Getting Started with Django Email

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'your-smtp-server.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = 'your-email@example.com'
EMAIL_HOST_PASSWORD = 'your-email-password'

Sending a Simple Email

Sending a basic email in Django is straightforward. Use the following code snippet to send a simple email:

from django.core.mail import send_mail

send_mail(
    'Subject here',
    'Here is the message.',
    'from@example.com',
    ['to@example.com'],
    fail_silently=False,
)

This function allows you to specify the subject, message, sender’s email, recipient(s), and whether to fail silently if there’s an error.

Sending HTML Emails

Django allows you to send HTML-formatted emails, perfect for newsletters and rich content. Create an HTML template, and use the EmailMultiAlternatives class to send it:

from django.core.mail import EmailMultiAlternatives

subject = 'Subject here'
message = 'Here is the message.'
from_email = 'from@example.com'
recipient_list = ['to@example.com']

html_message = '<p>This is an HTML message!</p>'

msg = EmailMultiAlternatives(subject, message, from_email, recipient_list)
msg.attach_alternative(html_message, "text/html")
msg.send()

Attaching Files to Emails

from django.core.mail import EmailMessage

email = EmailMessage(
    'Subject here',
    'Here is the message.',
    'from@example.com',
    ['to@example.com'],
)
email.attach_file('path/to/attachment.pdf')
email.send()
