How to use

All you have to do is use send_mail or EmailMessage just like the old time, you don't have to change your code.

Utilities

This package handle Blacklist for you by default, but sometimes, maybe you want to bypass the "blacklist check", you can use pass_blacklist to pass the "backlist check" like this.

from djcelery_ses.utils import pass_blacklist
from django.core.mail import EmailMessage

with pass_blacklist:
    msg = EmailMessage('title', 'body content', 'noreply@example.com', ['noreply@example.com'])
    msg.send()

or in some situations, you don't want the email to send through Celery queue, you can use no_delay, for example.

since version 0.9

from djcelery_ses.utils import no_delay
from django.core.mail import send_mail

with no_delay:
    send_mail('title', 'body content', 'noreply@example.com', ['noreply@example.com'])
