SparkPost Python API client

Build Status Documentation Status Coverage Status

The official Python package for using the SparkPost API.



Install from PyPI using pip:

$ pip install sparkpost

Python 2.7 or later is required.

Get a key

Go to API & SMTP in the SparkPost app and create an API key. We recommend using the SPARKPOST_API_KEY environment variable:

from sparkpost import SparkPost
sp = SparkPost() # uses environment variable

Alternatively, you can pass the API key to the SparkPost class:

from sparkpost import SparkPost
sp = SparkPost('YOUR API KEY')

For SparkPost EU and Enterprise accounts, pass in a second parameter to set the API host.

from sparkpost import SparkPost
sp = SparkPost('YOUR API KEY', '')

Send a message

Here at SparkPost, our messages are known as transmissions. Let’s use the underlying transmissions API to send a friendly test message:

from sparkpost import SparkPost

sp = SparkPost()

response = sp.transmissions.send(
    html='<p>Hello world</p>',
    subject='Hello from python-sparkpost'

# outputs {u'total_accepted_recipients': 1, u'id': u'47960765679942446', u'total_rejected_recipients': 0}

Django Integration

The SparkPost python library comes with an email backend for Django. Put the following configuration in file.

EMAIL_BACKEND = 'sparkpost.django.email_backend.SparkPostEmailBackend'

Replace API_KEY with an actual API key that you’ve generated in Get a Key section. Check out the full documentation on the Django email backend.

If you are using an EU account, set SPARKPOST_BASE_URI to The default value is

Using with Google Cloud

There are a few simple modifications necessary to enable the use of the underlying requests library that python-sparkpost uses. First, add the requests and requests-toolbelt to your project’s requirements.txt:


Then create or update your file to include the following:

import requests
import requests_toolbelt.adapters.appengine


Then deploy your app and you should be able to send using python-sparkpost on Google Cloud.


  1. Check for open issues or open a fresh issue to start a discussion around a feature idea or a bug.

  2. Fork the repository on GitHub and make your changes in a branch on your fork

  3. Write a test which shows that the bug was fixed or that the feature works as expected.

  4. Send a pull request. Make sure to add yourself to AUTHORS.
