Question: Write a Python program to send bulk emails using Gmail.

				
					#Install required modules & libraries
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

Explanation:

To install library or module enter the following code in the terminal:

pip install smtplib email

  1. The smtplib is a Python module to connect with Gmail’s SMTP live server.
  2. The email module is a Python package to handle the emails.
  3. The MIMEMultipart is a library which adds additional features to email like: subject, body, attachment, etc.
  4. The MIMEText decides the email format: Plain or HTML (bold, italic, headings, etc.).
				
					# Gmail credentials
SENDER_EMAIL = "your_email@gmail.com"
SENDER_PASSWORD = "your_App_password"

# List of recipients
recipients = ["recipient1@example.com", "recipient2@example.com", "recipient3@example.com"]

# Email subject and body
subject = "Bulk Email Test"
body = "Hello,This is a test email sent using Python."

Steps to create App Password:

  1. Login to gmail account
  2. Go to Account manage option
  3. Go to under Security option
  4. Security > enable 2 step verification (mandatory)
  5. In search section, search App Password
  6. App Password >  enter the app name > get the App Password from Gmail.
				
					try:
     #Gmail SMTP Path and Port no.
    server = smtplib.SMTP("smtp.gmail.com", 587)
    server.starttls()  # Secure connection
    server.login(SENDER_EMAIL, SENDER_PASSWORD)

Explanation: The SMTP establishes the local host to the system to connect with Gmail’s server. The login method is used to log into the server with login details.

				
					for recipient in recipients:
        msg = MIMEMultipart()
        msg["From"] = SENDER_EMAIL
        msg["To"] = recipient
        msg["Subject"] = subject
        msg.attach(MIMEText(body, "plain"))

Explanation: The for loop is used to access each email address one by one. The attach method is used to attach all email features to the main email body.

				
					#Send email
        server.sendmail(SENDER_EMAIL, recipient, msg.as_string())
        print(f"Email sent to {recipient}")

Explanation: The sendmail method is used to start the whole process of sending the emails to the recipients.

				
					server.quit()
print("All emails sent successfully!")

Explanation: The quit() method is used to disconnect from the SMTP server after sending all emails successfully.

				
					except Exception as e:
    print(f"Error: {e}")

Explanation: The except clause is used to handle the error if found any error in the try clause. try clause let’s test the code for error while except clause raises an exception and handles the error.

Complete Code:

				
					import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

# Gmail credentials
SENDER_EMAIL = "your_email@gmail.com"
SENDER_PASSWORD = "your_password_or_app_password"

# List of recipients
recipients = ["recipient1@example.com", "recipient2@example.com", "recipient3@example.com"]

# Email subject and body
subject = "Bulk Email Test"
body = "Hello,This is a test email sent using Python."

# Setting up the SMTP server
try:
    server = smtplib.SMTP("smtp.gmail.com", 587)
    server.starttls()  # Secure connection
    server.login(SENDER_EMAIL, SENDER_PASSWORD)

    for recipient in recipients:
        msg = MIMEMultipart()
        msg["From"] = SENDER_EMAIL
        msg["To"] = recipient
        msg["Subject"] = subject
        msg.attach(MIMEText(body, "plain"))

        # Send email
        server.sendmail(SENDER_EMAIL, recipient, msg.as_string())
        print(f"Email sent to {recipient}")

    server.quit()
    print("All emails sent successfully!")

except Exception as e:
    print(f"Error: {e}")
