a typed list

hi i am new here , hope you are all making a few dollars , i have a typed list of about 2000 email addresses of people who have used the 14 day free trial offered in my previous web site, i wish to send these same people details of my new web site , this one with a 12 day free trial offered, how do i get say 500 of these addresses into my google or yahoo contacts list without typing each one seperately. o know i can only send 500 out using google etc

i can save them to my desktop or scan them wherever , i do not want to type each one, thanks donar:D
