In Givebacks, like most other online apps, an email address can only be associated with one person/profile because it is the unique identifier for that person.
Students are not required to have an email address.
If you need to enter non-student members and do not have a second email address, one member can be entered using just a phone number; however, please note that this will mean that this person will not have the ability to log in to Givebacks under their own profile.
If you do not have a phone number for the second person, you can enter it using a made-up number or "dummy" information.
