if you don't want to lose state upon a page refresh you can use local storage:

handleSubmit() {
  localStorage.setItem('email',
  JSON.stringify(this.state.email));
               }

and then retrieve from local storage on any other page, perhaps in componentWillMount:

componentWillMount(){
  let email = '';
  if (localStorage && localStorage.getItem('email')) {
     email = JSON.parse(localStorage.getItem('email'));
    }
   this.setState({email: email})
}
