She gave me her email address today but I'm not sure it means anything?

in class today we had this group exercise where we had to ask 10 people in the class for there name and email , but most of the people I asked just gave there student email but 2 of the girls I find attractive in the glass gave me there real emails one was her gmail address and the other her hotmail . but I don't know if it means anything or what . I'm really not that sure if they expect me to contact them at some point or what as they don't really talk to me much and each sit beside guy friends that they talk to a lot but aren't actually dating when in class with me
