Welcome to our comprehensive guide on Django email sending! If you’re struggling to set up email notifications in your Django project, you’re in the right place. In this article, we’ll take you by the hand and walk you through the process of sending emails in Django, covering everything from the basics to advanced techniques.
Why Send Emails in Django?
Emails are an essential part of any web application. They provide a way to communicate with users, notify them of important events, and even help with password recovery. In Django, sending emails is a breeze, and we’ll show you how to do it like a pro.
The Benefits of Django Email Sending
- Improved user engagement: Keep your users informed and engaged with personalized email notifications.
- Enhanced security: Use email verification to ensure users have a valid email address.
- Automated workflows: Send automated emails to trigger specific actions or notifications.
- Better customer support: Respond to user inquiries and provide timely support via email.
Setting Up Email in Django
Configuring Email Settings
In your `settings.py` file, you’ll need to add the following configurations:
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = 'your_email_address'
EMAIL_HOST_PASSWORD = 'your_email_password'
Replace `your_email_address` and `your_email_password` with your actual email credentials.
Sending a Simple Email
Now that we have our email settings configured, let’s send a simple email using Django’s built-in `send_email` function.
The `send_email` Function
The `send_email` function takes four arguments:
- `subject`: The subject of the email.
- `message`: The body of the email.
- `from_email`: The sender’s email address.
- `recipient_list`: A list of recipient email addresses.
from django.core.mail import send_email
subject = 'Hello from Django!'
message = 'This is a test email sent from Django.'
from_email = 'your_email_address'
recipient_list = ['recipient_email_address']
send_email(subject, message, from_email, recipient_list)
Replace `your_email_address` with your actual email address and `recipient_email_address` with the recipient’s email address.
Using Email Templates
While the `send_email` function is useful for sending simple emails, it’s not ideal for sending complex emails with HTML content or attachments. That’s where email templates come in.
Creating an Email Template
Create a new file in your `templates` directory, e.g., `email_template.html`:
<html>
<head></head>
<body>
<p>Hello, {{ name }}!</p>
<p>This is a test email sent from Django.</p>
</body>
</html>
This template uses Django’s template language to inject variables into the email content.
Sending an Email with a Template
To send an email using the template, we’ll use the `EmailMessage` class:
from django.core.mail import EmailMessage
from django.template.loader import render_to_string
subject = 'Hello from Django!'
template_name = 'email_template.html'
context = {'name': 'John Doe'}
from_email = 'your_email_address'
recipient_list = ['recipient_email_address']
email = EmailMessage(
subject,
render_to_string(template_name, context),
from_email,
recipient_list
)
email.send()
This code renders the email template with the provided context and sends the email using the `EmailMessage` class.
Sending Emails with Attachments
Sending emails with attachments is a breeze in Django. We’ll use the `EmailMessage` class again, but this time, we’ll add an attachment.
Sending an Email with an Attachment
from django.core.mail import EmailMessage
subject = 'Hello from Django!'
message = 'This is a test email sent from Django.'
from_email = 'your_email_address'
recipient_list = ['recipient_email_address']
attachment = 'path/to/attachment.pdf'
email = EmailMessage(
subject,
message,
from_email,
recipient_list
)
email.attach_file(attachment)
email.send()
This code sends an email with a PDF attachment.
Advanced Email Sending Techniques
Now that we’ve covered the basics, let’s explore some advanced email sending techniques in Django.
Using Celery for Asynchronous Email Sending
Celery is a distributed task queue that allows you to run tasks asynchronously in the background. We can use Celery to send emails in the background, improving performance and responsiveness.
from celery import shared_task
from django.core.mail import send_email
@shared_task
def send_email_task(subject, message, from_email, recipient_list):
send_email(subject, message, from_email, recipient_list)
This code defines a Celery task that sends an email using the `send_email` function.
Using Email Services like SendGrid or Mailgun
While Django’s built-in email sending capabilities are sufficient for small-scale applications, they might not be suitable for large-scale applications. That’s where email services like SendGrid or Mailgun come in.
These services provide APIs for sending emails, offering features like email tracking, analytics, and deliverability optimization.
import requests
subject = 'Hello from Django!'
message = 'This is a test email sent from Django.'
from_email = 'your_email_address'
recipient_list = ['recipient_email_address']
api_key = 'your_sendgrid_api_key'
url = 'https://api.sendgrid.com/v3/mail/send'
auth = ('api_key', '')
data = {
'personalizations': [{
'to': recipient_list,
'subject': subject
}],
'from': {'email': from_email},
'content': [{'type': 'text/plain', 'value': message}]
}
response = requests.post(url, auth=auth, json=data)
This code sends an email using SendGrid’s API.
Conclusion
And that’s it! You now have a comprehensive understanding of Django email sending, from setting up email configurations to sending emails with attachments and using advanced techniques like Celery and email services.
Remember to optimize your email sending process for performance and deliverability, and don’t hesitate to explore more advanced features and techniques to take your email sending to the next level.

Happy emailing with Django!
Here are 5 FAQs about Django Email Sending:
Frequently Asked Questions
Get answers to your burning questions about sending emails with Django!
Q1: How do I set up email sending in my Django project?
To set up email sending in your Django project, you need to configure the EMAIL_HOST, EMAIL_PORT, EMAIL_HOST_USER, and EMAIL_HOST_PASSWORD settings in your settings.py file. You can then use the send_mail function from django.core.mail to send emails.
Q2: Can I use a template to send HTML emails in Django?
Yes, you can use a template to send HTML emails in Django! You can create an HTML template using Django’s templating language and then use the render_to_string function to render the template with dynamic data. Then, pass the rendered HTML to the EmailMessage object to send the email.
Q3: How do I send attachments with emails in Django?
To send attachments with emails in Django, you can use the EmailMessage object’s attach method to attach files to the email. You can attach files from a file path or from a file-like object.
Q4: Can I use a celery task to send emails asynchronously in Django?
Yes, you can use a Celery task to send emails asynchronously in Django! This can be useful if you want to offload the task of sending emails to a separate worker process, freeing up your main application to handle other tasks. You can use Celery’s apply_async method to run the email sending task asynchronously.
Q5: How do I test email sending in Django?
To test email sending in Django, you can use the EmailMessage object’s send method and set the connection to a dummy backend, such as the locmem email backend. This will store the emails in memory instead of sending them to an actual SMTP server. You can then assert that the email was sent correctly in your tests.
