Setting Up a SendGrid Account and Generating API Key

To get started with sending emails in Python using SendGrid API, you first need an account. Go to SendGrid’s website and create a free account.

Once logged in, we need to create API key for sending email from python script. Navigate to API keys under setting or you can use Setting > API keys link.

Generate new API key for your project. It will ask to enter name for project and permissions for key. Once key is created, save it somewhere safe. In further example we will use this key.

Install Required Package and Configuration

To send emails in Python using the SendGrid API, install the official Python package using pip. Open your terminal and enter below command to install sendgrid package for python :

pip install sendgrid

You will also need to set your SendGrid API key as an environment variable:

export SENDGRID_API_KEY='your_api_key_here'

Send Email in Python Using SendGrid API

Our setup is complete. Now, we can move forward with practical example like sending welcome email to user.

import os
from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import Mail

message = Mail(
    from_email='your_email@codewolfy.com',
    to_emails='newuser@codewolfy.com',
    subject='Welcome to Codewolfy',
    html_content='<strong>Thank you for registering with us!</strong>'
)

sg = SendGridAPIClient(os.environ.get('SENDGRID_API_KEY'))
response = sg.send(message)
print(response.status_code)

As you can see in this example, we are importing SendGrid and os library and creating mail instance with mail configuration like sender’s email, receiver’s email, subject, and content. At last, we are sending mail and printing response code for confirmation.
