Email Automation Script Project (code) in Python

Email Automation Script in Python.

About the project: This is a project for an Email Automation Script in Python. This will be a self-contained script that can send an email automatically from your Gmail account.

Before You Run the Code

This script uses the smtplib and email modules, which are part of Python's standard library, so no installation is required. However, you'll need to configure your Gmail account to allow access for this script to work.

Enable Two-Factor Authentication (2FA): Ensure that Two-Factor Authentication is enabled for your Google account.

Generate an App Password: Go to your Google Account settings, navigate to the "Security" section, and find the "App passwords" option under "2-step Verification." Create a new app password for a custom app (e.g., "Python Email Script"). This will generate a unique 16-character password. You must use this app password in the script, not your regular Gmail password.

This script will prompt you for the sender's email address and the recipient's email address and then send a pre-defined email message.

This project provides a basic but functional email automation script. You can run it directly from your terminal after setting up the App Password for your Google account.
