i really want to locate my real mom. i was adopted and i have this huge hole in my heart because i can’t find a free email address finder! i really need to get details from her and not my adopted mother susan. thank you for all your help!!

What internet site can I use to find an email address? Looking for an old friend, and every site I try tells me to sign up for this or that and pay .99 or costs just to get a flippin email address. Is there any truly free email address finder?

I need to send email to my friend but I don’t really remember the exact address he gave. I tried to send to the following address : gotardi_luca@hotmail.com I’m not sure if the address correct or not I try to send many many times but always failed. Is there any free email address finder I can use?
or can anybody help me what to do? thank you!
