Project description:

I made a friend online about 4 years ago. At some point, she no longer wanted to talk to me and stopped responding. We had contact through email, but I’m pretty sure the email address she used was not her main email address. 

I think her main email address will be the email address that she has used as a recovery email address for the email address that she used to contact me. I was wondering if it is possible to hack her email account so I can find out what her other email address is so I can message her. 

I am also wondering if it is possible to trace her at all through just her email address? And if so, what is it that can be traced? I would really like to get back in contact with this person.
