Bug fixes for PHP based Mailer application running on Windows

I have a PHP with MySQL ( MariaDB) backend mailer that runs on my Windows system as a local web server. The mailer works fine but needs some bug fixes as follows: 1. Some minor UI fixes such buttons not appearing properly and uploaded emails counter not showing properly on the UI. 2. Mailing process stopping for emails having invalid syntax or when the configured SMTP server times out or not temporary reachable 3. The automated inserted unsubscribe link do not have the correct URL format. But when run on a linux web server, the unsubscribe link is in correct format. Note: Please only bid when you have strong PHP and MYSQL /MariaDB experience and do have a Windows system. The PHP mailer has been bundled into a Windows installer so its important you have a Windows computer. More details will be explained over chat.
