email track for mailing lists

Hi, I'm using your tool to track who read my messages and the sent urls in it or not. This works really good, when I add people nominally to the email. My problem is that we use mailing lists in the company, e.g. the common all@ lists and so on because it makes easier to communicate.  

Based on my experiences the tool cannot handle these Google groups lists. Are you thinking of extending your solution for that, it would be really helpful,

Thanks,

Bernadett
