if the form is invalid send the form back with the data in your request. For example in your form validation else statement should be something like this:

return render(request, 'account/my login/register.html',{'form':form})

If you want to send only the email field back then clean the other fields in the form except for the email and send only the email data back.

        if form.is_valid():
                # form validation logic here
        else:
            return render(request, 'account/my login/register.html',{'form':form})
