An implementation of Django's EmailBackend compatible with sendgrid-python v5+

Project description

django-sendgrid-v5

Latest Release

This package implements an email backend for Django that relies on sendgrid's REST API for message delivery.

It is under active development, and pull requests are more than welcome!

To use the backend, simply install the package (using pip), set the EMAIL_BACKEND setting in Django, and add a SENDGRID_API_KEY key (set to the appropriate value) to your Django settings.

How to Install

  1. pip install django-sendgrid-v5
  2. In your project's settings.py script:
    1. Set EMAIL_BACKEND = "sendgrid_backend.SendgridBackend"
    2. Set the SENDGRID_API_KEY in settings.py to your api key that was provided to you by sendgrid. SENDGRID_API_KEY = os.environ["SENDGRID_API_KEY"]

Other settings

  1. To toggle sandbox mode (when django is running in DEBUG mode), set SENDGRID_SANDBOX_MODE_IN_DEBUG = True/False.
    1. To err on the side of caution, this defaults to True, so emails sent in DEBUG mode will not be delivered, unless this setting is explicitly set to False.
  2. SENDGRID_ECHO_TO_STDOUT will echo to stdout or any other file-like object that is passed to the backend via the stream kwarg.
  3. SENDGRID_TRACK_EMAIL_OPENS - defaults to true and tracks email open events via the Sendgrid service. These events are logged in the Statistics UI, Email Activity interface, and are reported by the Event Webhook.
  4. SENDGRID_TRACK_CLICKS_HTML - defaults to true and, if enabled in your Sendgrid account, will tracks click events on links found in the HTML message sent.
  5. SENDGRID_TRACK_CLICKS_PLAIN - defaults to true and, if enabled in your Sendgrid account, will tracks click events on links found in the plain text message sent.

Usage

Simple

from django.core.mail import send_mail

send_mail(
    'Subject here',
    'Here is the message.',
    'from@example.com',
    ['to@example.com'],
    fail_silently=False,
)

Dynamic Template with JSON Data

First, create a dynamic template and copy the ID.

from django.core.mail import EmailMessage

msg = EmailMessage(
  from_email='to@example.com',
  to=['to@example.com'],
)
msg.template_id = "your-dynamic-template-id"
msg.dynamic_template_data = {
  "title": foo
}
msg.send(fail_silently=False)

The kitchen sink EmailMessage (all of the supported sendgrid-specific properties)

from django.core.mail import EmailMessage

msg = EmailMessage(
  from_email='to@example.com',
  to=['to@example.com'],
  cc=['cc@example.com'],
  bcc=['bcc@example.com'],
)

# Personalization custom args
# https://sendgrid.com/docs/for-developers/sending-email/personalizations/
msg.custom_args = {'arg1': 'value1', 'arg2': 'value2'}

# Reply to email address (sendgrid only supports 1 reply-to email address)
msg.reply_to = 'reply-to@example.com'

# Send at (accepts an integer per the sendgrid docs)
# https://docs.sendgrid.com/for-developers/sending-email/scheduling-parameters#send-at
msg.send_at = 1600188812

# Transactional templates
# https://sendgrid.com/docs/ui/sending-email/how-to-send-an-email-with-dynamic-transactional-templates/
msg.template_id = "your-dynamic-template-id"
msg.dynamic_template_data = {  # Sendgrid v6+ only
  "title": foo
}
msg.substitutions = {
  "title": bar
}

# Unsubscribe groups
# https://sendgrid.com/docs/ui/sending-email/unsubscribe-groups/
msg.asm = {'group_id': 123, 'groups_to_display': ['group1', 'group2']}

# Categories
# https://sendgrid.com/docs/glossary/categories/
msg.categories = ['category1', 'category2']

# IP Pools
# https://sendgrid.com/docs/ui/account-and-settings/ip-pools/
msg.ip_pool_name = 'my-ip-pool'


msg.send(fail_silently=False)

FAQ

How to change a Sender's Name ?

from_email="John Smith <john.smith@example.org>" You can just include the name in the from_email field of the EmailMessage class

msg = EmailMessage(
  from_email='Sender Name <from@example.com>',
  to=['to@example.com'],
)

How to make mails to multiple users private (hide all the email addresses to which the mail is sent) to each person (personalization) ?

Setting the make_private attribute to True will help us achieve it

msg = EmailMessage(
  from_email='Sender Name <from@example.com>',
  to=['to@example.com','abc@example.com','xyz@example.com'],
)
msg.make_private = True
