Import All Required Libraries

Before you start sending emails with Python, you need to import the necessary modules that handle sending, formatting, and securing your messages.

Start with this code:

import os
import smtplib
import ssl
from email.message import EmailMessage

What Each Library Does:

• os

  • Used to read environment variables (like email username and password) securely.

  • 🔐 Helps keep credentials hidden and not hard-coded in your script.

• smtplib

  • Handles the SMTP protocol, which is used to send emails.

  • It connects your Python script to the mail server (like Gmail).

• ssl

  • Establishes a secure, encrypted connection with the mail server.

  •  Important when sending sensitive information.

• EmailMessage (from email.message)

  • Helps you create a properly structured email with subject, body, sender, and receiver.

  • Makes your code cleaner and easier to manage when formatting email content.
