = "html"
msg.send()
