Hi, there, your method is mostly okay, except in the last line. self.assertIn takes 2 arguments, you only pass in one. From the code challenge description.

make sure the email attribute is in the output of the mailto() method

Therefore, you need to add the missing argument to the last line so that self.assertIn knows against what value to test truthiness.

self.assertIn(writer.email, writer.mailto())

And problem solved.
