AND binds more tightly than OR.  I think you meant

where p.email is not null and
(industry = 'Chemicals' or
industry = 'Energy' or
industry = 'Food processor' or
industry = 'Manufacturing' or
industry = 'Maritime' or
industry = 'Transportation' or
industry = 'Wood products')

BTW, using IN might make this more compact.
