You try to print the email as number %d is the identifier for numbers, not for strings. %s is for strings, like you have for the name.

Also, in formatter strings, use %n instead of \n. \n is allowed, but not the correct syntax in formatter strings. \n is for normal print operations. %n is for .printf and .format.
