As far as the writer (worked for JS for 18 years till 05/09) is aware there is not a generic email address for Sainsbury's HO. The reliable access method is to phone London (020) 7695 6000 where the well experienced switchboard team if explained a problem will quickly find an extension to connect with. Once contact is made with an individual manager/department, they can issue direct email points as necessary.
