My idea was the same as yours i had trouble with the implementation. Your solution cleared it up and was really simple. Thanks man.

quick question if u may, why does it work when lookup is a set and doesnt work when it's a list? What's the difference and why did u choose to use sets not lists or tuples?

We have to make sure the emails are unique, hashset is the easiest way to do that
