This script automates sending personalized emails to multiple recipients using Python's built-in smtplib and csv modules. It reads recipient details from a CSV file and sends customized emails to each one.

No external libraries are required as the script uses built-in Python modules:

import csv  # For reading the CSV file
import smtplib  # For sending emails
from email.mime.text import MIMEText  # For email formatting
from email.mime.multipart import MIMEMultipart  # For handling multipart emails

The script uses the following configurations:

port = 1025  # SMTP server port
SMTP_server = "localhost"  # SMTP server address
sender_email = "sender@example.com"  # Sender's email
receiver_email = "receiver@example.com"  # Default receiver (not used in bulk emails)

• The script reads recipient details from a CSV file (personal_data.csv).
• Expected CSV format:

  name,email,grade
  John Doe,johndoe@example.com,A
  Jane Smith,janesmith@example.com,B
  

1. Reading Data from CSV

   with open("personal_data.csv") as file:
       reader = csv.reader(file)
       next(reader)  # Skip the header row

   • Opens and reads personal_data.csv.
   • Skips the header row to process only recipient data.

2. Sending Emails

   for name, email, grade in reader:
       with smtplib.SMTP(SMTP_server, port) as server:
           server.sendmail(sender_email, email, message.format(name=name, grade=grade))
       print(f"Sending email to {name}")

   • Iterates over each recipient.
   • Sends a personalized email using smtplib.SMTP.sendmail().
   • Prints a confirmation message.

3. Email Message Format

   message = """
   subject: Your Grade
   
   Dear {name},
   Your grade is {grade}.
   """

   • Uses a simple text format.
   • Dynamically inserts recipient’s name and grade.

The script sends personalized emails to all recipients listed in the CSV file.

Correct Answer: A. The code sends personalized emails to the recipients in the CSV file.

1. SMTP Server Requirement: Ensure a local or external SMTP server is running on port 1025.
2. Email Formatting: Consider using MIMEText for better email structuring.
3. Security: Avoid hardcoding sender credentials. Use environment variables instead.
4. Error Handling: Implement exception handling to manage connection failures or invalid email addresses.

1. Prepare the CSV File with recipient names, emails, and grades.
2. Run the Script:

   python bulk_email_sender.py

3. Monitor the Output for confirmation messages.

This script provides an efficient way to send bulk personalized emails, ideal for notifications, grading reports, or announcements. 🚀
