How to Send Emails Using SendGrid API and Python

Install Required Libraries

• To send emails using the SendGrid API with Python, first ensure you have the required libraries. Install them using pip:

pip install sendgrid

Set Up Your API Key

• After installing the library, you need to securely store your SendGrid API key. Set it as an environment variable:

import os
os.environ['SENDGRID_API_KEY'] = 'YOUR_SENDGRID_API_KEY'

Import Required Modules

• In your Python script, import the necessary modules to begin working with the SendGrid API:

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

Create the Email Content

• Now, define the content of your email. Create a `Mail` object that includes sender, recipient, subject, and body of the email:

def create_email(sender, recipient, subject, content):
    message = Mail(
        from_email=sender,
        to_emails=recipient,
        subject=subject,
        html_content=content
    )
    return message

Send the Email via SendGrid

• After creating the email content, use the SendGrid client to send the email:

def send_email(message):
    try:
        sg = SendGridAPIClient(os.environ.get('SENDGRID_API_KEY'))
        response = sg.send(message)
        print(f"Email sent! Status code: {response.status_code}")
    except Exception as e:
        print(f"Error: {e}")

Utilize the Functions

• With the helper functions defined, you can now create and send an email:

if __name__ == "__main__":
    sender = 'your-email@example.com'
    recipient = 'recipient-email@example.com'
    subject = 'Hello from SendGrid'
    content = '<strong>This is a test email using SendGrid and Python!</strong>'
    
    message = create_email(sender, recipient, subject, content)
    send_email(message)
