+1. THIS WILL NOT WORK WHEN SENDING MAIL FROM GMAIL BECAUSE OF NEW GOOGLE SECURITY POLICIES.
+2. BUT YOU CAN SEND MAIL FROM OUTLOOK OR ANY OTHER MAIL SERVICES WITHOUT ANY PROBLEM.
+3. ONLY UPDATE 'from_email', 'from_email_password' & 'to_email'.
+4. IF USING ANY OTHER MAIL SERVICE THEN CHANGE THE SERVER AND PORT TOO IN LINE 19 & 20.
