[plt-scheme] What causes error: compile: bad syntax; function application is not allowed, because no #%appsyntax transformer is bound in: (#%top-interaction . list-of-email)

Probably your program did not compile and hence did not even start running 
and hence nothing was bound in the interaction environment.
Use check-syntax to see whether or not your program even compiles.
