is there any way in Mailchimp/mandrill transactional API php to track not opened emails since specifc time

Question

I am using Mailchimp transaction PHP API - Mandrill for sending emails to users. I want to know the status of the outgoing emails and whether the user has opened the email in the past 1 month, 3 months etc, I tried to find any way in the API documentation, checked webhooks etc but didn't find any way/method in Mailchimp transactional PHP API to achieve this. I want to remove those users in our system who are not active and have not opened the email.

Thanks for your help.
