Compatibility

This library mailjet_rest officially supports the following Python versions:

• Python >=3.10,<3.14

It's tested up to 3.13 (including).

Requirements

Build backend dependencies

To build the mailjet_rest package from the sources you need setuptools (as a build backend), wheel, and setuptools-scm.

Runtime dependencies

At runtime the package requires only requests >=2.32.4.

Test dependencies

For running test you need pytest >=7.0.0 at least. Make sure to provide the environment variables from Authentication.

Installation

pip install

Use the below code to install the the wrapper:

pip install mailjet-rest

git clone & pip install locally

Use the below code to install the wrapper locally by cloning this repository:

git clone https://github.com/mailjet/mailjet-apiv3-python
cd mailjet-apiv3-python

pip install .

conda & make

Use the below code to install it locally by conda and make on Unix platforms:

make install

For development

Using conda

on Linux or macOS:

• A basic environment with a minimum number of dependencies:

make dev
conda activate mailjet

• A full dev environment:

make dev-full
conda activate mailjet-dev

Authentication

The Mailjet Email API uses your API and Secret keys for authentication. Grab and save your Mailjet API credentials.

export MJ_APIKEY_PUBLIC='your api key'
export MJ_APIKEY_PRIVATE='your api secret'

Initialize your Mailjet client:

# import the mailjet wrapper
from mailjet_rest import Client
import os

# Get your environment Mailjet keys
api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]

mailjet = Client(auth=(api_key, api_secret))

Make your first call

Here's an example on how to send an email:

from mailjet_rest import Client
import os

api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]
mailjet = Client(auth=(api_key, api_secret))
data = {
    "FromEmail": "$SENDER_EMAIL",
    "FromName": "$SENDER_NAME",
    "Subject": "Your email flight plan!",
    "Text-part": "Dear passenger, welcome to Mailjet! May the delivery force be with you!",
    "Html-part": '<h3>Dear passenger, welcome to <a href="https://www.mailjet.com/">Mailjet</a>!<br />May the delivery force be with you!',
    "Recipients": [{"Email": "$RECIPIENT_EMAIL"}],
}
result = mailjet.send.create(data=data)
print(result.status_code)
print(result.json())

Client / Call Configuration Specifics

API Versioning

The Mailjet API is spread among three distinct versions:

• v3 - The Email API
• v3.1 - Email Send API v3.1, which is the latest version of our Send API
• v4 - SMS API (not supported in Python)

Since most Email API endpoints are located under v3, it is set as the default one and does not need to be specified when making your request. For the others you need to specify the version using version. For example, if using Send API v3.1:

# import the mailjet wrapper
from mailjet_rest import Client
import os

# Get your environment Mailjet keys
api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]

mailjet = Client(auth=(api_key, api_secret), version="v3.1")

For additional information refer to our API Reference.

Base URL

The default base domain name for the Mailjet API is api.mailjet.com. You can modify this base URL by setting a value for api_url in your call:

mailjet = Client(auth=(api_key, api_secret), api_url="https://api.us.mailjet.com/")

If your account has been moved to Mailjet's US architecture, the URL value you need to set is https://api.us.mailjet.com.

URL path

According to python special characters limitations we can't use slashes / and dashes - which is acceptable for URL path building. Instead python client uses another way for path building. You should replace slashes / by underscore _ and dashes - by capitalizing next letter in path. For example, to reach statistics/link-click path you should call statistics_linkClick attribute of python client.

# GET `statistics/link-click`
mailjet = Client(auth=(api_key, api_secret))
filters = {"CampaignId": "xxxxxxx"}
result = mailjet.statistics_linkClick.get(filters=filters)
print(result.status_code)
print(result.json())

Request examples

Full list of supported endpoints

Important

This is a full list of supported endpoints this wrapper provides samples

POST request

Simple POST request

"""
Create a new contact:
"""

from mailjet_rest import Client
import os

api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]
mailjet = Client(auth=(api_key, api_secret))
data = {"Email": "Mister@mailjet.com"}
result = mailjet.contact.create(data=data)
print(result.status_code)
print(result.json())

Using actions

"""
Manage the subscription status of a contact to multiple lists:
"""

from mailjet_rest import Client
import os

api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]
mailjet = Client(auth=(api_key, api_secret))
id = "$ID"
data = {
    "ContactsLists": [
        {"ListID": "$ListID_1", "Action": "addnoforce"},
        {"ListID": "$ListID_2", "Action": "addforce"},
    ]
}
result = mailjet.contact_managecontactslists.create(id=id, data=data)
print(result.status_code)
print(result.json())

GET Request

Retrieve all objects

"""
Retrieve all contacts:
"""

from mailjet_rest import Client
import os

api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]
mailjet = Client(auth=(api_key, api_secret))
result = mailjet.contact.get()
print(result.status_code)
print(result.json())

Using filtering

"""
Retrieve all contacts that are not in the campaign exclusion list:
"""

from mailjet_rest import Client
import os

api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]
mailjet = Client(auth=(api_key, api_secret))
filters = {
    "IsExcludedFromCampaigns": "false",
}
result = mailjet.contact.get(filters=filters)
print(result.status_code)
print(result.json())

Using pagination

Some requests (for example GET /contact) has limit, offset and sort query string parameters. These parameters could be used for pagination. limit int Limit the response to a select number of returned objects. Default value: 10. Maximum value: 1000 offset int Retrieve a list of objects starting from a certain offset. Combine this query parameter with limit to retrieve a specific section of the list of objects. Default value: 0 sort str Sort the results by a property and select ascending (ASC) or descending (DESC) order. The default order is ascending. Keep in mind that this is not available for all properties. Default value: ID asc Next example returns 40 contacts starting from 51th record sorted by Email field descendally:

import os
from mailjet_rest import Client

api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]
mailjet = Client(auth=(api_key, api_secret))

filters = {
    "limit": 40,
    "offset": 50,
    "sort": "Email desc",
}
result = mailjet.contact.get(filters=filters)
print(result.status_code)
print(result.json())

Retrieve a single object

"""
Retrieve a specific contact ID:
"""

from mailjet_rest import Client
import os

api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]
mailjet = Client(auth=(api_key, api_secret))
id_ = "Contact_ID"
result = mailjet.contact.get(id=id_)
print(result.status_code)
print(result.json())

PUT request

A PUT request in the Mailjet API will work as a PATCH request - the update will affect only the specified properties. The other properties of an existing resource will neither be modified, nor deleted. It also means that all non-mandatory properties can be omitted from your payload.

Here's an example of a PUT request:

"""
Update the contact properties for a contact:
"""

from mailjet_rest import Client
import os

api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]
mailjet = Client(auth=(api_key, api_secret))
id_ = "$CONTACT_ID"
data = {
    "Data": [
        {"Name": "first_name", "value": "John"},
        {"Name": "last_name", "value": "Smith"},
    ]
}
result = mailjet.contactdata.update(id=id_, data=data)
print(result.status_code)
print(result.json())

DELETE request

Upon a successful DELETE request the response will not include a response body, but only a 204 No Content response code.

Here's an example of a DELETE request:

"""
Delete an email template:
"""

from mailjet_rest import Client
import os

api_key = os.environ["MJ_APIKEY_PUBLIC"]
api_secret = os.environ["MJ_APIKEY_PRIVATE"]
mailjet = Client(auth=(api_key, api_secret))
id_ = "Template_ID"
result = mailjet.template.delete(id=id_)
print(result.status_code)
print(result.json())
