Need Email Sending Site Fixed

I was having trouble with my website [login to view URL] and wanted to know if you can help fix. Here are the edits: 1. The site is a emailing software (similar to MailChimp alternative - uses AcelleMail), and it uses a ElasticEmail API to send email. A problem we have is that it doesn’t track opens/clicks correctly. It tracks them correctly on ElasticEmail but it doesn't list them on the site. I want to have this fixed so that it works properly. Picture attached. 2. When sending emails, the unsubscribe button sometimes doesn't work when sending emails through the software. The Update preferences button work but the unsubscribe leads the user to a broken Apache page. Budget is $25. These two things are all this project is. Thank you.
