How to send asynchronous email using django

To send asynchronous email using Django, you can use Django's built-in support for sending email messages asynchronously. This can be achieved by using Django's django.core.mail module along with Django's @async support. Here are the steps to send asynchronous emails in Django:

  1. Configure Email Settings:

    First, make sure you have configured your email settings in your Django project's settings file (settings.py). You typically specify settings like the SMTP server, port, authentication credentials, etc. Here's an example:

    # settings.py EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'your-smtp-server.com' EMAIL_PORT = 587 # The port for your SMTP server EMAIL_USE_TLS = True EMAIL_HOST_USER = 'your-email@example.com' EMAIL_HOST_PASSWORD = 'your-email-password'

  2. Import Necessary Modules:

    Import the necessary modules in your Django views or tasks where you want to send asynchronous emails.

    from django.core import mail from django.core.mail import send_mail from django.db import models from asgiref.sync import async_to_sync

  3. Send the Asynchronous Email:

    Use the @async_to_sync decorator to make the email-sending function asynchronous. Here's an example:

    from asgiref.sync import async_to_sync from django.core.mail import send_mail @async_to_sync def send_async_email(): send_mail( 'Subject', 'Message', 'from@example.com', ['to@example.com'], fail_silently=False, )

    You can call this send_async_email function to send the email asynchronously.

  4. Calling the Asynchronous Email Function:

    To send the email asynchronously, you need to call the asynchronous function within an asynchronous context. You can use asyncio for this purpose. Here's an example:

    import asyncio loop = asyncio.get_event_loop() loop.run_until_complete(send_async_email())

  5. Run an Asynchronous Server:

    To use Django's asynchronous email functionality, you must run your Django project with an asynchronous server like Daphne, Uvicorn, or ASGI-compatible servers. This is necessary because Django's asynchronous email handling relies on ASGI (Asynchronous Server Gateway Interface) capabilities.

    For example, you can use Uvicorn to run your Django project:

    uvicorn your_project_name.asgi:application

By following these steps, you can send emails asynchronously in a Django project. Sending emails asynchronously can help improve the performance of your application, especially when sending multiple emails or when email sending might take a while.
