Getting Started with Django Email
Setting Up Django for Email
To begin sending emails in Django, you need to configure your project settings. Open your
settings.py file and locate the email configuration section. Here’s an example of how it should look:
# settings.py EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'your-smtp-server.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True EMAIL_HOST_USER = 'firstname.lastname@example.org' EMAIL_HOST_PASSWORD = 'your-email-password'
Make sure to replace the placeholders with your SMTP server details and email credentials.
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.', 'email@example.com', ['firstname.lastname@example.org'], 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.
Advanced Django Email Techniques
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 = 'email@example.com' recipient_list = ['firstname.lastname@example.org'] 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()
