           'schmoe' AS lname, 
           'bogus@bogus.com' AS email_addr
    FROM dual
  UNION ALL                               -- for every row to be inserted
    SELECT 'mary', 'lamb', 'hoe@me.com'
    FROM dual 
                                          -- add another UNION ALL .. FROM dual
  ) AS ins
WHERE NOT EXISTS
      ( SELECT 1 
        FROM email_addr AS e 
        WHERE e.email_addr = ins.email_addr
      )
  AND NOT EXISTS
      ( SELECT 1 
        FROM list_no_email AS ne 
        WHERE ne.email_addr = ins.email_addr
      ) ;
