How To Send Multiple Emails Using Sendgrid

SendGrid is a cloud-based SMTP service that enables you to send emails without the need for managing email servers. In this tutorial, we will demonstrate how to send multiple emails using SendGrid.


  • Python installed on your system.
  • A SendGrid account and API key.

Steps to Send Multiple Emails

Here is a step by step guide on how to send multiple emails using SendGrid’s v3 API:

Step 1: Install SendGrid Library

Start by installing the SendGrid library in your python environment using pip:

    pip install sendgrid

Step 2: Import SendGrid

Import the SendGrid library in your python script and initialize it using your API Key:

    import sendgrid
    from sendgrid.helpers.mail import *
    sg = sendgrid.SendGridAPIClient(api_key='your_sendgrid_api_key')

Step 3: Create Email Function

Create a function to handle the email details. For example:

    def send_email(to_email, from_email, subject, content):
        message = Mail(
        response = sg.send(message)
        return response.status_code

Step 4: Call the Function Multiple Times

You can now call this function as many times as you need to send multiple emails. For example:

    send_email('[email protected]', '[email protected]', 'Test Subject 1', 'Test Content 1')
    send_email('[email protected]', '[email protected]', 'Test Subject 2', 'Test Content 2')

And there you have it! By following these steps, you can easily send multiple emails with SendGrid. Remember to always keep your API keys secure and do not expose them in your scripts.


SendGrid is a powerful tool for sending emails, and with just a few lines of code, you can easily send multiple emails. Whether you’re sending out a batch of welcome emails to new users, or running a large-scale email marketing campaign, SendGrid has you covered.
