Yes, you do need to commit, which you can execute on the Engine or create a Transaction explicitely. Also the modifiers are specified in the values(...) method, and not execute:

>>> conn.execute(users.update().
...              where(table.c.user=="test").
...              values(email="foo")
...              ) 
>>> my_engine.commit()
