+  Important notes:
+    1. Replace "[email protected]", "[email protected]", and "your_email_password" with actual values.
+    2. If you're using Gmail, you might need to use an "App Password" instead of your regular password. You can set this up in your Google Account settings.
+    3. The SMTP server (smtp.gmail.com) is set for Gmail. If you're using a different email provider, you'll need to change this to your provider's SMTP server.
+    4. Make sure to handle the email credentials securely. Avoid hardcoding them in the script. Consider using environment variables or a secure key management system.
