How To Send Bulk Email Using Sendgrid

by

Bulk email sending becomes vital for marketing, user engagement, and other projects that involve mass communication. To accomplish this task, a valuable tool is SendGrid. This article will walk you through the steps of utilizing SendGrid for sending bulk emails.

Setting Up SendGrid

To get started, you’ll first need to create an account on SendGrid’s website. Once you have an account, navigate to the ‘Setup Guide’ under the ‘Settings’ tab on SendGrid’s dashboard. There, you can create a unique API key for your application to use when making requests to SendGrid’s servers.

Remember to save your API key, as you’ll need it to authenticate your application later on.

Preparing the Email List

Before you start sending emails, you need to prepare your email list. Your email list should be in CSV format, with each line representing a unique recipient, and each recipient’s email address is on its own line. For example:

email@example.com
anotheremail@example.com

Sending Bulk Emails with SendGrid

Once you’ve prepared your email list, you can start sending emails. Here’s a simple example of how you could do this in Python, using SendGrid’s Python library:

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

def send_bulk_email(sendgrid_api_key, email_list_csv_file):
    # Create a new SendGrid client.
    sg = SendGridAPIClient(sendgrid_api_key)
    
    # Load the email list from the CSV file.
    with open(email_list_csv_file, 'r') as f:
        email_list = list(csv.reader(f))
    
    # Create a new email.
    email = Mail(
        from_email='from_email@example.com',
        subject='Your Email Subject',
        html_content='<strong>Your Email Body</strong>'
    )
    
    # Add each recipient to the email.
    for recipient in email_list:
        email.add_to(recipient[0])
    
    # Send the email.
    response = sg.send(email)
    print('Response:', response.status_code)

In the above code, replace ‘from_email@example.com’ with your SendGrid authenticated sender email, ‘Your Email Subject’ with your email subject, and ‘Your Email Body’ with your email body.

By running this script and passing your SendGrid API key and the path to your email list CSV file to the send_bulk_email function, you can send your email to all recipients in the list.
