A Django app that allows you to log email activities and send mail asynchronously.
Django Post Office is a simple app that allows you to log email activities and asynchronously send emails in django. Supports HTML email.
post_office is implemented as a Django EmailBackend so you don’t need to change any of your code to start sending email asynchronously.
Install via pypi:
pip install django-post_office
Add post_office to your INSTALLED_APPS in django’s settings.py:
INSTALLED_APPS = ( # other apps "post_office", )
python manage.py syncdb
Set post_office.EmailBackend as your EMAIL_BACKEND in django’s settings.py:
EMAIL_BACKEND = 'post_office.EmailBackend'
If you use post_office’s EmailBackend, it will automatically queue emails sent using django’s send_mail in the database.
To actually send them out, run python manage.py send_queued_mail. You can schedule this to run regularly via cron:
* * * * * (/usr/bin/python manage.py send_queued_mail >> send_mail.log 2>&1)
By default, post_office uses django’s SMTP EmailBackend. If you want to use a different backend, you can do so by changing POST_OFFICE_BACKEND.
For example if you want to use django-ses:
POST_OFFICE_BACKEND = 'django_ses.SESBackend'
You can view also queued emails along with their statuses if you have django’s admin interface enabled:
INSTALLED_APPS = ( # ... 'django.contrib.admin', # ... )
- send_queued_mail - send queued emails, those that aren’t successfully sent they will be marked as failed.
- cleanup_mail - delete all emails created before an X number of days (defaults to 90).
You may want to set these up via cron to run regularly:
* * * * * (cd $PROJECT; python manage.py send_queued_mail >> $PROJECT/cron_mail.log 2>&1) 0 1 * * * (cd $PROJECT; python manage.py cleanup_mail --days=30 >> $PROJECT/cron_mail_cleanup.log 2>&1)
Lower Level Usage
post_office also comes with a send_mail command similar to django’s. It accepts two extra arguments, html_message and priority (high, medium, low or now).
Here’s how to use it:
from post_office import send_mail, PRIORITY send_mail('subject', 'plaintext message', 'firstname.lastname@example.org', ['email@example.com'], '<p>HTML message</p>', priority=PRIORITY.medium)
post_office is also task queue friendly. Passing now as priority into send_mail will deliver the email right away, regardless of how many emails you have in your queue:
from post_office import send_mail, PRIORITY send_mail('subject', 'plaintext message', 'firstname.lastname@example.org', ['email@example.com'], '<p>HTML message</p>', priority=PRIORITY.now)
This is useful if you already use something like django-rq to send emails asynchronously and only need to store email activities and logs.
