想让脚本仅将 email 发送到 Google 电子表格中最后添加的一个

Question

This is a script to send emails to the contacts I saved in googlespreadsheets. However, I want it only to send it to the last added email (not all the list). It keeps sending it to everyone included in the list and I want only to send to the last added email in row[2] where are the emails registered.

Thanks.

 function sendEmail(e) {
      var ws = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Form Responses 1");
      var data = ws.getRange("A2:D" +ws.getLastRow()).getValues();
      data.forEach(function(row) {
      var html = HtmlService.createTemplateFromFile("htmlemail.html")
      var htmlText = html.evaluate().getContent();
      var subject = "Thanks for participation";
      var textBody = "This email requires HTML support. Please make sure you open with a client that supports it.";
      var options = { htmlBody : htmlText };
      GmailApp.sendEmail(row[2], subject, textBody, options);
      });
    }

This will only email the last row every time.

function sendEmail(e) {
  var ws = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Form Responses 1");
  var data = ws.getRange(2,1,ws.getLastRow()-1,4).getValues();
  var html = HtmlService.createTemplateFromFile("htmlemail.html")
  var htmlText = html.evaluate().getContent();
  var subject = "Thanks for participation";
  var textBody = "This email requires HTML support. Please make sure you open with a client that supports it.";
  var options = { htmlBody : htmlText };
  GmailApp.sendEmail(data[data.length-1][2], subject, textBody, options);
}

if you do it this way then it will only use that line once unless you edit it with additional emails.

function sendEmail(e) {
  var ws = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Form Responses 1");
  var data = ws.getRange(2,1,ws.getLastRow()-1,4).getValues();
  var html = HtmlService.createTemplateFromFile("htmlemail.html")
  var htmlText = html.evaluate().getContent();
  var subject = "Thanks for participation";
  var textBody = "This email requires HTML support. Please make sure you open with a client that supports it.";
  var options = { htmlBody : htmlText };
  if(data[data.length-1][2]) {
    GmailApp.sendEmail(data[data.length-1][2], subject, textBody, options);
    ws.getRange(data.length-1+2,3).setValue('');
  }
}
