function sendEmails2() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var startRow = 2; // First row of data to process
  // Fetch the range of cells A2:B3
  var dataRange = sheet.getRange(startRow, 1, sheet.getLastRow() - startRow + 1, 4);
  // Fetch values for each row in the Range.
  var data = dataRange.getValues();
  for (var i = 0; i < data.length; ++i) {
    var row = data[i];
    var emailAddress = row[0]; // First column
