Try this:

function Buy() {
  const ss = SpreadsheetApp.getActive();
  const bsh = ss.getSheetByName("Sheet0");
  const esh = ss.getSheetByName("Sheet1");
  const values = bsh.getRange("A2:B7").getValues();
  const email = esh.getRange("E2").getValue();
  values.forEach((v, i) => {
    if (v[0] <= -5) {
      var message = 'Buy Goods ' + v[1]; // Second column
      var subject = 'Buys';
      MailApp.sendEmail(emailAddress, subject, message);
    }
  })
}
