Open Source Helpers

This library allows you to quickly and easily use the SendGrid Web API v3 via Python.

Version 3.X.X+ of this library provides full support for all SendGrid Web API v3 endpoints, including the new v3 /mail/send.

This library represents the beginning of a new path for SendGrid. We want this library to be community driven and SendGrid led. We need your help to realize this goal. To help make sure we are building the right things in the right order, we ask that you create issues and pull requests or simply upvote or comment on existing issues or pull requests.

If you need help using SendGrid, please check the Twilio SendGrid Support Help Center.

Please browse the rest of this README for further detail.

Installation

Prerequisites

• Python version 2.7+
• The SendGrid service, starting at the free level

Setup Environment Variables

Mac

Update the development environment with your SENDGRID_API_KEY (more info here), for example:

echo "export SENDGRID_API_KEY='YOUR_API_KEY'" > sendgrid.env
echo "sendgrid.env" >> .gitignore
source ./sendgrid.env

SendGrid also supports local environment file .env. Copy or rename .env_sample into .env and update SENDGRID_API_KEY with your key.

Windows

Temporarily set the environment variable(accessible only during the current cli session):

set SENDGRID_API_KEY=YOUR_API_KEY

Permanently set the environment variable(accessible in all subsequent cli sessions):

setx SENDGRID_API_KEY "YOUR_API_KEY"

Install Package

pip install sendgrid

Dependencies

• Python-HTTP-Client
• Cryptography

Quick Start

Hello Email

The following is the minimum needed code to send an email with the /mail/send Helper (here is a full example):

With Mail Helper Class

import sendgrid
import os
from sendgrid.helpers.mail import *

sg = sendgrid.SendGridAPIClient(api_key=os.environ.get('SENDGRID_API_KEY'))
from_email = Email("test@example.com")
to_email = To("test@example.com")
subject = "Sending with SendGrid is Fun"
content = Content("text/plain", "and easy to do anywhere, even with Python")
mail = Mail(from_email, to_email, subject, content)
response = sg.client.mail.send.post(request_body=mail.get())
print(response.status_code)
print(response.body)
print(response.headers)

The Mail constructor creates a personalization object for you. Here is an example of how to add it.

Without Mail Helper Class

The following is the minimum needed code to send an email without the /mail/send Helper (here is a full example):

import sendgrid
import os

sg = sendgrid.SendGridAPIClient(api_key=os.environ.get('SENDGRID_API_KEY'))
data = {
  "personalizations": [
    {
      "to": [
        {
          "email": "test@example.com"
        }
      ],
      "subject": "Sending with SendGrid is Fun"
    }
  ],
  "from": {
    "email": "test@example.com"
  },
  "content": [
    {
      "type": "text/plain",
      "value": "and easy to do anywhere, even with Python"
    }
  ]
}
response = sg.client.mail.send.post(request_body=data)
print(response.status_code)
print(response.body)
print(response.headers)

General v3 Web API Usage (With Fluent Interface)

import sendgrid
import os

sg = sendgrid.SendGridAPIClient(api_key=os.environ.get('SENDGRID_API_KEY'))
response = sg.client.suppression.bounces.get()
print(response.status_code)
print(response.body)
print(response.headers)

General v3 Web API Usage (Without Fluent Interface)

import sendgrid
import os

sg = sendgrid.SendGridAPIClient(api_key=os.environ.get('SENDGRID_API_KEY'))
response = sg.client._("suppression/bounces").get()
print(response.status_code)
print(response.body)
print(response.headers)
