Send Email in Python

In this python project, you will see how we can create a python project that will send bulk emails to a list of emails.

Python code for sending Email

Please check the Instruction before running this code in your Ide. This python code will send emails to a list of email addresses.

import csv
from email.message import EmailMessage
import smtplib

def get_credentials(filepath):
    with open("credentials.txt", "r") as f:
        email_address = f.readline()
        email_pass = f.readline()
    return (email_address, email_pass)

def login(email_address, email_pass, s):
    # start TLS for security
    # Authentication
    s.login(email_address, email_pass)

def send_mail():
    s = smtplib.SMTP("", 587)
    email_address, email_pass = get_credentials("./credentials.txt")
    login(email_address, email_pass, s)

    # message to be sent
    subject = "Welcome to Python"
    body = """Python is an interpreted, high-level,
    general-purpose programming language.\n
    Created by Guido van Rossum and first released in 1991,
    Python's design philosophy emphasizes code readability\n
    with its notable use of significant whitespace"""

    message = EmailMessage()
    message['Subject'] = subject

    with open("emails.csv", newline="") as csvfile:
        spamreader = csv.reader(csvfile, delimiter=" ", quotechar="|")
        for email in spamreader:
            s.send_message(email_address, email[0], message)
            print("Send To " + email[0])

    # terminating the session

if __name__ == "__main__":
